For voice-over-IP, the gateway enables PSTN voice callers to connect from the ISDN network to IP voice callers. The CISCO UNIFIED VIDEOCONFERENCING 3545 PRI GATEWAY supports two PRI ISDN ports. About the Cisco Unified Videoconferencing 3545 Serial Gateway The Cisco Unified Videoconferencing 3545 Serial Gateway supports multimedia conferencing over IP by translating between H.323 and serial protocols. With the help of a V.35 Adtran Imux, the gateway can also translate between H.323 and H.320 protocols. The gateway offers a serial leg for multimedia conferencing over IP by providing an interface for legacy endpoints with serial interfaces, encryption/decryption devices, satellite networks and leased line services. Installation and Upgrade Guide for Cisco Unified Videoconferencing 3545 PRI Gateway and 3545 Serial Gateway Release 5.5 OL-14912-01 1-1 Chapter 1 Functionality About Gateway Features About Gateway Features Table 1-1 lists the major features of the Cisco Unified Videoconferencing 3545 Gateway. Table 1-1 Gateway Feature Summary Feature Description Interoperability The gateway provides a high degree of interoperability with other H.323 compliant gateways, gatekeepers, terminals, proxy, and Multipoint Control Unit (MCU) products by being based on the H.320 standard and H.323 protocol stack. Web-based management The gateway features the gateway interface. This is a web interface used to configure and monitor the gateway. You can view and modify all aspects of the gateway configuration from a remote location using a Java-enabled web browser. SNMP management The gateway features Simple Network Management Protocol (SNMP) management that supports all aspects of monitoring, diagnostics, configuration, and trapping. Diagnostics The gateway features front and rear panel LED indicators that display status for the unit. You can also access remote diagnostics of the unit through the gateway interface, Telnet, SNMP, or a serial port. Network load balancing The gateway supports load balancing on the network by communicating with a gatekeeper through H.323 RAI (Resource Available Indication)/RAC (Resource Available Confirmation) messages. T.120 data collaboration The gateway supports data transfers in calls between ISDN and IP by using high speed T.120 in HMLP and VarMLP formats. Quality of service (QoS) The gateway features configurable coding of media packets to achieve QoS routing priority on the Internet Protocol (IP) network. The Type of Service (ToS) bits of the IP datagram header can be configured for priority level. Dial plan The gateway supports a simplified dial plan for outbound dialing using a single universal prefix. Using the dial plan, the gateway automatically detects the capabilities received in the Setup message from the IP endpoint and sets the same bit rate for the ISDN (or serial interface) side of the call. Direct dialing and call The gateway dial plan supports the following direct dialing and call routing routing facilities: • Direct Inward Dialing (DID) • Multiple Subscriber Network (MSN) • Q.931 Sub-addressing Information Element Cisco Unified Videoconferencing 3545 Serial Gateway supports DID in DCE mode only. • Internal and External Interactive Voice Response (IVR) • TCS4 • Default extension Installation and Upgrade Guide for Cisco Unified Videoconferencing 3545 PRI Gateway and 3545 Serial Gateway Release 5.5 1-2 OL-14912-01 Chapter 1 Functionality About Gateway Features Table 1-1 Gateway Feature Summary (continued) Feature Description Access control The gateway features password-controlled access to the gateway interface. Up to ten different administrator access profiles can be defined for the gateway. DTMF translation The gateway supports translation between in-band Dual Tone Multi-Frequency (DTMF) signals (on the ISDN side) and out-of-band H.245 messages (on the IP side). DTMF translation occurs for voice and video calls. Dual video The gateway supports H.239 standards-based dual video and TANDBERG DuoVideo technology. Dual video streams enable a screen to carry video images from one source while simultaneously displaying images from a second source. Hot swap The gateway features hot swap functionality that you can use to remove and replace gateway cards under power. Conceal caller ID The gateway supports a conceal caller ID feature that instructs the gatekeeper to conceal the identity of the calling endpoint on the IP or ISDN network, whether the presentation restricted feature is enabled or not. H.323 fast start The gateway H.323 fast start feature enables endpoints to join a voice conference in the gateway more quickly. ISDN rollover (available in Cisco Unified Videoconferencing 3545 PRI Gateway only) The gateway features ISDN rollover. In this feature, the gateway sends a “busy out” channel request to the PSTN switch when the current PRI connection is left with less than a predefined number of available B channels. The PSTN switch “rolls over” to the next available gateway. Network Specific Facility (available in Cisco Unified Videoconferencing 3545 PRI Gateway only) The gateway provides support for Network Specific Facility Information Elements (NSF IEs) which enable system administrators to specify to service providers the equipment, service, or network through which they want a call routed. ISDN connection failure The gateway responds to ISDN connection failure events, by unregistering from its gatekeeper. The gatekeeper is forced to send new IP-to-ISDN calls through a different gateway, thus ensuring high call completion rates. The gateway re-registers to the gatekeeper when the ISDN connection is restored. Downspeeding The gateway features downspeeding functionality. In the downspeeding feature, the gateway attempts to reconnect a disconnected video call either at a lower bandwidth or as a voice call. Downspeeding contributes to a higher percentage of call completion on the network. The gateway supports downspeeding at call setup and in mid-call. Multiple trap server support The gateway supports up to three SNMP trap servers. H.239 support The gateway supports the H.239 protocol in ISDN-to-IP calls and in IP-to-ISDN calls. Installation and Upgrade Guide for Cisco Unified Videoconferencing 3545 PRI Gateway and 3545 Serial Gateway Release 5.5 OL-14912-01 1-3 Chapter 1 Functionality About Gateway Features Table 1-1 Gateway Feature Summary (continued) Feature Description Encryption support The gateway supports H.235-compliant AES 128 encryption for calls over IP networks, and H.233 and H.234-compliant AES 128 encryption for calls over ISDN networks. H.243 Conference Control support The gateway supports the H.243 protocol in ISDN-to-IP calls and in IP-to-ISDN calls. The gateway identifies the protocol version that an IP endpoint uses and sends H.239 capabilities only to those endpoints working with protocol version 4.0 or later. Peer-to-peer connectivity The gateway supports connectivity to the IP network through a gatekeeper, or directly to a peer device such as Cisco Unified Communications Manager. IP network connections The gateway has one 10/100Base-T Ethernet IP port (on the front panel) and connects to an IP segment through a direct connection to a network switch.

Table 1-3 Note PRI Gateway Call Handling Capacity Call Type Maximum Number of Calls Using 1 x E1 PRI Line Maximum Number of Calls Using 1 X T1 PRI Line Maximum Number of Calls Using 2 x E1 PRI Lines Maximum Number of Calls Using 2 x T1 PRI Lines voice (64 Kbps) 30 23 60 46 2B video (128 Kbps) 15 11 30 23 6B video (384 Kbps) 5 3 10 7 12B video (768 Kbps) 2 1 5 3 Enabling ISDN-to-IP DTMF detection in the PRI gateway for video calls reduces the number of supported calls by half. About Gateway Call Bandwidth Overhead According to the H.320 standard, the available bandwidth allocated to a call at any given bit rate will always be slightly less than the stated maximum for the following reasons: • All stated maximum call bandwidths include provision for control, audio, video, and data traffic. • Video traffic on the ISDN side contains additional bits for error correction purposes which also consume bandwidth. Video traffic on the IP side does not include this additional load. • Opening an audio channel further reduces the bandwidth available to the video traffic. For example, a call at 384 Kbps actually has only 363 Kbps available to it. Control and error correction account for the remaining 21 Kbps. Installation and Upgrade Guide for Cisco Unified Videoconferencing 3545 PRI Gateway and 3545 Serial Gateway Release 5.5 OL-14912-01 1-13 Chapter 1 Functionality About Cisco Unified Videoconferencing 3545 Gateway Functionality Resource Allocation across E1/T1 Lines The gateway can allocate bandwidth resources to calls across separate E1 or T1 connections to maximize bandwidth capacity in cases where there is not enough capacity for a call on a single E1 or T1 connection, but where sufficient capacity does exist when remaining capacity on both E1/T1 lines is combined. For example, a gateway using two T1 lines can support three 6B calls on each T1 line, with 320 Kbps spare capacity per line: • Each T1 line provides 23 B channels. • Each B channel supports 64 Kbps • Each T1 line supports 23 x 64 = 1472 Kbps • Each 6B call requires 6 x 64 = 384 Kbps • Each T1 line supports 1472/384 = 3 6B calls + 320 Kbps spare The gateway processes an additional 6B call requiring a further 384 Kbps by taking bandwidth resources from each of the two T1 lines, both of which have 320 Kbps available. In this way, the gateway spreads the call over both T1 lines. About Peer-to-Peer Connectivity The gateway supports the following types of connectivity to the IP network • Through a gatekeeper • Directly to a peer device such as Cisco Unified Communications Manager without the need for a gatekeeper.

Step 6 Secure the blank cover panel screws. Caution Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Initial Gateway Configuration Initial monitoring and administration of the gateway are performed from a remote PC via a serial connection. This allows you to access the boot configuration menu of the gateway. At power-up, the gateway goes through the following boot phases: Note • Auto-boot—The embedded operating system initializes and displays basic information. • Configuration menu—A 6-second countdown allows you to enter the configuration menu. • Initialization—The gateway completes its boot sequence and is ready for operation. You can perform serial port configuration of the gateway only at startup, during a short period indicated by a 6-second countdown. Once the initialization phase is complete, the only way you can access the configuration menu is by restarting the gateway. Connecting to a PC This section describes how to use the serial port connection to configure the gateway with an IP address. Procedure Step 1 Locate the terminal cable shipped with the gateway. Step 2 Connect the end labeled PC to the serial port on the computer. Step 3 Connect the end labeled Unit to the serial port connector on the gateway front panel. Note The PC terminal should have an installed terminal emulation application, such as HyperTerminal.
