INDUSTRY CANADA REQUIREMENTS Load Number: 5 CP-01, Part 1 Section 10.1 “NOTICE: The Canadian Department of Communications label identifies certified equipment. This certification means that the equipment meets certain telecommunications network protective, operational and safety requirements. The Department does not guarantee the equipment will operate to the user’s satisfaction. Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. In some cases, the company’s inside wiring associated with a single line individual service may be extended by means of a certified connector assembly (telephone extension cord). The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations. Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment. Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas. CAUTION: Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate.” CP - 01, Part I Section 10.2 “NOTICE: The Load Number (LN) assigned to each terminal device denotes the percentage of the total load to be connected to a telephone loop which is used by the device, to prevent overloading.

summaries of its: • Physical Characteristics • Features, Functions, and Optional Enhancements • Digital and Analog Interfaces and Connectors • Local and Remote Network Management 1.2 General System Overview The Access Bank II SNMP is an intelligent dual-port T1 voice and data multiplexer equipped with integrated pairs of Channel Service Units (CSUs) and Data Service Units (DSUs). It supplies up to 9/24/01 1-1 3.072 Mbps of synchronous bandwidth capacity for connecting customer premises telecommunications equipment to public and private network DS1 services. An Internet or router V.35 port may be configured for up to 1.5 Mbps on one T1, while all 24 voice channels are terminated on a second T1. 1.3 Features, Functions, and Options The Access Bank II SNMP combines the functions of an intelligent CSU/DSU, digital access & cross-connect switch (DACS), and channel bank in a single product that includes the following standard features, functions, and options. 1.3.1 Standard Features • Dual T1 ports with integrated diagnostic ESF CSUs • 3.08Mbps total available bandwidth • V.35 DCE data port (to 1.536Mbps) • Drop and Insert (D&I) • DS0 Digital Cross-Connect System (DCS) • Command line interface (CLI) for local or remote mangement. • RS-232 Command Line Interface and optional Remote Monitor program. • Embedded SNMP agent supporting MIB-II and standard MIBS for T1 and V.35 via a TCP/IP and 10base-T Ethernet connection • 115 Vac to -48 Vdc Power Converter Cube • Standard 25-pair female telephone cable connector 1.3.2 Software Programmable Functions • Drop & Insert (D&I): 1 T1/CSU with 1 T1/CSU D&I port • 2 T1/CSU DSO Digital Cross-Connect (DCS) with three frames maximum (0.375ms) T1-toT1 delay • Bandwidth allocations of voice and data • ESF to D4 (SF) and D4 to ESF conversions for PBXs with T1 interfaces • Time of day DS-0 mapping to optimize voice and data utilization 1.4 Dual T1/CSU Network Interfaces Because the dual T1 network interfaces supply over 3 Mbps of useable bandwidth, the Access Bank II SNMP is able to demultiplex the primary incoming T1 signal into 12 or 24 analog telephone circuits for connection to voice, facsimile, and high-speed V.34 modems, leaving the secondary T1 port 1-2 9/24/01 Digital Data Ports available for Internet connection, or for alternate routes or carriers. Doubling the bandwidth capacity of a conventional digital channel bank allows the Access Bank II SNMP to dedicate the built-in V.35 DCE data port to Internet, video, or Wide-Area Network (WAN) applications, while also performing such advanced networking tasks as Drop and Insert (D&I), and DS-0 Digital Access & Cross-connect Switching (DACS). Both diagnostic CSUs are fully integrated, respond to all standard inband and out-of-band network loop codes, and can be polled for ANSI T1.403 one-second Performance Report Messages (PRMs) or AT&T 54016 Maintenance Messages over the 4 Kbps ESF Facility Data Link (FDL). 1.5 Digital Data Ports 1.5.1 V.35 DCE Port To fully utilize the extra bandwidth supplied by the dual T1 interfaces, the Access Bank II SNMP has a built-in V.35 DCE data port for connection to Wide Area Network (WAN) devices such as Internet routers and Frame Relay Access Devices (FRADs). This high-speed serial interface supports synchronous data connections from 56 Kbps to 1.536 Mbps, all rates. When used in conjunction with the internal BER tester, the V.35 interface is also capable of generating V.54 loop codes for activating and deactivating remote loopbacks in DCE devices at the far-end. The intervening transmission link then can be stress tested using a selectable range of industry standard QRSS patterns (QRSS, All Zeros, All Ones, 511, 2047, 215-1, 220-1, 2023-1, etc.). Use of the V.35 DCE port requires an optional V.35 data cable. 1.5.2 RS-232 Data Port The Control Panel of the Access Bank II SNMP also contains an RS-232 secondary data port that can be configured to provide a 56/64 Kbps synchronous data channel for connection to SNA cluster controllers, data multiplexers, routers, or SCADA (Supervisory Control and Data Acquisition) links. When configured for asynchronous operation, this same RS-232 data port can also be used, alternately, to implement a point-to-point dedicated communications channel between two Acess Bank II units at 1.2, 2.4, 4.8, 9.6, 14.4, 19.2, 28.8, 38.4, or 57.6 Kbps rates. Use of the RS-232 data port requires an optional dual purpose RS-232 user data and management cable. 1.6 Analog Line Interfaces: FXS, & FXO, and 4-Wire E&M To meet individual site-specific communications requirements, the Access Bank II SNMP can be equipped with a full range of “hot-swappable” slide-insert analog line interface cards. Please contact CAC for details and availability of these and other card options: • The Foreign Exchange Station (FXS) 12-channel voice card delivers high quality loopstart or ground-start dial tone telephone line connections to key systems, Off Premise Extensions (OPXs), facsimile machines, modems, PBXs and other conventional analog telephone devices. • The Foreign Exchange Office and Dial Pulse Termination (FXO/DPT) voice card compliments the FXS by supplying 12 standard loop-start or ground-start telephone line con- 9/24/01 1-3 nections on a per channel basis from PBX office-end telephone systems to public network T1 (DS1) services using FXO terminations. The DPT feature of this card is especially useful in remote office or campus T1 environments where it can be used to support one-way Direct Inward Dialing (DID) service for voice mail and call center applications. • A Battery Reversal FXS/Dial Pulse Origination (BRFXS/DPO) voice card is also available that provides twelve 2-wire Loop Start connections with Tip/Ring battery reversal to the digital T1 (DS1 line). The second function of this card is Dial Pulse Origination (DPO), which is the functional complement to Dial Pulse Termination (DPT) provided by the FXO/DPT voice card. • The 4-wire E&M/Transmission Only (E&M/TO) voice card supplies 12 channels for connecting to private line circuits, such as PBX tie lines and 4-wire modems often found in utility, cellular, and metropolitan area networks (MANs). Each of the twelve E&M channels can be individually programmed to support Signaling Types I, II, IV or V. This card can also be configured to function as Channel Equipment (normal multiplexer mode) or as Switching Equipment for back-to-back Tandem operation sometimes referred to as “Reverse E&M” or “Pulse Link Repeater.” The Transmission Only (TO) operating mode provides dedicated transmit and receive paths to radio and modem equipment uncorrupted by the insertion of A/B robbed bit signaling. All analog line interface cards greatly exceed the required analog loop range and are proven V.34 modem compatible. Using a special patent-pending feature developed by Carrier Access Corporation, they also perform automatic impedance matching to adapt to various analog modem types and line lengths. Over-voltage and over-current protection are individually handled on the analog interface channel cards, as well as on the Controller. This distributes the power redundantly so that a line fault or over-voltage on one analog channel card does not affect the operation of another. 1.7 Local and Remote Network Management The Access Bank II SNMP has three network management options. SNMP and CLI management are described in detail in Chapter 14, SNMP Management and Command Line Interface, while GUI management software is provided in the Access Bank II SNMP User Manual. • Simple Network Management Protocol (SNMP) for basic network control by a Network Management Station via the Ethernet 10Base-T management port. • Command Line Interface (CLI) for complete control by a VT-100 terminal via the RS232 port, or by a Telnet terminal via the Ethernet 10Base-T port. • Windows®-based GUI software with graphical user interface (GUI) for user-friendly control by a PC or laptop computer via the RS-232 port. 1.7.1 Local/Remote Mode Selection The Access Bank II SNMP comes equipped with two sets of external DIP switches for selecting local or remote management control. In the local hardware control mode, you can use these DIP switches to perform self-tests for channel alignment, to select basic T1 hardware configuration parameters 1-4 9/24/01 Local and Remote Network Management (AMI/B8ZS, D4/ESF), and to enable detection of standard D4/ESF inband loop codes by the integral CSUs. In the remote software control mode, you can use SNMP, CLI, or GUI management terminals. 1.7.2 SNMP Management The Access Bank II SNMP: • Supports Simple Network Management Protocol version 2 (SNMPv2) through its Ethernet 10Base-T port. • Complies with RFC standards for for SNMPv2, Ethernet, Internet, TCP/IP, and MIB-II network management, and T1 and RS-232 interfaces. • Has built-in SNMPv2 Agent software providing network statistics, information retrieval and update, trap thresholds, and automatic transmission of trap data to Network Management Stations. 1.7.2.1 Local and Remote SNMP Management The Access Bank II SNMP provides SNMP management through its Ethernet 10Base-T port. Remote SNMP management is possible over either of the T1 lines within a V.35 user data segment, as shown in Figure 1-1. Remote Control SNMP in data stream V.35 Frame or IP Network T1 Access Bank II SNMP SNMP Manager Router Ethernet 10Base-T LAN Local Control SNMP Manager Figure 1-1: Local and Remote SNMP Management 1.7.2.2 SNMP Overview SNMP is a complete, but simple, mechanism for network management. It works by exchanging information between a Manager and an Agent. In this case, the Agent is inside the Access Bank II/SNMP. The Manager is a Network Management Station (NMS), which is a computer with SNMP management software such as HP OpenView® or Sun NetManager®. The Agent stores the information in a Management Information Base (MIB), which contains items such as the current status of the network interface, performance statistics, and alarms. In general, SNMP is not concerned with controlling every feature of the many different network objects. However, SNMP is flexible enough that it can support a wide variety of private enterprise objects with predefined MIB data structures. The Access Bank II/SNMP uses the Bellcore® standard MIB for T1 interfaces. Manager operations include simple “get” and “set” commands to retrieve and update MIB data in the 9/24/01 1-5 Agent. Normally, the Manager polls the Agent periodically to check traffic statistics. However, the Manager can also set thresholds for traps. Traps specify network events and conditions for which the Agent automatically sends a Telnet alarm message with trap data back to the Manager. 1.7.3 Command Line Interface The Access Bank II SNMP comes with a built-in Command Line Interface. CLI provides complete management of all Access Bank features through any VT-100 terminal or PC connected to the RS232 port, or through any Telnet terminal connected to the Ethernet 10Base-T port. CLI works with a communications terminal, in which you type in text and press the carriage return key to send the message to the host. The host then responds with a log-on message, and the CLI is ready to use. CLI is easy to use because the Access Bank II SNMP provides a list of menu options to choose from. Furthermore, context sensitive help is available to guide you through the setup process. At any time, you can type in a question mark (?) to obtain information about what to type next or what commands are available. You can also type “help” after any command to get specific help with that command. 1.7.3.1 Local and Remote CLI Management The Access Bank II SNMP provides CLI management through its RS-232 and Ethernet 10Base-T ports, as shown in Figure 1-2 and Figure 1-3. For RS-232 CLI control, just connect a PC or laptop computer to the RS-232 management port on the Access Bank II/SNMP. Then use a VT-100 terminal emulation program such as Microsoft Hyper Terminal®. (The default communications port settings are 9600, 8, 1, N.) Press the Escape key to initiate the link. The Access Bank will return a log-on message. If a password is required, the Access Bank will request that you enter a password. (Units shipped from the factory do not have a password defined, but the user is encouraged to use passwords to prevent unauthorized use.) CLI can be used from a remote site by connecting the RS-232 port to a modem and telephone line. .

Remote Telnet CLI operation is available using Telnet over Ethernet or using inband T1 via the V.35 data port. 1.7.4 Windows-Based GUI Management Software The Windows®-based GUI Management software (Figure 1-4) provides a graphical user interface (GUI) that makes management as easy as clicking a mouse button. Pull-down menus and Index Tabs make it easy to find just the function you’re looking for. CAC’s GUI Management software provides convenient access to most features of the Access Bank II SNMP. For detailed software description, see Access Bank II SNMP User Manual. . Figure 1-4: Carrier Access Corporation’s GUI Management Software The GUI software follows a top-down hierarchy that organizes Access Bank management functions into six basic groups. Index tabs at the top of the screen give quick access to: 9/24/01 1-7 • PC Setup • Configuration • Connections • Hardware Setup • Performance Statistics • Maintenance 1.7.5 Local and Remote GUI Management For configuration, monitoring, and testing purposes, each Access Bank II SNMP is shipped with CAC’s Windows®-based GUI management software, backed by a full-featured system of contextsensitive online help. Installed on a local 486 (or higher) IBM-compatible PC equipped with at least 16 MB RAM, Windows 95®, a keyboard and a mouse, this software program provides a convenient user-friendly interface for configuring and monitoring the performance of the Access Bank II SNMP via the RS-232 management port (Figure 1-5). . Remote Control FXS Modem Telephone Network T1 Access Bank II SNMP Modem Local Control RS-232 Windows Computer Windows Computer Figure 1-5: Local and Remote GUI Management The GUI management software can also be installed on a remote Windows® PC for management over a separate PSTN (Public Switched Telephone Network) analog line. In this application, the GUI management software can also be used to poll the Access Bank II SNMP for remote alarms via an external Hayes®-compatible modem attached to the RS-232 management port. 1.8 Design Philosophy The Access Bank II SNMP is manufactured by CAC according to a design philosophy based on solid-state overvoltage and overcurrent protection without the use of low-current fuses (<1 A) or very high-wattage resistors. Thanks to this advanced new technology, the Access Bank II SNMP complies fully with National Electrical Code and UL 1459 requirements for the safety of equipment attached to telephone wiring without using any fuses, which dramatically improves its long-term reliability, while greatly reducing equipment down time. As an added benefit, all items of equipment connected to the Access Bank II SNMP are protected from transient network voltage or current surges. 1-8 9/24/01 About This Chapter Chapter 2 Product Description Contents of This Chapter: About This Chapter .................................... 1 Physical Characteristics ............................. 1 Control Panel Interface Connectors ........... 2 Control Panel DIP Switches ....................... 3 LED Test and Status Indicators ................. 3 2.1 About This Chapter This chapter describes the general physical characteristics and layout of the Access Bank II - SNMP, including its: • Dual RJ-48C Jacks for T1 Span 1 and Span 2 • V.35 and RS-232 Digital Interface Ports • Power Source Connector • Standard 25-pair RJ-21X Tip & Ring Telephony Connector • T1 Span and System Setup DIP switches • LED Test and Status Indicators 2.2 Physical Characteristics The Access Bank II - SNMP consists of a painted sheet steel chassis housing, nickel-plated chassis tray and removable back plate that accepts one (or two) 7.8 inch by 13.16 inch analog line interface daughter card(s).

Prior to mounting the Access Bank II - SNMP chassis, ensure that the installation site meets the following criteria: • Adequate clearance for access to control panel DIP switches, cable routing, and ventilation. Leave at least 18 inches behind the back plate for maintenance and accessing the slide-in voice cards. • Because the cables on the power conversion cube total 13 feet in length, there should be a properly grounded, 110 VAC power outlet within 10 feet of the Access Bank II - SNMP Control Panel. • A stable environment, clean and free from extremes of temperature, shock, vibration and EMI, with a relative humidity between 0 and 95%. • An ambient temperature that stays below 40 º C (104 º F). 9/24/01 4-3 ! Caution: If the operating temperature rises above the 40 º C limit an internal thermal protection device will shut off the Access Bank II - SNMP. When the temperature is reduced below this threshold, the Access Bank II - SNMP restarts. • An installation site below 10,000 feet (3,048 m). • For operation outside these ranges, the Access Bank II - SNMP must be placed in an environmentally controlled enclosure. ! Caution: When you mount the chassis, do not allow the Access Bank II SNMP to remain in direct contact with any combustible surface. 4.4 Wall Mounting The adapter brackets attached to the Access Bank II - SNMP are positioned at shipment for wallmounting. To wall-mount the unit: 1. Select a location that meets the criteria specified above. Leave at least 1/2 inch clearance below the chassis for ventilation. Leave at least 6 inches in front of the Access Bank II SNMP Control Panel for access to its switches and LEDs and at least 18 inches behind the back plate for maintenance. 2. To create a 3/4 inch offset between the Access Bank II - SNMP chassis and the wall surface for better ventilation, mount a 3/4 inch thick piece of plywood (at least 20 inches vertically by 14 inches horizontally) on the wall using fasteners appropriate for mounting a heavy object (see Figure 4-1). 3. Mount the Access Bank II - SNMP chassis to the plywood with eight #8 x 3/4” pan-head (or larger) wood screws (Figure 4-1). 4.5 Rack Mounting The Access Bank II - SNMP can be rack-mounted using several different methods. The small adapter brackets shipped with the unit can be used to mount the unit in a standard 19” rack with a typical fiveinch offset. Using the recommended heavy-duty brackets, you can mount the Access Bank II - SNMP in either a 19” or 23” rack with a custom offset. 4-4 9/24/01 Surface Mounting 4.5.1 Rack Mounting with Brackets Shipped with Unit To mount the Access Bank II - SNMP in a standard EIA 19-inch Telco equipment rack using the included adapter brackets: 1. Remove the two front adapter brackets, rotate them 90 degrees and re-attach the brackets so they face toward the unit back plate (Figure 4-2). This creates a standard five-inch offset mounting typical of telecommunications equipment. 2. Select an appropriate location in the rack with at least 1 3/4 inches of clearance above and below the chassis for ventilation. Also ensure that there is at least 6 inches in front of the Control Panel for access to its controls and DIP switches, and at least 18 inches behind the back plate for maintenance. 3. Mount the chassis using 10-32 x 3/4” machine screws appropriate for a Telco rack (Figure 43). Note: The optional heavy-duty rack mounting brackets (see Figure 4-4) can significantly increase static strength and provide a custom front-to-back offset when mounting the units on either 19” or 23” racks (see Figure 4-3). 4.5.2 Mounting with Heavy-Duty Brackets 1. Remove the four small front adapter brackets from the Access Bank II - SNMP. 2. Attach the heavy-duty brackets to the Access Bank II - SNMP using the screws included in the heavy-duty bracket kit (see Figure 4-3). 3. Select an appropriate location in the rack with at least 1 3/4 inches of clearance above and below the chassis for ventilation. Also ensure that there is at least 6 inches in front of the Control Panel for access to its controls and DIP switches, and at least 18 inches behind the back plate for maintenance. 4. Mount the chassis on the rack using 10-32 x 3/4” machine screws appropriate for a Telco rack (Figure 4-3). 4.6 Surface Mounting To surface-mount the Access Bank II - SNMP as a desktop stand-alone, simply place it on a flat, stable, non-combustible surface with at least 1/2 inch ventilation clearance below the unit. Leave at least 6 inches in front, and 18 inches in back of the chassis for ventilation and access to its controls. Leave at least 3/4” above the chassis for required ventilation. 9/24/01 4-5 4.7 Mounting the Power Converter The Access Bank II - SNMP is normally shipped for US operation with a 115 Vac to -48 Vdc power conversion cube. This cube includes both a 5-foot grounded AC power cord and a 8-foot three-position DC power cable. The Power Converter Cube has four mounting holes for attaching the unit to a wall or other flat surface. To mount the Power Converter Cube on a nearby wall, locate the converter within 7 feet of the Access Bank II - SNMP front Control Panel and use screws or anchors appropriate to the mounting surface. If you are wall mounting the power conversion cube on the same ¾” thick plywood sheet as the Access Bank II - SNMP, the dimensions of the board will have to be at least 25” by 14”. Wire tie-downs can be used to keep stray wires to a minimum, but be careful not to damage the wiring in any way.

These cables eliminate the use of the front panel RJ-21X Tip & Ring telephone connector. 5.4 Connecting the Voice Circuits Voice circuit connections are made at the 50-pin Amphenol jack labeled Tip & Ring on the Access Bank II SNMP Control Panel (see Figure 5-1). You will need a standard 25-pair telephone cable with RJ-21X wiring and a D-type mating connector at the Access Bank II SNMP end. The other end connects to either a punch down block or an RJ-11 “Harmonica” for interfacing to analog telephony equipment. To connect the voice circuits: 1. Connect the telephone cable to the punch-down block or RJ-11 “Harmonica.” 2. Route the cable to the Access Bank II SNMP Control Panel. 3. Remove any screws in the D-type connector that may prevent a flush connection with the Tip & Ring jack. 4. Connect the D-type mating connector to the Tip & Ring connector on the Control Panel. 5. Cinch down the attached Velcro strap to retain the connectors. 6. Use the cable tie down on the unit and elsewhere to avoid accidental disconnection. Note: If you are connecting an external alarm, note in Table 5-2 that pair 25 of the voice drop cable provides a connection to a set of normally open relay contacts (150 Vrms, 150 mA maximum load) that close when the Access Bank II SNMP enters an alarm state. For more information on external alarm events, see the Remote Monitor section of this manual and the separate Remote Monitor User’s Guide.

Procedures are provided for: • Installing the Remote Monitor software program • Logging into the PC database • Selecting a profile and default configuration • Modifying Selecting Cross-Connect configurations • Configuring the Dual T1 Hardware Interfaces • Configuring the V.35 DCE Data Port • Configuring the RS-232 Management Port • Enabling Alarm Reporting to Pagers and Remote Printers A more detailed explanation of the operation of the Remote Monitor is provided in the Remote Mon- 9/24/01 7-1 itor User’s Guide. 7.2 Remote Monitor Software Program 7.2.1 Overview The Access Bank Remote Monitor software interface is used to configure and manage the Access Bank via the RS-232 Management Port. Installed on a local IBM-compatible PC or laptop connected to the RS-232 Management port, Remote Monitor provides a convenient user-friendly software interface for configuring, monitoring, and testing the performance of the Access Bank. The Remote Monitor software can also be downloaded into a remote computer for dial-in/dial-out management over a separate PSTN (Public Switched Telephone Network) analog line. In this application, Remote Monitor can also be used to poll the Access Bank for remote alarms via a Hayes-compatible modem attached to the secondary connectors of the RS-232 Management port. Figure 7-1 illustrates these two different ways of connecting Remote Monitor to the Access Bank. Windows Based Remote Monitor Modem Modem Windows Based Remote Monitor Access Bank II Access Bank II Figure 7-1: Remote Monitor Connections 7.3 Message Traffic The Remote Monitor software supports three classes of message traffic between the PC and the 7-2 9/24/01 Online Help Access Bank: configuration traffic between the PC and the Access Bank, status traffic from the Access Bank to the PC, and alarm report messages from the Access Bank to the PC. The X-modem protocol is used to send/receive data from the Access Bank. A low-priority process resides in the Access Bank to process the X-modem packets and update the internal data structures accordingly. Statistical data and error handling are processed by internal processes and sent to the remote monitor via X-modem packets. The Remote Monitor software can also be used to perform V.54 loopback testing to sectionalize and stress test the V.35 remote link using a full array of industry standard QRSS test patterns. 7.4 Online Help If you need specific information on performing any Remote Monitor operation, press the F1 key from any screen to access a detailed system of context-sensitive online Help. When you place the cursor over certain control fields, Remote Monitor also responds with handy tips for performing that particular task. For step-by-step instructions on all aspects of installing, configuring and operating the Remote Monitor GUI software interface, refer to the separate Remote Monitor User’s Guide. If you need information on using Microsoft Windows, refer to your Windows documentation. 7.5 Hardware Requirements The PC you use as a Network Management Station (NMS) should meet these minimum requirements: • 486 66 MHz or Greater (Pentium 100 MHz -preferred) CPU • 16 MBytes RAM memory • 10 Mbytes available hard disk space • VGA monitor with 640 x 480 resolution and 8-bit (256 colors) color • Windows 3.1/Windows 95 • Keyboard • Mouse 7.6 Installation The Remote Monitor software is distributed on four 3 ½ “ diskettes and is designed to operate under both Windows 3.1 or Windows 95 environments.

The FXS - ID card supports the Caller ID CLASSÆ feature. The FXS -ID, is a 7.8” by 13.16” daughter card designed to slide into the back of the Access Bank II - SNMP along rails that guide a 64-pin DIN connector to mate with a matched connector on the internal AB2 Controller. The FXS-ID card receives the T1 signaling, tip and ring pairs, control logic and power through this connector. The back 9/24/01 8-1 FXS-ID Configuration plate of the FXS-ID card has 12 channel status LEDs and one 4-position DIP switch for selecting from a number of different signaling types. Furthermore, the back plate also contains 12 test switches that can be used to “busy out” each channel individually. On the FXS-ID card itself, each individual channel has a 6-position DIP switch for setting transmit and receive line attenuation. When equipped with the Foreign Exchange Station - Caller ID (FXS-ID) voice card, the Access Bank II - SNMP can support a number of popular signaling types used by dedicated T1-accessed voice service providers, including: • AT&T Megacom (E&M Wink-Start) • NYNEX Flexpath“ (E&M Wink-Start) • US West DSS“ • Long-distance Automatic Number Identification (ANI) and Dialed Number Identification Service (DNIS) from MCI, Sprint, LDDS, and Wiltel. The FXS circuits automatically perform impedance matching (not to be confused with DS-1 ALBO) to adapt to various PBXs, key systems, telephones and line lengths. 8.3 Signaling Types The FXS-ID voice card can be configured, using DIP switches on the card, to support the following common signaling types: • FXO in the Central Office (CO)-to-AB2 FXS A/B Signaling (regular 3-state FXS signaling) • E&M Immediate Start to Loop-Start/Ground-Start • Wink-Start to Loop-Start/Ground-Start • Wink Delay (ANI/DNIS) for Loop-Start/Ground-Start 8.3.1 FXO Switch to AB2 FXS A/B Signaling Select the default setting to have Access Bank II - SNMP FXS interfaces automatically adapt to loopstart or ground-start signals received from the incoming T1 line on a channel-by-channel basis. This option is used when an FXO voice card is in the Central Office, at the other end of the T1 link opposite the FXS-ID card. It is important to note that in this configuration, the Caller ID CLASS feature can only be supported if the FXD voice card in the CO also supports this feature. 8.3.2 Wink-Start to Loop-Start or Ground-Start Select Wink-Start to Loop-Start or Ground-Start to translate two-state wink-start signaling from the T1 network (AT&T Megacom, Flexpath, etc.) to loop-start or ground-start ringing at the FXS interface. Ringback tone is supplied on the T1 transmit path during the ringing state of the FXS. This configuration options all 12 FXS channels to appear as E&M wink-start channels to the serving carrier switch, while providing the customer with standard dial tone/ringing telephone line connections. 8-2 9/24/01 Setting the FXS Transmit and Receive Levels 8.3.3 Wink Delay Select Wink Delay to translate two-state wink-start signaling toward the T1 network to an FXS ringing with delayed wink for proceed-to-send digit indication. Upon detection of an incoming seizure from the T1 network, the AB2 applies ringing voltage to the FXS channel. When the attached equipment answers by closing the loop, the Access Bank II - SNMP winks the network for “proceed to send,” allowing the attached equipment to receive DTMF digits carrying Automatic Number Identification (ANI) or Directory Number Identification Service (DNIS). This is particularly useful for voice mail, voice response, call distribution, and automatic attendant applications. Standard loop-start PC voice mail and fax cards can be used for ANI and DNIS applications, without the added expense and complexity of installing signaling converters. 8.4 Setting the FXS Transmit and Receive Levels The transmit and receive attenuation levels for each FXS voice frequency channel can be set between 0 and -9 dB using twelve 6-position DIP switches (CH1 - CH12) on top of the circuit board (see Figure 8-1). Each analog channel uses a bank of six DIP switches, with three for transmit and three for receive. Operation of each set of three switches in additive. For example, setting switch 1 (-2 dB) and switch 2 (-3 dB) to OFF for any given channel selects a receive loss of -5 dB. The default setting for the transmit level is -3 dB; for the receive level it is -6 dB. The default settings are appropriate for most applications.

Release the two thumbscrews on the AB2 back plate and remove the plate (see Figure 8-2). 2. To remove the FXS-ID slide-in voice card, pull out the two card ejector latches simultaneously to release the card from the internal connector, then slide the card carefully out from the rear of the AB2 chassis (see Figure 8-2). 3. To set different transmit and/or receive gain or loss levels, refer to Figure 8-1 and Table 8-1. 4. To reinsert the FXS-ID voice card, ensure that the card is positioned correctly in the card rails, then carefully slide the card into the slot until it stops. 5. Press both card ejector latches in towards the FXS-ID card to seat the 64-pin DIN connector in the matching connector on the internal Controller card. 6. After setting the transmit and receive level options, replace the back plate and tighten the thumbscrews.

Please contact Carrier Access Corporation for specific details (Note 4). Note 1: Loop release implemented to prevent follow-up calls until the network A/B clears (no timer). Note 2: Calling party disconnect implemented as a 2-second tip-open state when the network A/B clears. Note 3: Wink-out provided after loop answer instead of after network seizure. This is the key difference between options 1 & 2 and options 5 & 6. Note 4: If you select this DIP switch setting with no custom signaling option installed, the 12 channel LEDs on the FXS back plate turn a steady RED and normal service is interrupted. 8.5 Setting the FXS Signaling Options Each FXS-ID card contains one 4-position DIP switch that can be used to select signaling options for all twelve channels. As shown in Table 8-2, the AB2 back plate provides openings for accessing these DIP switches, one per FXS-ID card. 8.5.1 Option Switches A, B, and C The three switches labeled Option A, Option B, and Option C are used as a group to select signaling conversion options for all 12 channels of each FXS-ID card. When all three switches are set OFF (default), the FXS voice circuits will automatically select ground-start or loop-start signaling on a channel-by-channel basis according to the incoming T1 signal. See Table 8-2 for all switch combinations. TP Idle/Busy Switch The fourth switch on each DIP switch, labeled TP Busy/Idle, selects whether the tip-ground relays are busy (closed) or idle (open) during trunk processing. The default is idle (switch 4 OFF). To change signaling options, refer to Table 8-2 and Figure 8-3. The numbered signaling options listed in Table 8-2 are described in further detail in the next section. 8-6 9/24/01 FXS Signaling Option Descriptions Signaling Options & Busy/Idle Signaling Options & Busy/Idle Figure 8-3: FXS Signaling Options 8.6 FXS Signaling Option Descriptions 8.6.1 Option Switches A, B, and C Signaling options selected by the A, B, and C option switches are discussed below according to the numbered sequence from 0 to 7 in Table 8-2. 8.6.1.1 Option 0. Normal FXS A&B Signaling, Loop-Start or Ground-Start Switch A OFF Switch B OFF Switch C OFF With this selection, the Access Bank II - SNMP FXS interfaces automatically adapt to loop-start or ground-start signaling received from the T1 line on a channel-by-channel basis. When using this option, order FXS loop-start or FXS ground-start signaling from your service provider. 8.6.1.2 Option 1. E&M Wink-Start-to-Loop-Start Conversion with Calling Party Disconnect Switch A ON Switch B OFF Switch C OFF The FXS-ID voice card provides Plain Old Telephone (POTS) loop-start interfaces to a PBX or regular telephones. E&M wink-start signaling and per-channel ringback tones are sent to the T1 line. Calling Party Disconnect Calling Party Disconnect (CDD) is a 2-second, tip-open condition at the FXS-ID when the network releases seizure (the far-end called party hangs up). The battery feed from the FXS-ID returns to idle (tip grounded) after the two-second disconnect. This feature is similar to local telephone service Calling Party Disconnect (CPD), which some Central Office equipment provides for answering machines and PBXs equipped to detect loss of loop current on their line interfaces. This loss of loop current 9/24/01 8-7 FXS-ID Configuration informs the equipment to hang up. 8.6.1.3 Option 2. Wink-Start to Ground-Start Conversion Switch A OFF Switch B ON Switch C OFF POTS Interface This option provides a POTS (Plain Old Telephone Service) ground-start interface between the Access Bank II - SNMP and the PBX or other phone equipment. This avoids both-way call collisions (“glare”) on PBX trunks and gives the PBX a disconnect signal when the far-end party hangs up. E&M wink-start signaling and ringback tones are sent to the T1 line on an individual channel basis. This option is for use with AT&T Megacom, NYNEX Flexpath or equivalent E&M services from other service providers. 8.6.1.4 Option 3. E&M Immediate-Start-to-Loop-Start Conversion Switch A ON Switch B ON Switch C OFF Private Line Automatic Ringdown (D3 PLAR) Known as D3 Private Line Automatic Ringdown (D3 PLAR), this option provides a “hot-line” ring down function from the near-end telephone to the far-end telephone connected over the same channel of the T1 line. The first telephone to go off-hook seizes the channel with a signaling bit sequence of A/B = 11 and hears a cadenced ringback tone (2 seconds on, 4 seconds off) from the far-end channel bank. The far-end disconnects the ringback tone and sends A/B = 11 to the originating end when its telephone goes off-hook. D4 PLAR is not supported. To use this option, order E&M immediate-start service from your service provider. 8.6.1.5 Option 4. E&M Immediate-Start-to-Ground-Start Conversion Switch A OFF Switch B OFF Switch C ON This is the same as the E&M immediate-start-to-ground-start conversion option for services such as AT&T Megacom and NYNEX Flexpath. To use this option, order E&M immediate-start service from your service provider. 8-8 9/24/01 FXS Signaling Option Descriptions 8.6.1.6 Option 5. Wink-Start to Loop-Start Conversion with ANI/DNIS and Calling Party Disconnect Switch A ON Switch B OFF Switch C ON This option provides a loop-start interface between the AB2 and the PBX for voice mail/phone applications. E&M wink-start signaling and per-channel ringback tones are sent to the T1 line. Ringing voltage is applied immediately after incoming seizure. The 200 ms outgoing wink “proceed-to-send” signal is not sent to the T1 network until 800 ms after FXS ringing voltage has been tripped (answered). Thus, the voice mail or PBX DTMF or MF register has at least one second to be attached to the line after closing the loop. The network proceeds to automatically send four to ten ANI or DNIS digits. User also receives a two-second Tip Open condition (loop current turns off) at the FXS-ID when the network releases seizure (the far-end call hangs up). Battery feed from the FXS-ID returns to normal idle (tip grounded) after the two-second disconnect. This feature is similar to local telephone service Calling Party Disconnect (CPD), provided by some Central Office equipment for answering machines and PBXs that are equipped to detect loss of loop current on their line interfaces. This loss of loop current informs the equipment to disconnect the call. 8.6.1.7 Option 6. Wink-Start to Ground-Start Conversion with ANI/DNIS Switch A OFF Switch B ON Switch C ON This option provides a ground-start interface between the AB2 and the PBX for voice mail/phone applications. E&M wink-start signaling and per-channel ringback tones are provided to the T1 line. Ringing voltage is applied immediately after incoming seizure. The 200-ms outgoing wink “proceed-to-send” signal is not sent to the T1 network until 800 ms after FXS ringing voltage has been tripped (answered). Thus, the voice mail or PBX DTMF or MF register has at least one second to be attached to the line after closing the loop. The network proceeds to automatically send 4 to 10 ANI or DNIS digits. 8.6.1.8 Option 7. Customized Signaling Switch A ON Switch B ON Switch C ON 9/24/01 8-9 FXS-ID Configuration ! Caution: If you use this setting when no customized signaling has been installed, all back plate LEDs turn a steady RED and normal operation of the FXS-ID voice card is interrupted. Upon request, Carrier Access will provide customized FX signaling options that can include any of the aforementioned options plus others, including answer supervision wink signaling. Answer Supervision Wink Signaling Answer supervision wink signaling takes the form of a 200-ms tip-open condition (loop current turns off) from the Access Bank II - SNMP to the voice-mail or phone system when the far end goes off hook (answers the call). Battery feed from the FXS-ID returns to normal (tip grounded) after the 200-ms disconnect. This feature is useful if the calling party switch needs to know when the far end has answered the call. 8.6.2 TP Busy/Idle Switch ON Idle OFF Busy Use this switch to select whether the FXS tip-ground relays will be closed (busy) or open (idle) during trunk processing. (Trunk processing occurs when the T1 line is in an alarm or reset state.) The Busy position (OFF) causes the tip-ground relays to be closed during a T1 alarm or reset period. The Idle position ON) causes the tip-ground relays to be open during a T1 alarm or reset period. Note: The Busy position (OFF) is recommended for loop-start or ground-start applications where the attached PBX has the ability to re-route calls to different trunks when the T1 line is down. 8.7 FXS Voice Channel Monitoring and Testing The channel status LEDs on the back plate of the Access Bank II - SNMP allow you to monitor the status of the individual FXS voice lines. Operation of these LEDs is summarized in Figure 8-4. 8-10 9/24/01 FXS Voice Channel Monitoring and Testing The channel test switches on the FXS-ID back plate can be used to send a 4 second continuous ringing voltage to the tip and ring pair of each FXS voice channel. You can check the operation of an individual voice channel by attaching a test telephone to the Tip and Ring pair of a particular channel at the punchdown block or RJ-11 Harmonica, then switching ON the appropriate channel test switch to test that channel. Figure 8-4: FXS-ID Back Plate Controls and LED Indicators 8.7.1 FXS Backplate Switches Channel Test (12 per FXS card) - Sends four seconds of ringing to voice channel and four seconds of ringback to the T1 channel. After ringing, it will busy out the T1 channel and the voice channel. TP Busy/Idle (1 per FXS card) - selects busy or idle on tip-ground relays during trunk processing. 8.7.2 FXS Backplate LEDs Table 8-3 LED State Condition OFF Idle state (FXS ground start, all E&M settings GREEN Idle stae (normal FXS loop-start operation): Incoming seixure (ground start operaion or E&M conversion) YELLOW Call in progress RED Outgoing line seizure All LEDs YELLOW S AB2 in trunk processing All LEDs flash RED Unsupported signaling option selected 9/24/01 8-11 FXS-ID Configuration 8.7.3 “Busying Out” Individual FXS Channels Switching a channel test switch to the ON position has three results on the selected FXS channel: 1. To confirm individual channel circuit integrity, 4 seconds of ringing voltage are sent to the Tip and Ring pair. The Tip is then grounded until the channel test switch is turned to the OFF position (to the right). ! Warning: Four seconds of ringing voltage (85 V) will be present at the Tip and Ring pair of the FXS channel-under-test until the test telephone is picked up to trip the ringing. Requirement: A test telephone connected to the punch down block or RJ-11 Harmonica should ring for 4 seconds. 2. As an aid to network technicians troubleshooting audio problems, 4 seconds of ringback tone are also sent toward the T1 network. 3. After the 4 seconds of ringback tone, the FXS channel will “busy out” toward the T1 network side. Note: Each channel test switch can provide ringing during Trunk Processing (or even when the T1 line is disconnected). 8.7.4 Self Test Loopbacks During Self-Test, switching a channel test switch to the ON position has the following result: The affected FXS channel receives 4 seconds of ringing voltage (85 V) and the LED for that particular channel turns RED. This allows a technician to ring the telephone and verify audio tone when it is answered. Note: During Self Test, a RED channel LED may come on, but does not indicate a problem. ! 8-12 9/24/01 FXS Voice Channel Monitoring and Testing Warning: The four-second applied ring voltage (85V) can constitute a dangerous shock hazard, and can damage attached low-impedance equipment. 9/24/01 8-13 FXS-ID Configuration 8-14 9/24/01 Chapter 9 Battery Reversal FXS & Dial Pulse Origination Card Contents of This Chapter: About This Chapter .................................... 1 Description of the BRFXS/DPO Card ........ 2 Overview of Operation ............................... 2 BRFXS/DPO Applications .......................... 3 Setting the Transmit and Receive Levels .. 4 Battery Reversal FXS Loop-Start .............. 8 Dial Pulse Origination (DPO) ..................... 8 BRFXS/DPO Voice Ch Monitoring & Testing 8 Busying Out BRFXS/DPO Channels ......... 8 Self Test Loopbacks................................. 9 9.1 About This Chapter This chapter describes how to configure the Access Bank II Battery Reversal Foreign Exchange Station and Dial Pulse Origination (BRFXS/DPO) 12-channel voice card for connection to T1 public network services and provides instructions for: • Setting Transmit and Receive Levels • Setting the FXS with battery reversal and DPO • Performing Voice Channel Monitoring and Testing 9.2 Description of the BRFXS/DPO Card The BRFXS/DPO 12-channel voice card can be configured to operate either as a battery reversal FXS card or as a Dial Pulse Origination (DPO) card. In the battery reversal mode, the BRFXS/DPO 9/24/01 9-15 Battery Reversal FXS & Dial Pulse Origination Card provides twelve 2-wire CPE analog loop-start connections to the digital T1 line using the same method used by the FXS voice card, only with the addition of Tip/Ring battery reversal. The FXS interface reverses the polarity of the battery feed towards the customer premise equipment (CPE) in response to the signaling bits coming from the T1 line. Various PBX systems require battery reversal to signal the start of billing, and in certain telephony environments it is needed to provide Line Side Answer Supervision (LSAS). One important application for battery reversal occurs in International Call Back, which allows international callers dialing the US to avoid more expensive inbound rates by taking advantage of cheaper US outbound long distance rates. Dial Pulse Origination (DPO) is the functional complement to Dial Pulse Termination (DPT) provided by the FXO/DPT voice card. Used in conjunction, the DPO and DPT cards are used mainly for origination and termination of Direct Inward Dial (DID) circuits. The BRFXS/DPO is a 7.8” by 13.16” daughter card designed to slide into the back of the Access Bank II along rails that guide a 64-pin DIN connector to mate with a matched connector on the internal ABI Controller. The card receives the T1 signaling, tip and ring pairs, control logic and power from the Controller card through this connector. The back plate of the card has 12 channel status LEDs and one 4-position DIP switch for selecting between battery reversal FXS loop-start and Dial Pulse Originating (DPO) modes of operation. Furthermore, the back plate also contains 12 test switches that can be used to “busy out” each channel individually. On the BRFXS/DPO card itself, each individual channel has a 6-position DIP switch for setting transmit and receive line attenuation. 9.3 Overview of Operation The reversible-battery FXS channel card is designed to provide twelve 2-wire analog interfaces to the digital T1 (DS1) line. Currently, the analog loops (also called CPE loops in this document) must always be loop-start. One of the main features of the analog interface is that the polarity of the battery feed towards the customer-premise equipment (CPE) can be reversed in response to the signaling bits coming from the T1 line. 9-16 • The basic operation is selected by setting Switch A off so that no ringing voltage is applied towards the CPE. If desired, Switch B can be turned on to give a cadenced (2second/4-second) ringback tone to the T1 line during incoming calls. The battery to the CPE loop will be reversed to indicate an incoming call. The battery will return to forward polarity again when the call has ended. • Also included in this channel card is a setting to provide cadenced ringing voltage (if needed by other customer-premise equipment). This option is enabled by setting Switch A on so that cadenced ringing voltage will be applied to the CPE loop during an incoming call. The battery is reversed during this time. If desired, Switch B can be turned on to give a cadenced (2-second/4-second) ringback tone to the T1 line during incoming calls, that is synchronized to the ringing voltage present on the loop. 9/24/01 BRFXS/DPO Applications Note: During a two-way call, the CPE -loop battery is reversed. To disconnect the call either the CPE loop current ceases or the network sends A/B bits = 0/0. The reversed state of the CPE loop, however, will be maintained until the network terminates (releases) the call. 9.4 BRFXS/DPO Applications As explained above, the two major applications for the BRFXS/DPO card are FXS with battery reversal “wink” to signal a PBX timer to start billing a call and Dial Pulse Origination (DPO) for transport of Direct Inward Dialing (DID) lines. Refer to Figure 9-1 and Figure 9-2 for pictorial representations of these two applications.

Each analog channel uses a bank of six DIP switches, with three for transmit and three for receive. Operation of each set of three switches in additive. For example, setting switch 1 (-2 dB) and switch 2 (-3 dB) to OFF for any given channel selects a receive loss of -5 dB. The default setting for the transmit level is -3 dB; for the receive level it is -6 dB. The default settings are appropriate for most applications.

Pull out the two card ejector latches simultaneously to release the card from the internal connector, then slide the card carefully out from the rear of the ABI chassis. 3. Set different transmit and receive gain or loss levels (see Figure 9-3 and Table 9-1). 4. Re-insert the BRFXS/DPO voice card, ensuring that the card is positioned correctly in the card rails. 9/24/01 9-19 Battery Reversal FXS & Dial Pulse Origination Card 5.

To enable this option, set Switch A on the 4-position DIP switch to ON so that cadenced ringing voltage is applied to the CPE loop during an incoming call (See Table 9-2). The battery is reversed during this time. If desired, Switch B can be turned ON also to send a cadenced (2-second/ 4-second) ringback tone to the T1 line during incoming calls. 9.7.2 Dial Pulse Origination (DPO) The DPO option is selected by setting Switch A to OFF so that no ringing voltage is applied towards the CPE. If desired, Switch B can be turned ON to give a cadenced (2 second/ 4 second) ringback tone to the T1 line during incoming calls (See Table 9-2). To indicate an incoming call, the battery to the CPE loop is reversed. When the call ends, the battery returns to forward. 9.7.3 BRFXS/DPO Voice Channel Monitoring and Testing The channel status LEDs on the back plate of the Access Bank II allow you to monitor the individual BRFXS/DPO voice lines. The meaning of these LEDs is summarized above in Figure 9-4. The channel test switches on the BRFXS/DPO back plate can be used to apply reverse battery to the CPE loop and send A/B bits forced to 1/1 toward the T1 network. If Switch A is ON, 4 seconds of continuous ringing voltage (85 V) are sent to the tip and ring pair of each BRFXS/DPO voice channel. In this case, you can check the operation of an individual voice channel by attaching a test telephone to the Tip and Ring pair of that particular channel at the punchdown block or RJ-11 Harmonica, then switching ON the appropriate channel test switch to test that channel. If Switch B is ON, 4 seconds of continuous ringback tone is also sent to the T1 network. 9.8 Busying Out Individual BRFXS/DPO Channels If Switch A and Switch B are both ON, setting a channel test switch to ON has four results on the selected channel: 1. Reverse battery is applied to the CPE loop and the A/B signaling bits sent to the network are forced to 1/1. 2. To confirm individual channel circuit integrity, 4 seconds of continuous ringing voltage are sent to the Tip and Ring pair. The Tip is then grounded until the channel test switch is turned to the OFF position (to the right). 9-22 9/24/01 Self Test Loopbacks ! Danger: Four seconds of continuous ringing voltage (85 V) will be present at the Tip and Ring pair of the channel-under-test until the test telephone is picked up to trip the ringing. Requirement: A test telephone connected to the punch down block or RJ-11 Harmonica should ring for 4 seconds. 3. As an aid to network technicians troubleshooting audio problems, 4 seconds of continuous ringback tone are also sent toward the T1 network. 4. After the 4 seconds of continuous ringback tone, the FXS channel will “busy out” toward the T1 network side. Note: Each channel test switch can provide ringing during Trunk Processing (or even when the T1 line is disconnected). 9.9 Self Test Loopbacks If a Self-Test is in progress and Switch A is ON, setting a channel test switch to the ON position should have the following result: The affected channel receives 4 seconds of continuous ringing voltage (85 V) and the LED for that particular channel turns RED. This allows a technician to ring the telephone and verify audio tone when it is answered. Note: During Self Test, a RED channel LED may come on, but does not indicate a problem. 9/24/01 9-23 Battery Reversal FXS & Dial Pulse Origination Card 9-24 9/24/01 Chapter 10 12-Channel FXO & Dial Pulse Termination Card Contents of This Chapter: About This Chapter .................................... 1 Description of the FXO Card ...................... 1 Termination Options .................................. 2 Foreign Exchange Office Termination ....... 2 Dial Pulse Termination (DPT) .................... 3 Channel Attenuation Options ..................... 4 10.1 About This Chapter This chapter describes the 12-Channel Foreign Exchange Office (FXO) and Dial Pulse Termination (DPT) card used in the Access Bank II - SNMP, and provides information for configuring the card. 10.2 Description of the FXO Card The FXO/DPT 12-channel analog card is an “office end” telephone line voice card designed specifically as an interface for Carrier Access Corporation’s family of Access Bank II - SNMP T1 Voice and Data Multiplexers, which are FCC-approved digital Channel Banks and Channel Service Unit/ Data Service Units (CSU /DSUs) for attachment of customer premise telecommunications equipment to public network T1 (DS1) services. The FXO/DPT card provides an interface between the Tip/Ring pair and T1 line for each of the channels on the FXO/DPT to provide FXO and DPT operation.The “rear” end of the FXO/DPT card (opposite the connector to the LIU board in the front of the Access Bank) has 12-channel status LEDs and one 4-pin DIP switch used to select whether the card uses 9/24/01 10-1 12-Channel FXO & Dial Pulse Termination Card FXO or DPT termination. Also on the card, each individual channel has a two position switch for the selection of ground start or loop start (see Figure 9-3) and a 6-section DIP switch to control the line attenuation (see Channel Attenuation Options). 10.3 Termination Options The FXO/DPT card can be configured for use as either an FXO or DPT interface card. Further, FXO offers both ground start (GS) and loop start (LS) modes of operation. These options require the setting of one switch per channel (12 per card) and one 4-position Dual Inline Package (DIP) switch per card (see Table 10-1, and Figure 9-3). Note that in the table, a 1 indicates the switch is on, while a 0 indicates the switch is off. The slide switch on the 12-channel analog card for each channel indicates whether that channel is set to GS or LS mode. The DIP switch determines whether the card will use FXO or DPT termination. Note: When DPT is selected, the large slide switches for each channel must all be set to LS. However, when FXO termination is chosen, either LS or GS can be selected for each channel.

The FXO acts as a sink for a battery source, detects ringing, provides outgoing seizure, provides and interprets A/B bit signaling to and from the T1 line, and enables two-way voice frequency transmission. 10-2 9/24/01 Termination Options Incoming PBX FXO T1 FXS CO Outgoing Telephone Telephone Fax Fax Figure 10-1: FXO Operation ________________________________________________________________________________ Direct Inward Dialing (DID) PBX CO T1 *Battery Reversal FXS/DPO 12Channel Analog Card Calling Party Called Party's Direct Extension Figure 10-2: DPT Operation 10.3.2 Dial Pulse Termination (DPT) In DPT mode, the FXO/DPT offers near end termination for one-way Direct Inward Dial (DID). Twoway DID is provided by CAC’s 4 wire E&M interface. The DPT card interprets T1 signaling bits to: • provide incoming seizure • act as a current sink for a PBX -48V battery source • establish an audio path 9/24/01 10-3 12-Channel FXO & Dial Pulse Termination Card • detect battery reversal from the PBX for call progress and confirmation of call completion. 10.3.3 Channel Attenuation Options Each of the 12 channels can be configured to attenuate both the transmit and receive audio signal. Each channel has a 6-position dip switch; three positions for transmit attenuation and three positions for receive attenuation. The switch positions apply different values of attenuation, and are additive (if more than one switch is set to apply attenuation for a specific channel, the attenuation value for the channel is the sum of those switches). The loss is measured in decibels (dB). Note that a 3dB loss implies the average power is reduced by 50%. The following table shows the values of attenuation applied for each switch position. Note: Attenuation is applied when the switch is in the OFF position, and is removed when the switch is in the ON position. Table 10-2: Transmit and Receive Attenuation Switch Values Transmit Switch Position Loss Receive Switch Position Loss 1 2 3 4 5 6 On 0 dB 0 dB 0 dB 0 dB 0 dB 0 dB Off -2 dB -3 dB -4 dB -2 dB -3 dB -4 dB Switch Setting !

Also, cable information and specifications are provided at the end of this section. 11.2 4-Wire E&M/TO Voice Card 11.2.1 Functional Description The 4-wire E&M/Transmission Only voice card delivers 12 analog channels for connecting to private line circuits, such as carrier PBX tie lines and 4-wire modems often found in utility, cellular, and met- 9/24/01 11-1 4-Wire E&M/TO Configuration ropolitan area networks. Each of the twelve E&M channels can be individually configurted to support Signaling Types I, II, IV or V, using up to 4 signaling and transmission pairs per channel (E/M, SG/ SB, T/R, and T1/R1). This card can be configured to function as Channel Equipment (normal multiplexer mode) or as Switching Equipment for back-to-back Tandem applications sometimes referred to as Reverse E&M or Pulse Link Repeater (PLR). 11.2.2 Physical Description Like the FXS and FXO/DPT voice cards, the 4-wire E&M/TO is a 7.8” by 13.16” daughter card that slides into the back of the Access Bank II - SNMP (AB2 - SNMP) along rails that guide a 64-pin DIN connector to mate with a matched connector on the internal ABI Controller. The E&M/TO card receives T1 signaling, control logic, and -48 Vdc power through this connector from the Controller card. Because the RJ-21X Amphenol Telco connector on the ABI front control panel fails to provide enough wiring leads, it is bypassed through a 96-pin E&M signaling line connector attached on the opposite end of the card. The E&M signaling lines (E, SG, M, SB, T, R, T1 and R1) are connected to this high-density 96-pin DIN connector. A bank of 12 channel status LEDs are located next to the E&M signaling line connector on the ABI back plate. Each channel has jumpers that allow the channel to be configured for E&M Types I, II, IV and V signaling. Each channel also has a 10-position DIP switch that allows the receive and transmit attenuation to be individually set from -22 dB to +10 dB. There is also a 4-position DIP switch located next to the processor for setting regular or clear channel E&M signaling types and selecting busy or idle during carrier failure. 11.3 Typical Applications The major applications for the 4-wire E&M/TO voice card are E&M Tie Lines operating in either Normal or Tandem mode. This interface also supports two-way Direct Inward Dial (DID) applications. See Figure 11-1 and Figure 11-2 below for pictorial representations of these typical applications. 11-2 9/24/01 E&M Signaling Conventions 4-Wire E&M TO Mode Dedicated Transmission Only Modem for Data T1 Network Connection Up to 24 E&M or TO Interfaces in 12 Channel Increments Public or Private Network Access Bank I Stations Analog PBX 4-Wire E&M Normal Mode Figure 11-1: Normal Mode E&M Termination Carrier Network T1 PBX T1 Access Bank I Access Bank I 4-Wire E&M Tandem Mode 4-Wire E&M Tandem Mode Radio or Microwave Transceiver Radio or MicroWave tower Radio or MicroWave tower Radio or Microwave Transceiver Figure 11-2: Tandem Mode E&M Access to Leased Lines or Carriers 11.4 E&M Signaling Conventions According to E&M signaling conventions, switching equipment always originates signaling on the M-lead (the “mouth” sending toward the transmission line). The E-lead of the switching equipment 9/24/01 11-3 4-Wire E&M/TO Configuration interface incorporates a signaling current detector (the “ear” listening to the line). The multiplexed or carrier channel equipment always originates signaling on the E-lead coming from the transmission line. The signaling current detector is found on the M-lead going toward the transmission line. The 4-wire E&M/TO voice card can be optioned to operate either as channel equipment or switching equipment. Since the Access Bank II - SNMP typically operates as a voice and data multiplexer, the card is usually configured as channel equipment. This is referred to as tandem operation because the card operates in tandem (i.e. back-to-back) with another transmission device. Table 11-1 lists the generic functions performed by the Detector/Detector Return and Driver/Driver Return when the 4-wire E&M card is configured to operate as Channel Equipment or Switching Equipment.

Because the signaling types are configured for each channel individually, different E&M types may be mixed on the same card. The entire card, however, must operate in either Normal or Tandem mode, which is determined by the signaling cable used (Section 11.7, Normal and Tandem Cables). Table 11-2 (which is also printed on the 4wire E&M back plate) shows the proper jumper connections for each signaling type and mode. Table 11-2: Jumper Connections by Type and Mode E&M Type Jumper Placement Mode J1 J2 J3 1 Normal 3-4 5 8-9 1 Tandem 1-2 5 10-11 2 Normal 3-4 6 7-8 2 Tandem 1-2 6 7-8 4 Normal 1-2 6 7-8 4 Tandem 1-2 6 7-8 5 Normal 1-2 5 8-9 5 Tandem 1-2 5 8-9 The jumpers are blocks that make several connections simultaneously. The entire block is moved 11-6 9/24/01 Detector Configuration between the positions indicated above. This makes configuration easier by changing several connections with one move. The jumper pins are on 0.1” x 0.2” centers, making it impossible for the user to accidentally turn the jumper 90 degrees and short -48V to ground. Figure 11-7 shows the jumpers as they appear on the 4-wire E&M/TO card. Figure 11-7 also shows each of the eight possible signaling combinations as complete channel setups. Note: The jumpers do not change the actual interface pin assignments for the E&M signaling line connector. The detector and driver functions always stay on the same pinouts. 11.6 Detector Configuration Jumper 1 is used to select options for configuring E&M signaling types I, II, IV and V. This jumper connects the detector to -48 Vdc or ground. It is also used to connect the Detector Return to -48 Vdc or ground. An on-hook signal from the far-end equipment does not cause current to flow through the detector. When the far-end equipment applies an off-hook signal, current flows in the detector, causing the detector to be grounded. The processor receives this information and sends E&M signaling bits to the T1 line. The table below summarizes the signaling bits sent for both detector states: E&M V1.1 1 11 Type 5 Tandem Type 4 Tandem Type 4 Normal Type 2 Tandem Type 2 Normal Type 1 Tandem Type 5 Normal Type 1 Normal 11 1 Figure 11-7: 4-Wire E&M Signaling Options 9/24/01 11-7 4-Wire E&M/TO Configuration Table 11-3: E&M T1 Signaling Detector XMT Signaling Bits A B Off 0 0 On 1 1 RCV Signaling Bits A B Driver 0 * On-Hook 1 * Off-Hook *Don’t care (0 or 1) 11.7 Normal and Tandem Cables Individual E&M/TO voice cards require the purchase of the Normal mode or Tandem mode cables listed below in Table 11-4. The type of cable used with the signaling line connector determines whether all twelve channels of that card operate only in that mode. Physically, the Normal and Tandem cables have one 96-pin DIN connector that plugs into the E&M card. The 96-pin DIN connector has two 50 conductor, 24 AWG cables leading to two 50-pin Telco connectors. The Telco connectors use standard RJ-2HX pinouts for 4-wire E&M, providing six channels per connector (twelve channels per card). Figure 11-8 and Figure 11-9 show the 4-wire E&M/TO cables.

This switch is located at the front of the circuit board next to the 64-pin DIN connector. 11-8 9/24/01 TP Busy/Idle Switch Table 11-5: 4-Position DIP Switch Settings Switch Number ON OFF 1 N/A Normal E&M 2 N/A N/A 3 N/A N/A 4 TP Idle TP Busy 11.9 TP Busy/Idle Switch Use switch 4 to select whether the tip-ground relays are closed (busy) or open (idle) during trunk processing. (Trunk processing occurs when the T1 line is in an alarm or reset state.) The Busy position (OFF) causes the tip-ground relays to be closed during a T1 alarm or reset period. The Idle position (ON) causes the tip-ground relays to be open during a T1 alarm or reset period. 11.10 Setting Transmit and Receive Gain The transmit (analog-to-digital) and the receive (digital-to-analog) gain for each voice channel can be set independently using twelve 10-position DIP switches on top of the 4-wire E&M card circuit board. Each analog channel uses a bank of ten DIP switches, with five for transmit and five for receive. The gain from each switch is additive, with switches 1-5 providing transmit (analog-to-digital) gain of 1, 2, 4, 8 and 16 dB, respectively. Switches 6-10 set receive (digital-to-analog) gains of 1, 2, 4, 8, and 16 dB, respectively. With all five switches off, the gain is -21dB. Because the gain from the switches is additive, any gain level between -21dB and 10dB is possible. The digital transmission level is limited by the codec to a maximum of 3.17dBm0. The gain stages may be set to apply up to 10dB of gain; however, the maximum level of the codec must not be exceeded or distortion will result. The analog transmission level may be set to a maximum 9.5dBm before distortion begins to occur. 11.11 Transmit (Analog-to-Digital) Gain A transformer provides the analog input (T, R) from the 4-wire voice connections to the Access Bank II - SNMP. The gain from each switch on the 10-position DIP switch is additive, with switches 1-5 providing gain of 1, 2, 4, 8 and 16 dB, respectively. To calculate the T1 transmit level, use the following formula: T1 level = Analog Input level + åGain Switches - 21 The following is an example of setting transmit gain: Suppose the analog input level is at +3dBm. With all switches off, the level at the T1 line is +3dBm 21db = -18dBm0. To set a 0dBm0 level at the T1 line, switches 2 and 5 (gains 2dB, and 16dB) must be turned on. The level at the T1 line is then: 9/24/01 11-9 4-Wire E&M/TO Configuration T1 level = 3dBm + 16dB + 2dB - 21dB = 0dBm0 11.12 Receive (Digital-to-Analog) Gain To calculate the receive level on the T1, R1 pair, use the following formula: T1/R1 level = T1 level +åGain Switches -21dB The following is an example of setting receive gain: Suppose the T1 input level to codec is at -1dBm0. With all switches off, the output at the T1, R1 pair is -1dBm -21db = -22dBm. To set a 4-wire transmission level of 0dBm, switches 7, 9 and 10 (gains 2dB, 8dB, and 16dB) must be turned on. The level at the T1, R1 pair is then: T1/R1 level = -1dBm0 + 2dB + 8dB +16dB -21dB = 0dBm. 11.13 E&M Voice Channel Monitoring 11.13.1 Call Progress LED Indicators A bank of LEDs on the ABI back plate are used to monitor the status of incoming or outgoing calls on each of the twelve voice channels. When viewing the LED bank, channel 1 corresponds to the LED in the top left hand corner. Other channels are arranged left to right, row by row (like reading a book), so channel 12 is in the bottom right corner. The meaning of the states of these 12 LEDs are summarized in Table 11-6.

About This Chapter This chapter provides instructions for performing: • Self Test Loopbacks. • Network Loopbacks. • Disabling external alarms. • Fault isolation procedures for troubleshooting problems encountered while operating the Access Bank II - SNMP. 12.2 Diagnostic Switches The Access Bank II - SNMP System Setup and T1 Span Setup DIP switches on the Control Panel include settings for running the self test loopbacks, enabling network loopbacks, and enabling alarm cut-off. 9/24/01 12-1 Note: These tests as well as additional test functions can be performed using the MS Windows-based Remote Monitor software. For directions on performing Self Test loopbacks and tone transmission, enabling network loopbacks, and activating automatic Alarm Cut-Off (ACO) via the software, see the separate Remote Monitor User’s Guide. 12.3 Self Test 1 and 2 ! Caution: Because Self Test is a service-disrupting procedure. Disconnect all attached telephones prior to initiating Self Test. 12.3.1 Local Mode: OFF = No Test Tone, ON = Ringback Tone In the Local mode, when the Self Test DIP switch 1 or 2 is set to ON and the Trunk Processing Busy/ Idle switch on each equipped FX voice card is set to Busy, the T1 output signal from T1 Span 1 or Span 2 is disconnected from the network and looped back into the appropriate T1 receiver. See Figure 9-1. The specified T1 signal is checked internally for framing, line coding, and bipolar violations (BPV) errors, which verifies proper operation of the Controller card. The T1 signal from the specified span is isolated at the T1 line connection point through relay contacts to ensure that all T1 transmit and receive circuits are tested. The Controller then runs a card level test and injects an internally generated ringback dual tone (440 Hz +480 Hz) into all attached PCM codec channels on the T1 span specified. This allows you to verify operation of the voice channels at the punchdown block or RJ-11 Harmonica with a telephone “buttinsky” set. For normal Access Bank II - SNMP operation, the Self Test switch must always be left in the factory default OFF position. The self test takes up to 16 seconds. The T1 Test 1 or 2 LED turns red during the self test sequence. When the self test is complete, the LED should turn green. (If the Test LED remains red for longer than 16 seconds, the unit has failed the self test.) For the self test to be valid, the Access Bank II SNMP must be equipped with the Controller card and at least one voice card. To start Self Test 1 or 2 in the Local mode: 1. Locate the Self Test 1 or Self Test 2 switch on the 10-position T1 Span Setup DIP switch on the Access Bank II - SNMP Control Panel, and set it to the Self Test position (ON). 12-2 9/24/01 Self Test Fault Indications 2. Verify that T1 Test 1 or T1 Test 2 LED turns green after approximately 16 seconds. 12.3.2 Card Self Test At the start of the self test sequence, when the Controller asserts the self test bit toward the voice card, the following events occur on a per channel basis: • The voice card reads from the Controller and sees the self test flag at logic 1 (active). • The received A/B signaling bits are not processed since the signaling state machine is skipped in software. • The outputs of the signaling state machine are forced to: Table 12-1: Card Self Test Signaling States Signaling Ringing voltage Tip Lead Quiet Channel Ringback A bit to network B bit to network T1 Test 1 LED T1 Test 2 LED Output OFF GROUNDED OFF ON ZERO ONE RED (failure) RED (failure) 12.4 Self Test Fault Indications 12.4.1 Voice Channel LED is RED during Self Test During Self-Test, a red channel LED may come on, but does not indicate a problem. 12.4.2 No Test Tone During a Self Test If no ringback tone is present at the drop for a particular voice channel during a self test, there may be an open or broken pair in the voice cable. If no test tone is present on any channel during a self test, the voice cable may be disconnected. To correct the problem: 1. Check the voice cable for a loose connection. 2. Check the voice cable for a broken/open pair. 3. If no test tone is present on a set of 12 channels during a self test, the associated voice card may be faulty. Try replacing the voice card. 9/24/01 12-3 12.4.3 Remote Mode: Ringback Tone or 1 Digital Milliwatt When the Access Bank II - SNMP is powered up in Remote mode, the tone sent during the Self Test can consist either of the same Ringback dual tone (440 Hz +480 Hz) sent in the Local Mode or a standard 1 kHz digital milliwatt test signal. In Remote mode, Ringback tone is the default setting. 12.5 1 kHz Digital Milliwatt Test Signal The 1 kHz digital milliwatt signal test is used to check proper DS0 channel alignment and for isolating transmission failure problems between the Access Bank II - SNMP and connected switching equipment. As specified in AT&T PUB 43801, the transmission of the following repetitive eight byte pattern (1E/ 0B/0B/1E/9E/8B/8B/9E) in a given channel should be decoded in a properly aligned receiving terminal as a 0dBm0, 1 kHz sine wave signal: Table 12-2: Standard Digital Milliwatt Signal Digit No. 1 0 0 0 0 1 1 1 1 2 0 0 0 0 0 0 0 0 3 0 0 0 0 0 0 0 0 4 1 0 0 1 1 0 0 1 5 1 1 1 1 1 1 1 1 6 1 0 0 1 1 0 0 1 7 1 1 1 1 1 1 1 1 8 0 1 1 0 0 1 1 0 12.6 Network Loopback 1 and 2 12.6.1 Local Mode: No Network Loopback or Network Loopback Enabled In the Local mode, setting Network Loopback 1 or 2 switch to ON causes the T1 signal received from T1 network interface 1 or 2 to be looped back toward T1 line 1 or 2 by connecting the T1 receiver to the T1 transmitter before the framer chip. See Figure 9-2. T1 signals are sent back to the network exactly as they were received. No pulse stuffing, BPV correction, or framing is performed that would corrupt T1 test patterns (such as a QRSS) received from the far end. Channel interfaces are held in the Trunk Processing state when the Network Loopback switch is activated. The T1 Test 1 or T1 Test 2 LED on the Control Panel shows continuous yellow. All voice channel operations are suspended and the channel status LED indicators on the back plate show continuous yellow. 12-4 9/24/01 Remote Mode: Remote T1 Line or Payload Loopbacks 12.7 Remote Mode: Remote T1 Line or Payload Loopbacks In Remote mode, if the T1 line is ANSI T1.403 ESF formatted and Network Loopback detect and ESF ANSI detect both has been enabled, the two types of loopback codes the Access Bank II - SNMP can be configured to detect are Remote T1 Line and Remote Payload Loopback. The default setting in Remote mode is Remote T1 Line Loopback. 12.8 ANSI T1.403 Remote T1 LLB In a Remote T1 Line Loopback, upon receipt of a bit-oriented loopup command message consisting of 0000111011111111 repeated at least 10 times toward the Access Bank II - SNMP in the Facility Data Link (FDL), data recovered off the T1 line is transmitted back onto that T1 span specified with no changes in bit sequence integrity, framing format or removal of BPVs. The Access Bank II SNMP should maintain the Remote LLB when it receives a loopback retention signal of 0010101011111111 sent continuously from the far-end. The loopback retention code word should be present in the returned T1 signal. The Remote T1 LLB is released upon receipt of the bit-oriented command message consisting of 0011100011111111, repeated at least 10 time in the FDL toward the Access Bank II - SNMP. See ANSI T1.403-1995, Section 9.3.2.2-3 and Table 4. 12.8.1 ANSI T1.403 Remote Payload Loopback In a Remote Payload loopback, upon receipt of a bit-oriented loopup command message consisting of 0001010011111111 repeated at least 10 times toward the Access Bank II - SNMP in the FDL, the payload of the received T1 signal (192 information bits of a DS1 frame) is returned with no changes in bit sequence integrity and newly generated ESF framing. The T1 Framer will correct the BPVs in the 192 bits of payload data and re-transmit the data. The FPS framing pattern, CRC-6 calculation, and the FDL bits are not looped back, but are instead, reinserted by the Framer. The remote PLB is released upon receipt of the bit-oriented command message consisting of 0011001011111111, repeated at least 10 times in the FDL. 12.9 Illustrations of Loops and Self-Tests The following illustrations show how the loop-back tests and self-tests work.

Setting this switch to the Alarm Cut-Off position (ON) opens the alarm relay contacts (150 Vrms, 150 mA maximum load) that close when the Access Bank II - SNMP enters an alarm state. Table 9-3 defines the pin functions on the 50-pin Tip & Ring jack.

Fault symptoms are organized into three groups: 12-14 • Control Panel LED indications (system, T1 or V.35 faults) • Back Plate LED indications (voice circuit faults) • Other fault indications 9/24/01 Fault Isolation Procedures Table 12-7: Control Panel LED Indications Symptom All LED test and status indicators are OFF. T1 Span 1 or 2 LED is RED. Corrective Action Indicates a loss of power or excessive voltage to the Access Bank II - SNMP. To correct the problem: 1 Verify that the Power Conversion Cube is plugged into an active AC outlet and the power switch on the power converter is turned on. 2 Check the circuit breaker on the Power Conversion Cube. 3 If you are using an external -48 Vdc power source, check the applied voltage. If the applied voltage is incorrect (e.g., greater than -70 Vdc), disconnect the external voltage source and correct its voltage output level. The Access Bank II - SNMP circuitry will automatically reset. 4 If the problem persists, the Access Bank II SNMP power supply on the Controller card has failed. Replace the Controller card following the procedure given in the Maintenance section. The Access Bank II - SNMP is not receiving a T1 signal from the line indicated. To correct this condition: 1 Check the T1 interface cable at the RJ-48C jack and at the carrier demarcation jack. Ensure that the cable is properly plugged in. If so, go to Step 2. 2 Run a Self Test. If the affected T1 Test LED comes up green, replace the T1 cable. If the problem persists contact the service provider. Table 12-8: Control Panel LED Indications (continued) Symptom T1 Span 1 or 2 LED is YELLOW. Corrective Action . Bipolar Violations (BPVs) are being received from the network. A 1-second flash indicates that at least one BPV was received during a 1second interval. To correct this problem: 1 Verify the T1 Line Code 1 or 2 option selected matches the line coding sent by the carrier. 2 If the Line Code option is set correctly and the problem persists, contact your service provider. 9/24/01 12-15 T1 Test 1 or 2 LED is RED. T1 Test 1 or 2 LED flashes YELLOW. If the T1 Test LEDs remain red for more than 16 seconds after a Self Test is initiated, the Access Bank II - SNMP has failed the Self Test. To correct the problem: 1 Verify that the Controller card and at least one voice card are in place. 2 Power down the Access Bank II - SNMP for 60 seconds, power it up again, and repeat the Self Test. 3 If the Access Bank II - SNMP fails the Self Test again, replace the Controller card using the procedure given in the Maintenance section. The Access Bank II - SNMP is in Network Loopback. If this condition persists, the Access Bank II - SNMP may not have received a loop down code to end the network loopback To clear this condition: 1 Be sure the Network Loopback switch is set to OFF. 2 Set the Self Test switch to the Self Test ON position, then back to OFF. 12.13 Back Plate Indications 12.13.1 Voice Channel LED is RED (during a Self Test) During a Self-Test, a RED voice channel LED may appear, and does not indicate a particular problem. 12.13.2 All Voice Channel LEDs flash RED This usually indicates that an unsupported signaling option has been selected. Reconfigure the FXS card to a supported signaling type. 12.14 Other Fault Indications 12.14.1 No Ringing During a Self Test If no ringing signal is heard at the drop for a particular channel during a Self Test, there may be an open or broken pair in the voice cable. If no ringing signal is heard on any channel during a self test, the voice cable may be disconnected. To correct the problem: 12-16 9/24/01 Access Bank II - SNMP Shuts Down for No Apparent Reason 1. Check the voice cable for a loose connection. 2. Check the voice cable for a broken/open pair. 3. Use Remote Monitor software to run a Self Test Loopback with the Ringback tone. If no ringing tone is heard at the drop, the ringback generator on the Controller card may be faulty. Replace the Controller card using the procedure given in the Maintenance section. 12.15 Access Bank II - SNMP Shuts Down for No Apparent Reason Internal thermal protectors automatically shut down Access Bank II - SNMP operation if the operating temperature rises above 140º F (60º C). To correct this problem: Verify that the Access Bank II - SNMP is properly ventilated to allow for heat dissipation, and reduce the ambient temperature if necessary. The Access Bank II - SNMP resets automatically when the temperature is reduced below 104º F (40 C). 9/24/01 12-17 12-18 9/24/01 About This Chapter Chapter 13 Maintenance Contents of This Chapter: About This Chapter .................................... 1 Replacing a Voice Card ............................. 2 Replacing the Controller Card ................... 3 13.1 About This Chapter This chapter provides procedures for maintaining the Access Bank II - SNMP, including: • “Hot swapping” individual voice cards • Replacing the Controller card All Access Bank II - SNMP circuits are contained on one internal Controller card and two 12-channel voice card(s). The voice cards can be “hot swapped” with the power on, if necessary. However, power must be disconnected before replacing the Controller card. Procedures for replacing the card assemblies are given on the pages that follow. ! Caution: Use proper electrostatic discharge (ESD) procedures when removing and handling the Access Bank II - SNMP Controller and FXS and FXO voice cards. 9/24/01 13-1 13.2 Replacing a Voice Card To replace a voice card while the Access Bank II - SNMP is hot, refer to Figure 13-1, then follow these steps: 1. Release the two thumb screws on the back plate of the Access Bank II - SNMP and remove the plate. 2. On the voice card you wish to remove, lift the card ejector latches to release the card from its internal connector. 3. Carefully slide the card out of the back of the Access Bank II - SNMP. 4. Check the channel attenuation loss and gain option settings on the replacement voice card and verify they are set correctly for your intended application. If necessary, reset the channel attenuation option settings. 5. Ensure that the replacement voice card is positioned correctly in the guide rails, then carefully slide the card into the slot. 6. Press the card ejector latches in towards the card until the 64-pin DIN connector on the card mates with a matching connector on the Controller card. 7. Replace the back plate and tighten the thumbscrews. ! Caution: “Hot swapping” an FXS card will cause all 24 channels to go through Trunk Processing for 16 seconds. All calls will be disconnected and must be dialed again after the Access Bank II - SNMP returns to its normal operating state. 13-2 9/24/01 Replacing the Controller Card Figure 13-1: Accessing the Voice Cards 13.3 Replacing the Controller Card To replace the Access Bank II - SNMP Controller card, follow these steps: 1. Power down the Access Bank II - SNMP. 2. Disconnect power and interface cables 3.

The DIP switches must be set to the remote software control mode in order to use SNMP, CLI, or GUI management terminals. In the local hardware control mode, you can use these DIP switches to perform self-tests for channel alignment, to select basic T1 hardware configuration parameters (AMI/B8ZS, D4/ESF), and to enable detection of standard D4/ESF inband loop codes by the integral CSUs. 9/24/01 14-1 14.3 SNMP Management The Access Bank II SNMP provides: • Built-in SNMPv2 Agent software providing network statistics, information retrieval and update, trap thresholds, and automatic transmission of trap data to Network Management Stations. • Application Support for Simple Network Management Protocol (SNMP) and Telnet, per RFC 1902 through 1907. Management Information Base (MIB), per RFC 1573. • Transport Support for Transport Control Protocol (TCP) and User Datagram Protocol (UDP), per RFC 1213. • Internet Support for Internet Protocol (IP) version 4, Internet Control Message Protocol (ICMP), Address Resolution Protocol (ARP), and Reverse ARP (RARP), per RFC 1213. • Managed Object Support for T1 interfaces, per RFC 1406. Serial RS-232 and V.35 interfaces for SNMPv2, per RFC 1659. 14.3.1 Local and Remote SNMP Management The Access Bank II SNMP provides SNMP management through its Ethernet 10Base-T port. Remote SNMP management is possible over either of the T1 lines within a V.35 user data segment, as shown in Figure 14-1. Remote Control SNMP in data stream V.35 Frame or IP Network T1 Access Bank II SNMP SNMP Manager Router LAN Ethernet 10Base-T Local Control SNMP Manager Figure 14-1: Local and Remote SNMP Management 14.3.2 SNMP Overview SNMP is a complete, but simple, mechanism for network management. It works by exchanging information between a Manager and an Agent. In this case, the Agent is inside the Access Bank II/SNMP. The Manager is a Network Management Station (NMS), which is a computer with SNMP management software such as HP OpenView® or Sun NetManager®. The Agent stores the information in a Management Information Base (MIB), which contains items such as the current status of the network interface, performance statistics, and alarms. In general, SNMP is not concerned with controlling every feature of the many different network objects. However, SNMP is flexible enough that it can support a wide variety of private enterprise 14-2 9/24/01 SNMP Management objects with predefined MIB data structures. The Access Bank II/SNMP uses the Bellcore® standard MIB for T1 interfaces. Manager operations include simple “get” and “set” commands to retrieve and update MIB data in the Agent. Normally, the Manager polls the Agent periodically to check traffic statistics. However, the Manager can also set thresholds for traps. Traps specify network events and conditions for which the Agent automatically sends a Telnet alarm message with trap data back to the Manager. The Access Bank II SNMP Agent’s principle benefits are the proactive management of V.35 and DSX-1 alarms, performance statistics, and line tests. 14.3.3 Protocols The Manager and Agent are software applications. They communicate with each other through several protocol layers (Figure 14-2) that are normally transparent to the user. The Access Bank II/ SNMP uses Ethernet as the physical link between the Manager and Agent. The Ethernet data can, in turn, be carried over either of the T1 lines within a V.35 user data segment. SNMP is an application-level protocol intended to work with the User Datagram Protocol (UDP) and Internet Protocol (IP) suite, which includes BootP, Internet Control Message Protocol (ICMP), Address Resolution Protocol (ARP), and Reverse ARP (RARP). The advantage of UDP is that each message is independent; no network connections are maintained between the Manager and Agent. Manager (many paths are possible) Telnet SNMP TCP ICMP Agent UDP BootP IP ARP RARP Ethernet Figure 14-2: Protocol Hierarchy Used In Access Bank II SNMP 9/24/01 14-3 14.3.4 Management Information Bases The SNMP agent on Access Bank II SNMP supports the following standard MIB object groups: Table 14-1: Supported Management Information Bases MIB RFC RFC1213 Description RFC1406 RFC1573 RFC1659 Definitions of Managed Objects for the DS1 and E1 Interface Types Evolution of the Interfaces Group of MIB-II Definitions of Managed Objects for RS-232-like Hardware Devices using SNMPv2 Management Information Base for Version 2 of the Simple Network Management Protocol (SNMPv2) Management Information Base for Network Management of TCP/IP-based: Internet MIB-II RFC 19021907 14.3.5 Commands The Access Bank II SNMP supports commands for the following operations described in RFC 1902 through 1907. • GetBulkRequest • GetNextRequest • GetRequest • Inform • Report • Response • SNMPv2-Trap • SetRequest 14.3.6 Statistics The Access Bank II SNMP agent maintains statistics for the following network interface and TCP/IP protocols: 14-4 • Ethernet Media Access Control (MAC) • Address Resolution Protocol (ARP) for 10 entries • Internet Control Message Protocol (ICMP) • Internet Protocol (IP) • User Datagram Protocol (UDP) • Simple Network Management Protocol (SNMP) 9/24/01 SNMP Management • T1 interface statistics, per RFC 1406 14.3.7 Traps The Access Bank II SNMP agent supports the following standard SNMPv2 defined traps. In the future, enterprise specific traps will be added. Interpretations of the trap values are: coldStart Trap A coldStart(0) trap signifies that the sending protocol entity is reinitializing itself such that the agent's configuration or the protocol entity implementation may be altered. warmStart Trap A warmStart(1) trap signifies that the sending protocol entity is reinitializing itself such that neither the agent configuration nor the protocol entity implementation is altered. linkDown Trap A linkDown(2) trap signifies that the sending protocol entity recognizes a failure in one of the communication links represented in the agent's configuration. The Trap-PDU of type linkDown contains as the first element of its variable-bindings, the name and value of the ifIndex instance for the affected interface. linkUp Trap A linkUp(3) trap signifies that the sending protocol entity recognizes that one of the communication links represented in the agent's configuration has come up. The Trap-PDU of type linkUp contains as the first element of its variable-bindings, the name and value of the ifIndex instance for the affected interface. authenticationFailure Trap An authenticationFailure(4) trap signifies that the sending protocol entity is the addressee of a protocol message that is not properly authenticated. While implementations of the SNMP must be capable of generating this trap, they must also be capable of suppressing the emission of such traps via an implementation-specific mechanism. egpNeighborLoss Trap not supported enterpriseSpecific Trap A enterpriseSpecific(6) trap signifies that the sending protocol entity recognizes that some enterprise-specific event has occurred. The specific-trap field identifies the particular trap, which occurred. (to be implemented in the future) 9/24/01 14-5 14.3.8 Maintenance The Access Bank II SNMP provides maintenance functions for the following SNMPv2 operations. • Loopback operations: T1 remote line and payload. Loopback operations verify and segment operating network interface circuits. • Fault isolation: BERT QRSS test patterns in conjunction with loopback operations. The user may also employ standard Internet PING function tests to check the connectivity at the IP layer. All features of the Access Bank II SNMP are manageable through the Command Line Interface (CLI) using a VT-100 terminal via the RS-232 port, or using a Telnet terminal session over the Ethernet port. All product configurations specified in RFC1406 and RFC1659 are controllable through SNMP Network Management Stations, with the following exceptions: DSX-1 metallic loopback, bit error pattern generation and detection, and advanced redundancy options. In future software releases, it will be possible to add private enterprise objects that represent information specific to these Carrier Access Corporation product features. 14.4 Command Line Interface (CLI) The Command Line Interface gives the user the most complete management capability. The Command Line Interface is accessible via the 10BaseT Ethernet connection using the Telnet protocol or via the RS-232 management port. 14.4.1 Local and Remote CLI Management The Access Bank II SNMP provides CLI management through its RS-232 and Ethernet 10Base-T ports, as shown in Figure 14-3 and Figure 14-4. For RS-232 CLI management, a cable is connected from the RS-232 port on the Access Bank II SNMP to a PC or laptop computer. You can use a VT-100 terminal emulation program such as Microsoft Hyper Terminal®. CLI can also be used from a remote site by connecting the RS-232 port to a modem and telephone line. For Telnet CLI management, you can use a Telnet TCP/IP communications program to access CLI through the Ethernet management port. Remote Telnet CLI operation is available using Telnet over Ethernet or using inband T1 via the V.35 data port. 14-6 9/24/01 Command Line Interface (CLI) .

The full name for the standard is IEEE 802.3 10Base-T. AIS (Alarm Indication Signal): Also known as a “Blue Alarm Signal” or “All Ones Keep Alive,” an AIS is an unframed all ones bit pattern sent by equipment at the far end to indicate that an alarm condition exists upstream in a circuit leading to the downstream equipment. Keep-alive signals are required by the network facilities to prevent oscillation of the line repeaters which causes interference (i.e. cross-talk and bleeding) within adjacent channels. AMI (Alternate Mark Inversion): An AMI encoded signal is a bipolar pseudo-ternary signal conveying binary digits (bits) in which successive “marks” are normally of alternating, positive and negative, polarity. This is the traditional method of line encoding used with bipolar DS1 (T1) signals. However, use of AMI does not preclude long strings of zeros being sent in the signal entering the public network from the DTE in violation of the pulse density requirements mandated in Part 68 of the FCC Rules and/or AT&T Publication 62411. ANI (Automatic Number Identification): ANI is a service available from the telephone company on certain links that identifies the phone number of the caller to an attached computer telephony system. B8ZS(BINARY 8-ZERO SUBSTITUTION): This line coding scheme is one of the methods used to avoid long strings of zeros in a bipolar DS1 signal entering the network from the DTE. Every string of eight zeros is replaced by a special code (token) for transmission over networks that are sensitive to long strings of zeros. The code contains a pattern of bipolar violations that is identified by the recipient and then removed in the decoding process to recreate the original string of zeros. This particular method of line coding is the evolving standard, but one that is not yet fully supported by all carriers. BIT ERROR RATE (BER): The ratio of bits received in error to total bits transmitted. The time over which this rate is calculated is not inherent to the definition of BER and, therefore, can be separately specified. BERT (BIT ERROR RATE TESTER): A test instrument for performing Bit Error Rate testing on a T1 line. See BER. BLUE ALARM SIGNAL: See AIS. BPV (BIPOLAR VIOLATION): A violation of the T1 bipolar AMI transmission pattern in which succeeding “ones” (pluses) are sent at opposite polarities. A BPV normally indicates a transmission error. However, B8ZS patterns contain bipolar violations, which are not counted as errors. CENTRAL OFFICE (CO): Telephone company facility where subscribers’ lines are joined to switching equipment for connecting other subscribers to each other, locally and long distance. CHANNEL SERVICE UNIT: See DSU/CSU CONNECTION: A connection is a logical linkage between timeslots on a span or between spans. CROSSTALK: Crosstalk occurs when you can hear someone you did not call talking on your telephone line to another person you did not call. You may also only hear half the other conversation (i.e. just one person speaking). There are several technical causes for crosstalk relating to cable placement, shielding and transmission techniques. CUSTOMER PREMISES EQUIPMENT (CPE): Items of telecommunications equipment, such as key systems, PBXs, answering machines, and CSU/DSUs, which reside on the customer’s premises past the network interface. CYCLICAL REDUNDANCY CHECK (CRC): A check sum indicator based on the remainder of a polynomial calculation performed on the transmitted data that is used to verify, with some fixed probability of correctness, whether that data was transmitted. D4 SUPERFRAME (SF) FRAMING FORMAT: The most popular framing format in the T1 environment. Its name stems from the way framing is performed in the D-series of channel banks from AT&T. There are 12 separate 193-bit frames in a superframe. The D4 framing bit is used to identify both the channel and the signaling frame. In D4 framing, signaling for voice channels is carried inband by every channel along with the encoded voice. “Robbed bit signaling” is a technique used in D4 channel banks to convey signaling information. With this technique, the eighth bit (least significant bit) of each of the 24 8-bit timeslots is “robbed” every sixth frame to convey voice related signaling information (on-hook, off-hook, etc.) for each voice channel. DATA SERVICE UNIT: See DSU/CSU DATA TERMINAL EQUIPMENT: See DTE DCE (DATA CIRCUIT-TERMINATING EQUIPMENT): DIRECT INWARD DIALING (DID): The ability for a caller outside a company to call an internal extension without having to pass through an operator or attendant. In large PBX systems, the dialed digits are passed down the line from the Central Office (CO). The PBX then completes the call. DIGITAL ACCESS & CROSS-CONNECT SYSTEM (DACS): A digital switch for routing and switching T1 lines (and individual DS0 channels within T1 lines), among multiple T1 ports. It performs all the functions of a normal switch, except connections are typically set up in advance of a call, not together with a call, as in most, low bandwidth voice-band voice and data communications systems. A DACS is basically a manual T1 switch. The Windows-based Remote Monitor software program can be used to implement DS0 DACS functionality in the Access Bankô II. DIP (DUAL INLINE PACKAGE) SWITCH: A tiny switch attached to a printed circuit board with semipermanent settings that usually requires a ball point pen or small screwdriver to change. There are only two settings - ON or OFF (1 or 0). In the case of the ABII, configurations set by the DIP switches can be modified later through the MS Windows Remote Monitor software installed on a PC. DIRECT OUTWARD DIALING (DOD): The ability to dial directly from an extension without having to go through an operator or attendant. In PBX and hybrid phone systems, you dial 9, listen to a dial tone, and then dial the outside number you want to reach. DNIS (DIRECTORY NUMBER IDENTIFICATION SERVICE): DNIS is a feature of 800 and 900 lines that provides the number of the caller dialed to reach the attached computer telephony system. Using DNIS capabilities, one trunk group can be used to serve multiple applications. The DNIS number can be provided in a number of ways, inband or out-of-band, ISDN or via a separate dedicated data channel. DPO (DIAL PULSE ORIGINATION) CHANNEL UNIT DPT (DIAL PULSE TERMINATING) CHANNEL UNIT DROP & INSERT (D&I): As applied to T1, D&I refers to the process whereby one DS-0 channel is demultiplexed out of the DS-1 synchronous bit stream at one port of a digital channel back and another DS-0 inserted back in. The Windows-based Remote Monitor software program can be used to perform D&I on individual channels between two T1 lines connected to the Access Bankô II. DSU/CSU (DATA SERVICE UNIT/CHANNEL SERVICE UNIT): A device terminating a digital channel on a customer’s premises where it performs line coding, line conditioning and equalization functions while responding to the receipt of loopback codes sent from the Central Office (CO) A DSU/CSU sits between the digital line coming in from the CO and devices such as channel banks or data communications devices. DSX (DIGITAL SYSTEM CROSS-CONNECT frame): A bay or panel to which T1 lines and DS1 circuit packs are wired that permits cross-connections by patch cords and plugs. A DSX panel is used in small office applications where only a few digital trunks are installed. DTE (DATA TERMINAL EQUIPMENT): In the EIA/TIA 232E standard specification, the RS232 interface is connected between the DCE (Data Circuit-Terminating Equipment) and the DTE. The main difference between the DCE and the DTE is the pins two and three are reversed. The ABII uses an RS-232 port for management and asynchronous and synchronous data transmission. DTMF (DUAL TONE MULTIFREQUENCY SIGNALING): A method of signaling in which a combination of two frequencies out of a possible eight are used to transmit numerical address information. The eight possible frequencies are 697 Hz, 770 Hz, 852 Hz, 941 Hz, 1209 Hz, 1336 Hz, 1477 Hz, and 1633 Hz. E&M SIGNALING: A signaling arrangement that uses separate leads, called respectively the E lead and the M lead, for the signaling and voice signals. The M lead (derived from ‘Mouth’) transmits ground or battery to the distant end of the circuit, while incoming signals are received as either a grounded or open condition on the E (derived from ‘Ear’) lead. The E&M tie trunk interface functions as a de facto standard in the PBX - T1 multiplexer Telco environment. ESF (EXTENDED SUPERFRAME FORMAT): FACILITY DATA LINK (FDL): The 4 Kbps channel used to transmit supervisory FOREIGN EXCHANGE CHANNEL UNIT - OFFICE END (FX0) FOREIGN EXCHANGE CHANNEL UNIT - STATION END (FXS) FRAME RELAY ACCESS DEVICE (FRAD): FXSDN (FXS SOFTWARE-DEFINED): LINE INTERFACE UNIT (LIU): Typically, a controller device in a D-type channel bank, such as the CAC Access Bankô II, that incorporates a controller, channel service unit (CSU), ringing generator and power converter on a single card to interface between the T1 network and the analog functions of the channel bank. PBX (PRIVATE BRANCH EXCHANGE): PERFORMANCE REPORT MESSAGE (PRM): PLAR (PRIVATE LINE AUTOMATIC RINGDOWN): A leased voice circuit that connects two single telephone handsets together. Whenever either handset is lifted, the other instrument automatically rings. PSTN (PUBLIC SWITCHED TELEPHONE NETWORK): As used by the ITU-T, PSTN is simply an abbreviation for the local phone company QRSS (QUASI-RANDOM SIGNAL SEQUENCE): A standard test pattern generated by a 20-bit linear feedback shift register used during loopback and BER testing to stress test the continuity and integrity of a T1 circuit by simulating live data traffic. Generates every combination of 20-bit words, repeats every 1,048,575 bits, and suppresses consecutive zeros to no more than 14. Contains high density sequences, low density sequences, and sequences that change from low density to high density and vice versa. RING BACK TONE: An interrupted low tone indicating that the called telephone is ringing. This tone is generated by a device at the Central Office (CO) and may bear no relationship to the sound the phone at the other end is emitting - or not emitting. RING GENERATOR: A component of virtually all phone systems, including the Access Bankô II, that supplies the power to ring the bells inside phones, typically 90 volts AC at 20 Hz. RINGER EQUIVALENCY NUMBER (REN): Part of the FCC certification number approving a telephone terminal product for direct sale to the end user as not doing harm to the network. The REN consists of a number and a letter which indicates the frequency response of that telephone’s ringer. The number indicates the quantity of ringers which ma be connected to a single telephone line and still all ring. The total of RENs of the telephones connected to the one line must not exceed the value 5 or some or all of the ringers may not operate. SCADA (SUPERVISORY CONTROL AND DATA ACQUISITION): SLC96 (SUBSCRIBER LOOP CARRIER 96): A short-haul multiplexer manufactured by AT&T Technologies that enables up to 96 telephone customers to be served on three pairs of wires. SNMP (SIMPLE NETWORK MANAGEMENT PROTOCOL): SNMP is an application layer connection-less protocol, running over UDP (User Datagram Protocol), that functions as TCP’s stack network management protocol between a management station and a SNMP agent resident in a managed device. For managing TCP/IP-based networks, SNMP is the de facto standard. SNMP is designed to implement an automated network-management system for controlling and performance monitoring managed devices such as hosts, bridges, routers, CSU/DSUs, and channel banks in networks and distributed processing systems. SPAN: A span is a logical name for an access port into the Access Bank II. A span carries Voice/Data information to/from the Access Bank. TIMESLOT: 64Kbyte/s channels on a T1 span. A T1 span contains 24 timeslots. TRANSMISSION ONLY (TO): An operating mode on a 4-wire E&M card that provides dedicated oneway transmission paths to radio and modem equipment uncorrupted by the insertion of A/B robbed bit sig- naling. TRUNK PROCESSING (TP): WINK: A signal sent between two telecommunications devices as part of a handshaking protocol. It is a momentary interruption in SF (Single Frequency) tone, indicating that the distant Central Office (CO) is ready to receive the digits that have just been dialed. In telephone switching systems, a single supervisory pulse. On a digital connection such as a T1 circuit attached to an Access Bank II, a wink is signaled by a brief change in the A and B signaling bits. On an analog line, a wink is signaled by a brief change in polarity (electrical + and -) on the line. WINK OPERATION: A timed off-hook signal normally of 140 milliseconds, which indicates the availability of an incoming register for receipt of digital information from the calling office.
