Model Number Codes (LEDR 1400S) 2.0 INSTALLATION Installation of the LEDR transceiver is not difficult, but it does require some planning to ensure optimal efficiency and reliability. This section provides tips for selecting an appropriate site, choosing antennas and feedlines, and minimizing the chance of interference. This material should be reviewed before beginning equipment installation. 2.1 General Requirements There are four main requirements for installing the transceiver—a suit-able installation environment, adequate and stable primary power, a good antenna system, and the correct interface between the transceiver and the external data equipment. Figure 6 shows a typical station arrangement. Invisible place holder Figure 6.

MDS 05-3627A01, Rev. A LEDR “S” Series I/O Guide 5 Site Selection For a successful installation, careful thought must be given to selecting proper sites for the radios and antenna systems. Suitable sites should offer:• An antenna location that provides an unobstructed path in the direction of the associated station• A source of adequate and stable primary power• Suitable entrances for antenna, interface or other required cabling• Adequate clearance around the radio for ventilationThese requirements can be quickly determined in most cases. A possible exception is the first item—verifying that an unobstructed transmission path exists. Microwave radio signals travel primarily by line-of-sight, and obstructions between the sending and receiving stations will affect system performance. This is especially important for the LEDR 1400S, which operates in the 1400 MHz microwave frequency band.If you are not familiar with the effects of terrain and other obstructions on radio transmission, the following discussion will provide helpful background. Terrain and Signal Strength A line-of-sight path between stations is highly desirable, and provides the most reliable communications link in all cases. A line-of-sight path can often be achieved by mounting each station antenna on a tower or other elevated structure that raises it to a level sufficient to clear sur-rounding terrain and other obstructions.The requirement for a clear transmission path depends upon the distance to be covered by the system. If the system is to cover only a limited dis-tance, say 5 km (3.1 miles), then some obstructions in the transmission path may be tolerable. For longer-range systems, any obstruction could compromise the performance of the system, or block transmission entirely.The signal strength at the receiver must exceed the receiver sensitivity by an amount known as the fade margin to provide reliable operation under various conditions.Detailed information on path planning should be reviewed before begin-ning an installation. See RF Propagation Planning on page 87 for more information. Computer software is also available for this purpose that can greatly simplify the steps involved in planning a path.

6 LEDR “S” Series I/O Guide MDS 05-3627A01, Rev. A Adaptive Broadband/MDS offers path analysis (for paths in the USA) as an engineering service. Contact the factory for additional informa-tion. On-the-Air Test If you’ve analyzed the proposed transmission path and feel that it is acceptable, an on-the-air test of the equipment and path should be con-ducted. This not only verifies the path study results, but allows you to see firsthand the factors involved at each installation site.The test can be performed by installing a radio at each end of the pro-posed link and checking the Received Signal Strength Indication (RSSI) value reported at the front panel LCD screen of each radio. If adequate signal strength cannot be obtained, it may be necessary to mount the sta-tion antennas higher, use higher gain antennas, or select a different site for one or both stations. A Word About Interference Interference is possible in any radio system. However, since the LEDR radio is designed for use in a licensed system, interference is less likely because frequency allocations are normally coordinated with consider-ation given to geographic location and existing operating frequencies.The risk of interference can be further reduced through prudent system design and configuration. Allow adequate separation between frequen-cies and radio systems. C/I Curves A carrier to interference (C/I) curve can help in frequency and space coordination. The information in this curve can aid greatly in helping plan geographic locations and frequency usage for radio systems. Con-tact the factory for additional information on carrier to interference curves. A whitepaper on the subject is available on request. Ask for Pub-lication No. 05-3638A01.Keep the following points in mind when setting up your point-to-point system:1. Systems installed in lightly populated areas are least likely to encounter interference; those in urban and suburban environments are more likely to be affected by other devices operating in the radio’s frequency band and adjacent services.2. Directional antennas must be used at each end of a point-to-point link. They conﬁne the transmission and reception pattern to a com-paratively narrow beam, which minimizes interference to and from stations located outside the pattern. The larger the antenna, the more focused the transmission and reception pattern and the higher the gain.

MDS 05-3627A01, Rev. A LEDR “S” Series I/O Guide 7 3. If interference is suspected from another system, it may be helpful to use antenna polarization that is opposite to the interfering sys-tem’s antennas. An additional 20 dB (or more) of attenuation to interference can be achieved by using opposite antenna polarization. Refer to the antenna manufacturer’s instructions for details on changing polarization. 2.2 Antenna and Feedline Selection Antennas The antenna system is perhaps the most crucial part of the system design. An antenna system that uses poor quality feedline, or is improp-erly aligned with the companion site, will result in poor performance, or no communication at all.A directional antenna must be used for point-to-point systems to mini-mize interference both to and from nearby systems. In general, cylin-drical or dish type antennas with a parabolic reflector must be used. Yagi or corner reflector types may be acceptable in some applications. Check government regulations.The exact style of antenna used depends on the size and layout of a system. In most cases, a directional “dish” type of antenna is used with the radio (Figure 7). Dish antennas maximize transmission efficiency and restrict the radiation pattern to the desired transmission path. Invisible place holder Figure 7. Typical Grid Dish Antenna

8 LEDR “S” Series I/O Guide MDS 05-3627A01, Rev. A Table 1, Table 2 and Table 3 list some common grid dish antenna sizes and their approximate gains.Adaptive Broadband Corporation/MDS can also furnish antennas for use with the transceiver. Consult your sales representative for details. Feedlines For maximum performance, a good quality feedline must be used to connect the transceiver to the antenna. For short-range transmission, or where very short lengths of cable are used (up to 8 meters/26 feet), an inexpensive coax cable such as Type RG-213 may be acceptable. Table 1.

MDS 05-3627A01, Rev. A LEDR “S” Series I/O Guide 9 For longer cable runs, or for longer-range communication paths, we rec-ommend using a low-loss cable suited for 1400 MHz, such as Andrew Heliax ® . Whichever type of cable is used, it should be kept as short as possible to minimize signal loss.Table 4, Table 5 and Table 6 list several types of acceptable feedlines and the associated losses according to operating frequency.Table 6 lists several types of acceptable feedlines and the associated losses at 1400 MHz. 2.3 Radio Mounting The radio can be mounted either in a 19-inch equipment rack or on a table top. It should be located in a relatively clean, dust-free environ-ment that allows easy access to the rear panel connectors as well as front panel controls and indicators. Air must be allowed to pass freely over the ventilation holes and heat sink on the side panel. Table 4.

The top connector is for Radio A, and the bottom con-nector is for Radio B. For pinout information, see Figure 26 on page 86.EIA-530-AThis DB-25 connector provides a connection point for customer-sup-plied EIA-530 data equipment.Service ChannelIn a protected configuration, this DB-9 connector becomes the Service Channel connection for both LEDR radios. (The Service Channel con-nectors on the radios become non-functional.) For detailed pin informa-tion, see “Service Channel” on page 86.2.6 Inter-Unit Cabling for Protected StationsThe required cabling between the two radios and the Protected Switch chassis is shown in Figure 11.

MDS 05-3627A01, Rev. A LEDR “S” Series I/O Guide 15Invisible place holderFigure 11. Inter-unit Cabling—Protected Version3.0 OPERATIONThe LEDR radio is designed for continuous, unattended operation. Under normal conditions, the only time operator intervention is required is to power the unit up or down, or to change an operating parameter. This section explains the use of the radio’s controls and indicators and provides steps for initial startup of the equipment.3.1 Initial StartupNOTE: The LEDR radio is normally keyed continuously, and the radiowill transmit whenever power is applied. Ensure there is a suit-able load on the antenna connector before connecting power.Operation of the radio can be started by simply connecting primary power to the unit. After a short self-test, a “default screen” similar to the following appears on the radio’s LCD display:TxBAntenna TxARxBRxA 530 (A&B) EIA-530-A Service ChannelEthernetE1ProtectedTXExternal Data InterfaceEIA-530-AEthernetNMSServiceChannel Alarm I/O DC Power InputEIA-530-AEthernetNMSData InterfaceServiceChannel Alarm I/O DC Power InputTOSTATIONANTENNA1234NOT USED WITHFT1-EQUIPPED RADIOSTO ETHERNET HUBTO EIA-530DATA EQUIPMENTSERVICE CHANNEL(SERVES BOTH RADIOS)RXCOAXIAL CABLES (4)P/N 19-1323A02 RIBBON CABLEP/N 03-3828A01SCSI CABLEP/N 03-3837A01TXExternalRXG.703/Expansion DataG.703/Expansion DataNOT USED INPROTECTED CONFIG.NOT USED INPROTECTED CONFIG.RADIO ARADIO BPROTECTED SWITCHRIBBON CABLEP/N 03-3828A01SCSI CABLEP/N 03-3837A01 LLLLEEEEDDDDRRRR LLLLiiiinnnnkkkk RRRRSSSSSSSSIIII:::: ----66660000 ddddBBBBmmmm

AMaximizing RSSIFor newly installed systems, one of the first tasks is to orient the station antenna for a maximum Received Signal Strength Indication (RSSI) as shown on the LCD screen. See “Performance” on page 30 for details. A maximum RSSI ensures the antenna is properly aimed at the associated station. Move the antenna slowly while an assistant observes the RSSI display for a maximum reading.Initial Login—Required to change radio settingsWhen the radio is first powered up, it defaults to a read-only condition. That is, the radio parameters may be viewed, but cannot be changed. To enable changes to radio settings, a valid user name and password must be entered.When the radio is shipped from the factory, it is pre-programmed with the following temporary login credentials:Username: SUPER Password: SUPERKeypad Method To log in from the front panel using the temporary credentials, follow these steps:1. Go to the Login screen and press the front panel key. The Username screen appears with SUPER displayed.2. Press the key again to access the Password screen. Use the arrow keys to scroll through the list of characters and individually select the letters spelling out the word SUPER. Press after each character selection. (For more information on character selection using the keypad, see “Communicating with the Radio” on page 18.)3. When all of the characters have been entered, press again. The screen brieﬂy displays Login Success and returns to the Login entry screen.The user may now access any of the screens shown in Figure 14 with Administrator level privileges (the highest allowable user level).Console Method To login using a terminal connected to the front panel console port, follow the steps below. (For more information on connecting a terminal, see “Console Port” on page 35.)1. Connect a terminal to the radio’s front panel console port and press . The ADAP> prompt will appear.2. Enter login SUPER. The Password > prompt will appear.ENTERENTERENTERENTERENTER

MDS 05-3627A01, Rev. A LEDR “S” Series I/O Guide 173. Enter the password SUPER. The following response appears: login: SUPER logged in. The user may now access any of the console commands listed in Table 12 on page 36 with Administrator level privileges (the highest allowable user level).Changing the SUPER Password (Recommended)The factory-programmed username and password (SUPER) is provided to enable a System Administrator to operate a newly installed radio. It is highly recommended that the password for SUPER be changed as soon as possible to maintain system security.Follow these steps to change the factory-programmed password:1. Login as SUPER using the Console Method described above. (Passwords cannot be changed using the front panel keypad.)2. Enter the command passwd. At the next prompt, enter a new pass-word (eight characters maximum).3. Re-enter your new password (for veriﬁcation purposes). If the entry is correct, the radio responds with user: Command Complete.You may now set up additional accounts, set permission levels, or delete accounts as desired using the user command. See page 58 for complete description of this command.NOTE: It is recommended that users log out when finished using thekeypad or console terminal. This can be done using the Logoutscreen on the radio, or the logout command from a consoleterminal as appropriate. If there is no keypad or terminalactivity for 10 minutes, the radio automatically logs out andreverts to read-only status.

18 LEDR “S” Series I/O Guide MDS 05-3627A01, Rev. A3.2 Communicating with the RadioThere are four different methods available to set radio parameters and query the radio.•Front Panel—The front panel is intended to serve as a conve-nient user interface for local radio management. Most, but not all, parameters and functions are accessible from the front panel.•SNMP Network Management System—The SNMP agent interface is optimized to fulfill the fault configuration, perfor-mance and user access requirements of the LEDR radio system. A separate guide, P/N 05-3532A01 explains SNMP in more detail.• Telnet—A standard network application protocol which pro-vides a console-type interface to configure and query most radio parameters.• EMS (Element Management System)—The EMS is used via a terminal connected to the front panel console port. It may be used to configure and query every manageable radio parameter on a given network using the out-of-band service channel. The EMS may be used on the local radio (login command) or on the remote radio (rlogin command).Front Panel ControlsFigure 12 shows the LEDR radio’s front panel controls and indicators. The front panel includes LEDs, an LCD display screen and a menu nav-igation keypad. Figure 12. Front Panel InterfaceMENU NAVIGATION BUTTONSALARM STATUS LEDSSTATUS LEDS LCD DISPLAY

MDS 05-3627A01, Rev. A LEDR “S” Series I/O Guide 19LEDs The front panel LEDs indicate the following conditions when lit:POWER—Main Power is applied to radio.ACTIVE—This is the Primary unit in a redundant configuration.ALARM—A general alarm condition is presentRX ALARM—The modem is not locked to a receive signalTX ALARM—There is a problem with the transmitterI/O ALARM—There is a payload data interface errorLCD Display/Keypad The LCD display provides a 2 line by 16 character readout of radio status and parameter settings. It is used with the menu navigation keypad on the right side of the front panel to control the radio’s opera-tion and access diagnostic information.Use of the keypad (Figure 13) is simple, and allows many basic oper-ating tasks to be performed without connecting an external terminal or using additional software.Invisible place holderFigure 13. Menu Navigation KeypadThe keypad buttons can be used for two functions; Navigation, and Editing. The functions of the keys are automatically selected according to the screen that is being viewed by the user. •Navigation Mode—This is the default mode. The left and right keys ( ) navigate through the available top level screens (see menu tree, Figure 14). The key allows entry into a screen, exposing another level of menus or entering edit mode for a radio parameter. The key always exits the current screen, causing the program to “pop out” one level.•Edit Mode—In editable screens, pressing the key puts the screen in Edit mode. The technique for applying new data depends on the particular edit mode used by that screen. LEDR screens have four edit sub-modes; List, Character edit, Text Entry, and Horizon-tal Bar.ENTERENTERENTER

20 LEDR “S” Series I/O Guide MDS 05-3627A01, Rev. AIn List mode, the left and right keys scroll through a list of choices. Pressing when the desired choice is selected attempts to apply the changes. Pressing drops out of the edit mode without saving changes.The Character Edit mode consists a cursor move mode and a character scroll mode. Upon entering the Character Edit mode, the left and right keys move the cursor in the corresponding direction. When the cursor is below the character to change, pressing again puts the screen in character scroll mode in which the left and right keys scroll through the available charac-ters. Pressing saves the new character and reverts to cursor move mode. To save all changes made in cursor move mode, place the cursor under the special “Enter” character and press . Pressing in character scroll mode reverts to cursor move mode. Pressing in cursor move mode cancels char-acter edit mode without saving any changes.The Text Entry mode is a slight modification to the Character Edit mode above. Upon entering Text Entry mode the cursor is in the leftmost position and the keys scroll through the available characters. Pressing saves the current character and moves the cursor to the next position to the right. When the text is correctly entered, moving the cursor to the special “Enter” character and pressing attempts to save the new text. Pressing in cursor move mode cancels Text Entry mode without saving any changes.The Horizontal Bar mode is used in some menu screens. It allows adjustment of the LCD display for the best contrast using the keys (see Front Panel menu, page 33). The right key corresponds to upward viewing angle; the left key corresponds to downward viewing angle. Pressing saves the adjusted value as the default setting.It works in a similar manner for the Orderwire menu (see page 33) to adjust the Volume and VOX threshold.Front Panel Menu TreeThe LEDR radio contains several top level menus (see Table 8). These serve as entry points to a variety of sub menus that can be used to view or adjust operating parameters and diagnose the radio link.ENTERENTERENTERENTERENTERENTERENTERENTERENTERENTERENTERTable 8.

If desired, the default screen may be changed (see “ Default Screen ” on page 34). Login The login menus allow you to log in to the radio’s operating system and gain access to configuration and diagnostics functions permitted for your assigned access level.The username menu is where you specify the user name assigned by the user access administrator.The password screen is where you specify the password associated with your user name to gain access to the login account. A maximum of eight characters are allowed. Network This menu allows changes to the radio’s IP address. The IP address is used for SNMP connectivity. The IP address also allows new radio soft-ware to be downloaded over-the-air. This menu allows the subnet mask to be viewed and changed. The subnet mask specifies which bits of the host IP address can be re-used for increased network addressing efficiency.Example: Consider an IP address in a Class C network, such as 150.215.017.009. The Class C network means that the right-most group of numbers (009) identifies a particular host on this network. The other three groups of numbers (150.215.017) represent the network address.

A subnet mask of 255.255.255.127 allows half of the host portion of the IP address to be reused to define sub-networks.This menu allows the Gateway IP address to be viewed or set. The Gateway IP address is the address of the radio that connects the radio network to an IP network.This menu allows selection of the Default IP port for networking con-nections to the LEDR radio. The Ethernet selection is used for cable con-nection to a Local Area Network (LAN) or repeater via the radio’s rear panel ETHERNET NMS connector.The AIR selection is commonly used for over-the air (RF) networking between radios, but may also be used with a back-to-back cable connec-tion between two radios via the radio’s rear panel ETHERNET NMS con-nector. This type of communication uses the SNAP protocol and requires the use of an ethernet crossover cable. General This menu allows the Unit ID of the radio to be displayed or changed.

MDS 05-3627A01, Rev. A LEDR “S” Series I/O Guide 39Command DescriptionsThe following commands are available through the console port. The conventions used for these commands are similar to UNIX com-mand-line structure. These commands all require the Enter or Return key be pressed after the command. The following conventions are used to help describe the usage of the commands. Square brackets [ ] contain subcommands that may or may not be needed as part of the desired command. If there is more than one possible subcommand a vertical line | separates the commands within the square brackets. A subcommand is an optional exten-sion of the command and changes the basic command. Angle brackets <> contain arguments. The arguments are values needed to carry out the command such as a frequency value or option. ? or help Usage: helpThis command returns a list of currently available commands. In addi-tion, entering help as a subcommand before or after a command returns usage information regarding the command. A ? (question mark) can be also be used to invoke help.

If boot is entered alone, the currently active image is displayed. A selection of 1 or 2 after the command (e.g., boot 2) indicates which software image to boot. (A message appears to confirm that you wish to reboot the software.) Upon reboot, the radio software and all radio func-tions are restarted in a manner similar to turning the radio power off and then on again. The radio is taken out of service until it reinitializes.A choice of software images allows booting an alternate version of radio software. The ability to have two radio resident software images allows radio software reprogramming over-the-air and the ability to restore operation to the original software if required.buzzer Usage: buzzerThis command briefly sounds the radio’s piezo buzzer for testing.Example response:buzzer: Starting testbuzzer: Test completecoffset Usage: coffsetThis command displays the Modem Carrier Frequency Offset.con Usage: con (baud [300|1200|2400|4800|9600|19200|38400|115200]) (parity [none|even|odd])This command sets or displays the console serial port operating param-eters.

Aclkmode Usage 1 (EIA-530 operation): clkmode [<internal|exttx|looped|extdce>] Usage 2 (E1/T1 operation): clkmode [<internal|remote|1-4|linename>] This command is used to set or display the master clock source for the radio system. Several different clocking schemes can be used. See “Transmit Clock Selection” on page 62 for clocking arrangements.NOTE: Earlier versions of the software may display the Clock Modeas NORMAL instead of INTERNAL.Usage 1 Subcommands:internal—Internal oscillator source (default).exttx—Clock from external equipment.looped—Recovered RF (RX) clock.extdce—Some other source.Usage 2 Subcommands:internal—Internal oscillator source (default).remote—Over-the-air, RX data derived.1-4—Recovered RF (RX) clock.linename—Loop timing from specified line interface.In E1/T1 operation only, the clkmode command allows the various pos-sible clock sources to be prioritized for fallback. As timing sources become available, the highest-priority source will be chosen by the system. If attaching to the network or equipment that provides timing, a universal form of the command would be clkmode 1234 internal. If attaching to equipment that will provide looped-back timing, a uni-versal form of the command would be clkmode remote internal. If both ends of the link provide looped-back timing, the internal clock source should be selected by entering clkmode internal. Note that at least one end of the link should have either network or internal timing selected.date Usage: date [MM/DD/YYYY]Subcommands: date format [<1-3>] (1-US, 2-European, 3-generic)This command sets or displays the date and time of the radio’s internal real-time clock. The real time clock operates from an internal lithium battery so it is running even if the radio has no DC power connected. The date format may also be set or displayed from this screen for one of three formats: U.S., European, or generic.The real time clock is fully compliant with year 2000 standards.Example response: date: 07-JUN-1999 08:11:30date format: dd-MON-yyyy (3)

MDS 05-3627A01, Rev. A LEDR “S” Series I/O Guide 49login Usage: loginThis command allows access to configuration and diagnostics informa-tion as allowed by the radio system administrator. Example:ADAP> login .Returns:Username>Type: john (or appropriate user name) Returns:Password>Type: (password) NOTE: Passwords must not exceed eight characters.See user command on page 58 for more information on user access levels.logout Usage: logoutThis command is used to log out as a user of the radio configuration and diagnostics functions. loopback Usage 1: loopback none|rf|local|remote|iol [linelist]|ior [linelist] <timeout>]Usage 2: loopback [inb|outb] [linelist] [on|off] [-u <code>] [-d <code>]The loopback command is used to set or display the loopback mode that can be used for diagnostic purposes. Entering loopback without any parameters displays the current loopback mode.Usage 1 subcommands:The none subcommand disables all loopback operation. This is the mode for normal point-to-point operation. The rf subcommand enables an RF loopback mode. This mode allows testing of the local transceiver’s transmit and receive chain. RF loopback testing is a valuable diagnostic tool, but it should not be considered an exhaustive test of the transceiver. In some cases, interac-tion between the transmit and receive phase-locked loops (PLLs) can occur, causing erroneous results during testing. Changing the trans-ceiver’s RF output setting may resolve these problems.ENTERENTERENTER

50 LEDR “S” Series I/O Guide MDS 05-3627A01, Rev. AIn addition, on all LEDR radios except the LEDR 1400 Series, the transmit and receive frequencies must be within the same band for RF loopback to function.The local subcommand enables a local digital loopback mode. With this test, incoming bits are sent back out the radio’s DATA connector before the modem module. This can be used to verify proper interconnection between the radio and the connected equipment. None of the radio’s RF circuitry is involved in this test. (This description is true for EIA-530 operation only.) For T1/E1 operation, the local subcommand enables a local digital MUX loopback in the transceiver’s T1/E1 option card before going out to the main board.The remote subcommand instructs the radio at the other end of the link to “echo” all of the data it receives. This is an effective way of testing the entire communications system, including the transmission path over the air. (In the event of a communications failure with the remote radio, the message “Remote Error” is displayed, and no loopback mode is selected. (This description is true for EIA-530 operation only.)For T1/E1 operation, the remote subcommand mimics the ior subcom-mand described below.The iol subcommand refers to the local line loopback.The linelist variable represents a list of local line interfaces. It can consist of a single line number or linename, a comma separated list of line num-bers or linenames, a range of line numbers (i.e., 1–4), or if linelist is not given all lines. See Table 13 on page 44 for a list of line numbers.The ior subcommand refers to the remote line loopback. Remote loop-back port selection is relative to the local port. The radio link will trans-late any line mapping to select the correct physical remote port to loop back, based on the selected local port.The timeout variable may be set between 0 minutes (never time out) and 60 minutes.Usage 2 subcommands:The inb subcommand refers to the inband loopback configuration.The outb subcommand refers to the outband ESF (Extended Super Frame) loopback configuration.The linelist subcommand is identical to that described for Usage 1.The on|off subcommands allow turning the loopback feature on or off.

MDS 05-3627A01, Rev. A LEDR “S” Series I/O Guide 51The -u <code> subcommand allows setting of the inband|outband loop-back upcode.The -d <code> subcommand allows setting of the inband|outband loop-back downcode.The inband code consists of 1-7 bits, binary format.Example: 00001 The outband code consists of 6 bits within the 16 bit ESF data link code-word.Example: 000111within 16 bit codeword: 0<000111>0 11111111menu This command starts the LEDR radio’s menu wizard.model Usage: modelThis command displays the radio model number. This information is programmed at the factory and cannot be changed. modem Usage: modem [matrix id] [bandwidth] [+fdl] [+cas]This command sets or displays the radio modem and data rate. Table 15 shows the available number-letter combinations that can be entered for a radio with a 200 kHz bandwidth. Note that the E1/T1 selections are only valid on radios equipped with an FT1 Option Board.Command Example: To set 16-QAM/384 kbps, enter modem B4 200network Usage: networkThis command displays the radios that can be reached via the service channel for Orderwire and Element Management System (EMS) diag-nostics.Table 15.

It can be enabled or disabled using the hitless on|off command.The ip subcommand is used to set or display the associated (sibling) radio’s IP address.

MDS 05-3627A01, Rev. A LEDR “S” Series I/O Guide 53NOTE: The associated radio IP address should be programmed to theIP address of the other radio connected to the protectedswitching chassis. The associated radio IP address is used bythe redundant radio to share information between the units.This address is necessary for warm-standby switching but notfor hot-standby. However, the redundant radio will performbetter if their associated radio IP address is programmedcorrectly. The associated radio IP address does not affect IProuting and forwarding, SNMP, or Telnet.The status subcommand shows the state of both radios. Two status lines are displayed; This Radio and Other Radio.The swxcvr subcommand forces a switchover to the non-active trans-ceiver. (The newly selected unit becomes the active transceiver.)The temp command is used to set or display the over-temperature limit (where switchover to the other radio occurs).The mode command is used to set or display one of three redundant oper-ation modes (0= Standalone, 1= 1+1 Hot Standby, 2= 1+1 Warm Standby).Example Response for rdnt command:rdnt {status}: This Radio = OKrdnt {status}: Other Radio = OKrdnt {active}: inactiverdnt {mode}: 1+1 Hot Standbyrdnt {ip}: 10.2.142.143rdnt {hitless}:onrdnt {default}: yesrdnt {temp}: 80reframe Usage: reframe [linelist] [2of4 | 2of5 | 2of6 | CFAS | CRC]This command is used to set or display the reframe criteria.

Using industry-standard SNMP managers allows seamless integration of the LEDR network or existing systems.Detailed information for using SNMP is provided in the SNMP Hand-book (P/N 05-3532A01) available from Adaptive Broadband/MDS.3.6 Using the OrderwireA handset may be plugged into the front panel of the LEDR radio to allow voice communications between radio sites (see Figure 15). This can be especially useful during setup and service of the radio equipment. The Orderwire function operates similar to a party line. All radios on the network can hear what is said by any individual speaking into a handset. The alert function however, can be directed toward a specific radio.Normal payload data is not affected by Orderwire use. The Orderwire uses voice-compression technology that introduces a slight, but notice-able, delay in Orderwire audio.The Orderwire supports the use of DTMF-type (tone) signaling. An optional handset (P/N 12-1307A01) is required to use the Orderwire.1. Plug the handset into the front panel jack labeled . (Figure 22 on page 84 provides pinout details for this connector.)2. Press or until Orderwire appears on the LCD display.3. To call a speciﬁc radio station, enter the Unit ID number for the sta-tion to be called. (At this point, an alert signal will be sent to a spe-ciﬁc station to “ring” the desired unit.)4. Press the PTT on handset and speak to the other station(s). Release the handset PTT to listen. VOX (voice-activated transmit) operation is also supported.5. Alternatively, a DTMF-style handset can be used to “dial” the required radio station.

Orderwire Connection3.7 Bandwidths, Data Rates and Modulation TypesThe available bandwidth is permanently configured at the factory and cannot be changed by the user. However, the modulation type and data rate can be changed provided the bandwidth is sufficient to support the modulation type and data rate. Table 17 shows the combinations of radio bandwidth, data rates and modulation types that are available at the time of publication.Use of the modem command (page 51) automatically determines if the combination of data rate, bandwidth and modulation type is allowable.Table 17.

62 LEDR “S” Series I/O Guide MDS 05-3627A01, Rev. A3.8 Transmit Clock SelectionThe transmit clock selection must be addressed for every radio in every installation. The single most important consideration is that there be only one master clock in the radio network. The master clock can origi-nate from the radio or from the Customer Premise Equipment (CPE). The radio is capable of several different clocking modes. Refer to Figure 16, Figure 17 and Figure 18 for typical system clocking methods. Refer to the Clock Mode screen description on page 27 for setting the radio transmit clocking from the front panel. Refer to the clkmode description on page 42 for setting the radio transmit clocking mode from the console port.NOTE: When customer premises equipment (CPE) is operated inlooped clock mode, it is recommended that the radio not be setto line clock mode. To do so may cause the transmitting radio’sPLL to be pulled out-of-lock, especially when operating at 4E1data rates.Invisible place holderFigure 16.

64 LEDR “S” Series I/O Guide MDS 05-3627A01, Rev. A3.9 Protected (1+1) LEDR RadioThe LEDR radio may also be supplied in a Protected (redundant) con-figuration (Figure 19). The protected version is designed to perform automatic switchover to a second radio in the event of a failure in the primary unit.Protected operation is important for many mission critical or revenue producing links. By configuring two identical LEDR radios in parallel and including a third switch box containing the RF switching circuits and the customer interfaces, it is possible to protect against failure in any of the LEDR radio sub-systems, either through malfunction or external environmental effects such as multipath fading or nearby lightning strikes.A Protected station consists of two standard LEDR radios and a Pro-tected Switch Chassis (center unit in Figure 19). Ordinarily, the three chassis are mounted together in a “stacked” arrangement as shown.Invisible place holderFigure 19. LEDR Radio Protected VersionProtected OperationDuring normal operation, one radio path is selected and the RF and interface switches are set to service that path. (An LED indicator on the front panel of the Protected Switch Chassis shows the active unit.) A switch on the transmitter circuitry allows one transmitter to be con-nected to the antenna port. On the receive path, a coupler allows both radio receivers to detect the receive signal.

MDS 05-3627A01, Rev. A LEDR “S” Series I/O Guide 65Transmitter Failure Any failure on the "active" transmitter path will raise a fault condition causing the transmit switch to change and the "standby" transmitter to become the "active" unit. Fault conditions can be programmed from the Network Management System (NMS) software, and can be parameters such as:• Low transmitter power• High transmitter temperature• Synthesizers out of lock• Problem with the option board or framers• CPU failure wherein the CPU watchdog causes a reset• Fan faultThe newly "active" transmit path will remain in use until a manual changeover returns the configuration to the original transmitter path. This allows the link to remain fully operational until the user has replaced the faulty transmitter circuitry.Receiver Failure Both receivers are fed via an RF splitter from the antenna port. Both receive paths are buffered and monitored for receive signal integrity via uncorrectable bit errors. If the "active" receive circuitry fails, uncorrect-able bit errors will be detected. The modem receive switch will first determine that the "standby" receive path is operational (no uncorrect-able bit errors) and will switch accordingly.The protected LEDR radio is available with a number of configuration options, each designed to optimize particular system solutions:•1+1 operation - warm or hot standby: In a warm standby link, the standby transmitter is powered down. In a hot standby link, the standby transmitter is powered up and transmitted in a dummy load. The warm standby option offers the advantages of significantly reduced power consumption, since only one trans-mitter path is powered. However, upon transmitter failure, the switchover takes longer due to the transmitter having to be pow-ered. Thus the hot standby offers the advantages of faster switchover time and increased overall system availability.•1+0 operation: In some applications the user wants the flexibil-ity to offer protected (1+1) operation in the future, but operates a critical link that cannot be decommissioned for the upgrade. The 1+0 configuration provides a single LEDR radio wired through the switch box. This configuration can be upgraded to a full 1+1 protected radio by adding the second radio, without taking the 1+0 radio out of commission and losing critical data.•Symmetrical or asymmetrical receiver splitters: The default protected radio is configured with a 3 dB splitter on the receive path, meaning that each radio’s receiver signal level is equal, but typically 4dB worse than an unprotected radio (3dB due to

66 LEDR “S” Series I/O Guide MDS 05-3627A01, Rev. Asplitter, plus 1dB cabling and additional connectors). As an option, an asymmetrical splitter (1dB / 10dB) is offered. Using this option, the active path is 2 dB stronger than with a symmet-rical splitter (1dB compared to 3dB splitter loss), allowing for a better fade margin and increased system availability during nor-mal operation. However, upon receiver change over, the receive signal strength will be significantly reduced due to the 10dB of splitter loss rather than the equal splitter’s 3dB loss, making the link more prone to fades in this temporary changed over state. Providing the failed standby receiver is replaced within a short period of time, many users find that the asymmetric splitter’s increased normal performance offsets any derating in the temporary switched state.Space Diversity OperationSpace diversity operation is an effective mechanism of increasing a radio link’s resilience to transmission impairments such as multipath fading or frequency selective fading. In difficult transmission environ-ments such as over highly reflective and moving water paths, or in arid environments where atmospheric ducting occurs, space diversity is the most effective way of maintaining a continuous radio link. In a space diversity link, two radio receivers are operated in parallel, from two separate antennas mounted several wavelengths apart verti-cally on the antenna tower. The separation of antennas is such that when one antenna experiences fading due to multi-path interference, the other antenna, being several wavelengths away, will not experience the same fade. Thus, one receive path may experience uncorrectable errors, while the other path will be error free. Similar to the protected operation, the receive modem switch will determine which buffered data path is oper-ating with the highest integrity, and select that path without inducing any additional bit errors into the link.Space diversity is especially effective in changeable multi-path environ-ments such as over tidal water paths. Since water is highly reflective, there will be continual "constructive" and "destructive" interference at each single antenna over the course of the day as the water rises and falls and the reflected water path interferes with the line-of-sight path. By correct vertical positioning of the antennas, these effects can be negated, allowing one antenna to see a good signal while the other is experi-encing fading, and the modem switching accordingly to allow the link to operate error- free.The space diversity LEDR radio is available only in a hot standby con-figuration, with a symmetrical 3dB coupler on the receive paths.

$MDS 05-3627A01, Rev. A LEDR “S” Series I/O Guide 67User Interface & ControlProtected operation is configured using the Redundant screen (page 34) on either radio front panel, or with the rdnt command from a console ter-minal (see page 52).3.10 Fractional T1 Interface Card (Optional Equipment)The fractional T1 interface (FT1) option (P/N 03-3846A01) provides additional connectivity within a LEDR network. The installation of an FT1 option board inside the radio allows the standard EIA-530 customer data interface to be bypassed and connection directly to a G.703 T1 interface.With the FT1 option, users are able to place a LEDR link from a network service access point to a remote site, where an installation supports mul-tiple communications devices. Direct interface to customer equipment such as channel banks is possible without the use of expensive protocol converters.See “Field Installation of FT1 Option Board Non-protected: 03-3846A01 Protected: 03-3539A01” on page 78 for instructions on adding this option to a LEDR radio.Fractional T1 PerformanceThe FT1 option allows the LEDR radio to be connected directly with a G.703 T1 interface. The line rate of the interface operates at the T1 rate of 1.544 Mbps. Twelve user selectable DS-0 timeslots are transmitted over the air in the maximum FCC / IC allowed 200 kHz occupied band-width in the 960 MHz FCC / IC frequency band. The T1 interface is G.703 at 100 Ω line impedance. Physical connection is via an RJ48C jack on the rear panel.Configurable Parameters The following performance specifications of the T1 fractional interface are adjustable by the user. All of these parameters are manageable locally, or over the air via SNMP network management. (Refer to the SNMP Handbook, P/N 05-3532A01 for more information.)Timeslots and Framing—Twelve DS-0 timeslots are permitted, with selection arbitrary. The selection of timeslots may be different at each end of the link, provided their number is equal. The timeslots may not be reordered.Alarm signals RAI and AIS are generated as appropriate. The user may optionally have these signals forwarded over the RF link.The frame format is selectable among: FT only, ESF without CRC checking and generation, SF (D4), SF with JYEL indication, ESF with CRC checking and generation.$

68 LEDR “S” Series I/O Guide MDS 05-3627A01, Rev. AThe re-framing criteria may be adjusted to the following settings: 2 out of 4 Fbit errors, 2 out of 5 Fbit errors, 2 out of 6 Fbit errors.Line Codes—Standard T1 line codes are supported: B8ZS, AMI, and per-channel B7ZS.Diagnostics The T1 line at each end of the link may be tested using a variety of bit patterns. In normal operation, statistics are stored for any errors occur-ring at the line interface, such as framing errors, bipolar violations, and CRC errors.Data may be looped back at the local port, through the T1 option only, and at the remote unit. Further, the unit will respond to in-band (SF) and data link (ESF) loopback codes at the local port.When in ESF framing mode, the option can automatically generate per-formance report messages.The following alarms may be monitored & logged. They may also be associated with a user-selectable indication (alarm contact or front panel LED): Remote Loopback, Lost Frame, Lost Signal, Lost Analog Signal, AIS, RAI (RYEL), MultiFrame RAI, Severely Errored Frame, Frame Re-Align, MultiFrame AIS, Far End Block Error, Line Code Error, CRC Errors and Frame Bit Error.Clocking—The clock source is configurable for network, loopback, and internal timing, with secondary selections available should the primary source become faulty.4.0 RADIO EVENT CODESTable 18 lists the event codes that may be encountered during operation of the radio. These codes may be read from a console terminal using the events pending command. (See page 43 for a full description of the events command.)NOTE: The event codes listed here are available on radios equippedwith an FT1 Option Board.

76 LEDR “S” Series I/O Guide MDS 05-3627A01, Rev. A5.0 FIELD REPROGRAMMINGThe LEDR radio’s firmware can be upgraded with new software releases that may be issued from time to time by Adaptive Broad-band/MDS. Reprogramming can be done serially through the front panel console port or over a network connection via TFTP. The TFTP method provides a way of downloading to the radio without being physically at the radio’s location.To support firmware upgrades while the radio is in use, the LEDR radio contains two complete copies of its firmware. Once the download is complete, the radio can be rebooted using the new code. However, if an error occurs during the download, the radio can easily recover because it always has a complete copy of firmware available.The steps below explain how to program new firmware into the radio using both the console port and TFTP methods.5.1 Reprogramming via the Console PortSet UpConnect a PC to the radio’s front panel console port using a 9-pin RS-232 cable. (See Figure 23 on page 85 for cable wiring details.)Download Procedure1. Start the FlashUtil Windows application available from Adaptive Broadband/MDS. From the View|Options menu, select the appropriate com port and baud rate.2. Ensure that autobaud is enabled (see lower right corner of the FlashUtil window). From the View menu, select console. This will bring up a console window to the LEDR radio. At the ADAP> prompt, enter a login name and password and then close the console. 3. Using the File|Open dialog, select the directory where the new ﬁrm-ware is located. In the ﬁle window, highlight the correct (.mpk) ﬁle and then press the green start arrow. Verification and RebootTo verify the new code, open the console again by pressing Alt + L. Enter boot to determine which image is currently active. This command will respond as follows:boot: Image 1 is Active or: boot: Image 2 is Active

MDS 05-3627A01, Rev. A LEDR “S” Series I/O Guide 77The new firmware is downloaded into the inactive image. Therefore, if the radio responded Image 1 is Active, enter iverify 2, otherwise, enter iverify 1. The radio will respond indicating whether or not the image has been verified. If the image does not verify, try downloading the code again. If the download fails after repeated attempts, the hardware may be damaged. For a replacement board please contact the factory using the information given at the back of this manual.NOTE: The following paragraph describes rebooting the radio. Thisaction will disrupt the communications link.Once the image has been verified, the radio must be rebooted using the new firmware. This is done by entering the command boot 1 or boot 2, where the 1 or 2 corresponds with the image number used with the iverify command above.Once the radio has rebooted and displays the ADAP> prompt again, the firmware can be downloaded or copied into the other image. Often, copying the firmware from one image to the other can be faster than per-forming a second download. To copy the firmware over to the other image, simply enter icopy. The radio will prompt you for confirmation (y/n) and then begin copying.5.2 Reprogramming via a Network ConnectionSet UpConnect the LEDR radio’s ETHERNET NMS connector to a PC via a net-work connection This can be done in one of three ways: 1) by con-necting both the radio and the PC to a network hub, 2) by connecting them directly through an ethernet cross-over cable, or 3) by connecting them to a common LAN.If the radio is near the PC, an RS-232 cable can be connected between them in order to run the console commands. However, if the radio is some distance away, such as at a remote site, telnet or rlogin can be used to execute the necessary commands.Download Procedure1. Log in to the radio using the login command. Use the ip command to ensure that the radio has a valid IP address. 2. "Ping" the radio from the PC to ensure that the PC and the radio have valid routes to pass information between them.3. Start a TFTP server application on the PC. At the radio’s ADAP> prompt, start the download by entering reprogram network [filename] [PC’s IP Address]. The download can be monitored from the radio by

78 LEDR “S” Series I/O Guide MDS 05-3627A01, Rev. Aentering reprogram status. When the download is complete the radio will emit two short beeps and the response from reprogram status will indicate that the download has ﬁnished.SNMP Option The TFTP download process can also be initiated using an SNMP man-ager. The Firmware|FwProgTable object provides a means for specifying the TFTP server IP address and the filename for the firmware.Verification and RebootWhen the download is complete, verify the code and reboot the radio as described under Verification and Reboot in Paragraph 5.1 above.6.0 FIELD REPLACEABLE UNITSThe Field Replaceable Units and their part numbers are listed below. Field servicing or replacement of PC boards and assemblies should be performed by qualified service personnel.When ordering parts from the factory, always give the complete model number of the radio.

The addition of an FT1 board enables the radio to operate with a G.703 interface at speeds up to 768 kbps.To add the FT1 option board to an existing LEDR II radio, follow these steps:1. Remove the top cover of the radio (4 phillips screws).

MDS 05-3627A01, Rev. A LEDR “S” Series I/O Guide 792. Locate the installation area for the FT1 option board (see Figure 21). Remove the three phillips screws on the main PC board which corre-spond to the mounting holes on the FT1 option board. 3. Install the threaded standoff spacers (furnished with the option board) onto the main PC board in the holes formerly occupied by the screws. (Note: Washers must not be used between the standoff spac-ers and either of the PC boards.)4. Locate connectors J912 and J913 (see Figure 21). These connectors mate with the plugs on the bottom of the FT1 option board.5. Carefully set the option board into place, making sure to align the mounting holes with the threaded standoffs on the main PCB. (The FT1 rear panel connector should align with the rectangular cutout at the radio’s rear panel, and the rear edge of the option board should be parallel to the main PC board.)6. Look under the right edge of the FT1 board to ensure that J912 is aligned with the mating connector on the option board. With the board properly aligned, push down ﬁrmly in the area directly above J913 and then over J912 at the edge. A distinct “snapping” action will be felt as the connectors engage.7. Install the phillips mounting screws with lockwashers on the top of the FT1 board. For protected versions only: Install the plastic clip, if supplied, at the right rear corner of the FT1 option board. It slips over the edge of the main PC board and the option board. Gently tighten the hex screw to secure the clamp.)8. Re-install the radio’s top cover. This completes the FT1 board instal-lation.

$MDS 05-3627A01, Rev. A LEDR “S” Series I/O Guide 877.3 RF Propagation PlanningEstablishing a reliable point-to-point radio link requires system plan-ning and design. It is helpful to have an understanding of the physical parameters affecting propagation. The following material discusses these factors, and will assist you in designing a dependable transmission path for your radio link.NOTE: This section is intended for use as a guideline when planningtransmission paths. It does not consider all of the local condi-tions that may be present, nor does it guarantee that adequatesignal strength will be obtained in a given system. There is nosubstitute for an on-the-air test to verify the predicted pathresults, and to check the overall operation of the radio system.To ensure a highly reliable path, a line of sight between both ends of the link is desirable. For short paths (up to 5 kilometers/3.1 miles), some obstructions may be acceptable, but the performance of a blocked path is always less predictable than a clear path.Fresnel Zone ClearanceAs the distance spanned by a link gets longer, it is necessary to have more than just a grazing path between the two ends; the path must clear the ground or other obstacles by some percentage of a Fresnel zone.The Fresnel zone corresponds to the width or girth of the radio signal. There are first, second, and third Fresnel zones, but the first zone is the only one that has substantial effects on signal strength.The first Fresnel zone can be visualized as an oval-shaped volume between two station antennas (Figure 29). As the width of the radio wave front gets blocked by obstructions, less of the signal can get to the receiver antenna.In addition to blocking the signal, obstructions in the first Fresnel zone may also cause multipath interference due to reflective and refractive signal paths. The reflected or refracted signal may arrive at the receiver out of phase with the desired signal and cause a cancelling effect.Invisible place holderFigure 29.
