Submenu items do not include setting the parameters which may be necessary for a secondary interface (DS-1 Passthrough, etc.). Network (NI) Menu Items FORMAT Sets the frame format for the NI. Choices: D4 and ESF.
Chapter 5. Configuration Menu TDU 120e Clock Sources The TDU 120e is operable from various clock sources, permitting it to perform properly in many different applications. Set the network interface clocking options with the clocking options set by the Network (NI) Configuration menu options.
Chapter 5. Configuration Menu Based DS-1 The PBX is the source of timing. The TDU 120e uses the clock derived by the Base DS-1 interface for transmission timing. See Figure 5-3. OSC T1 XMIT Network Interface (DS1) T1 Receive (OPTION) Nx56/64 DS-1 DTE CLOCK DTE PBX Figure 5-3. DS-1 Timed Clock Source Base DTE Timing The Base DTE is the source of timing. The TDU 120e uses the incoming DTE clock to determine the transmission timing.
Chapter 5. Configuration Menu Internal Timing The TDU 120e is the source of timing. The TDU 120e is configured to use its own internal oscillator as the source of timing. Applications include private line driver circuits where one end is set to network and the other to internal. See Figure 5-5. OSC T1 XMIT (DS1) T1 Receive Network Interface (OPTION) Nx56/64 DS-1 DTE CLOCK DTE PBX Figure 5-5. Internal Clock Source Secondary Timing The secondary interface is the source of timing.
Chapter 5. Configuration Menu Normal (CSU) Timing The typical timing option arrangement is shown in Figure 5-7. The PBX is looped timed sending data to the TDU 120e which is actually synchronous to the received data. The Network Interface (NI) is the actual source of all timings. This timing option is the same as that typically used for CSUs. This is the preferred mode for use with a PBX application. This timing mode works equally well when the PBX is the source of timing.
Chapter 5. Configuration Menu In order to activate the -36 dB receiver sensitivity, the LBO should be set to AUTO. This feature is useful in a point-to-point application where no network elements are involved. If a network element such as a Smart Jack is installed on the circuit, the LBO should be set to 0 dB. Inband Loopback Sets unit to accept or reject the network interface loop-up and loop-down codes as defined in ANSI T1.403. Choices: Accept or Reject.
Chapter 5. Configuration Menu Init Modem Allows you to choose an industry standard or a custom initialization string for a modem connected to the control port. Choices: Industry standard and Custom Initialization String Control Port Selects the TCP/IP physical interface; Normal (10BaseT Ethernet) or SLIP using the EIA-232 serial port. Choices: Normal or SLIP If this option is set to SLIP, the EIA-232 port cannot be used as a terminal interface.
Chapter 5. Configuration Menu SLIP Flow CTL This is used to activate flow control on the Chain-In port when used as the SLIP interface. Hardware mode uses RTS and CTS. Choices: None, Hardware Proxy Traps This determines whether traps are forwarded to the IP Interface from units being “proxied” for. Choices: Enable, Disable Map Exchange The MAP EXCHANGE menu enables and sets the automatic time of day map switch.
Chapter 5. Configuration Menu Map In Use This menu item controls the DS0 map the TDU 120e uses and displays the map in current use. DS0 Maps The DS0 maps designate which DS0s are assigned to which port. The three maps are: DS0 Map A - Default Map DS0 Map B - Alternate Map Temp - Temporary map used as a scratch pad DS0 Maps Configuration Menu The DS0 maps configuration menu takes advantage of the 24-line VT 100 display.
Chapter 5. Configuration Menu You can use the up and down arrows or number keys to move the cursor from one selection to another. Press Enter to perform the action displayed to the right of the cursor. Creating a DSO Map Map configuration involves these steps. Step Explanation 1 Intializes the Temp map to one of three configurations (current Map A, current Map B, or all IDLES). This step is optional. 2 Edits the Temp map so that it reflects the desired map configuration.
Chapter 5. Configuration Menu Editing the Temp Map If further changes to the Temp map are needed, do the following: Step Action Explanation 1 Use selection 7 to enter the Temp map edit mode. Upon entering this mode, the cursor location moves to DS0 number one in the DS0 field of the Temp map. 2 Move the cursor from one DS0 to another by using the up and down arrows. Locate the DS0 number whose assigned port needs to be changed. 3 Press Enter. The cursor will move into the Port field.
Chapter 5. Configuration Menu Copying Map To copy Map A to Map B, copy Map A to the Temp Map; then apply the Temp Map to Map B. See Figure 5-9. TEMP Map A Map B Figure 5-9. DS0 Map Designations Reviewing Maps Selections 4 through 6 give a summary of the number of ports assigned to Map A, Map B, and the Temp map, respectively. The menu items and their descriptions are listed below. Copy Map A (B) to Temp Map Copies the current map A (B) into a TEMP map area.
Chapter 5. Configuration Menu Review Map A(B) Permits a quick review of the number of DS0s assigned to each port and the number of unassigned DS0s (IDLE or TST) as defined in the currently applied Map A(B). Review Temp Map This menu item is operated the same as REVIEW M AP A (B). Edit Temp Map The map in the TEMP file can be edited to whatever configuration is desired. If Map A had been copied into the TEMP file, then after editing, the TEMP file could be applied to Map A or Map B.
Chapter 5. Configuration Menu DBU config -- DBU operation Under Nx56/64 config, the menu items are: DSO Rate This sets the base rate of the interface. The actual data rate depends on the number of DS0s assigned to the Nx port. Choices: 56K or 64K TX CLK CNTRL Controls the clock used by the TDU 120e to accept transmit (TX) data from the DTE. The default is normal. If the interface cable is long, causing a phase shift in the data, the clock can be selected as INVERT.
Chapter 5. Configuration Menu “O” INHIB The Nx interface will detect an uninterrupted string of zeros (0s) being transmitted toward the network. If 0s are transmitted for >1 second, the TDU 120e will force 1s. Choices: On or Off INBAND MODE The Nx56/64 port is capable of providing an inband communications channel (for T-Watch and SNMP) between units. This is accomplished by using 8 kbps of the first DS0 assigned to that particular Nx56/64 port. If in 56 K mode, no data bandwidth will be used.
Chapter 5. Configuration Menu Dial Backup Configuration Under Dial Backup (DBU) configuration, the menu items are: Backup Mode In a backup condition, both ends of the circuit must detect backup conditions before backup is activated. One DBU is set to ORIGINATE and the other to ANSWER. Upon a network failure, only the Originate DBU initiates backup by dialing the Answer end. Once called, the Answer DBU goes into backup mode only if a backup condition is detected.
Chapter 5. Configuration Menu Restore Delay Selects the time that elapses between the network going out of alarm or data and the backup call being taken down. If N EVER is selected, the user must deactivate the backup mode. Choices: 1 sec, 3 sec, 10 sec, 30 sec, 1 min, 5 min, 10 min, never Retry Delay Selects the time between redialing the external DCE after failed dial attempts.

Chapter 6. Utility Menu To Set the Unit Identification In the UNIT ID menu under the UTIL menu, enter any value between 2 and 999. The number 1 is reserved for the PC. Pressing Enter records the Unit ID number and establishes its availability for operation by remote control. The unit proceeds to the SET CONTROL P ORT prompt. No Unit ID Desired Without entering any numbers at the UNIT ID prompt, press Enter.
Test Menu Chapter 7 The TEST menu initiates different types of unit tests and displays test results. The TEST menu contains four items. See Figure 7-1.
Chapter 7. Test Menu Executing tests will disrupt some of the normal operation. See individual menu items concerning tests before executing. Menu flow is normally depicted from left to right. At every level of the menu, pressing Escape returns the system to the previous menu level. Pressing Escape repeatedly returns the system to the Main menu. Network Tests Network tests control the activation of loopbacks and the initiation of data test patterns. Network tests are run on the Network Interface (NI).
Chapter 7. Test Menu Payload Similar to line loopback, except that the framing is extracted from the received data and then regenerated for the transmitted data. TDU 120e NI CSU Secondary Interface DS1 Payload Loopback Line Loopback Figure 7-2. Network Loopback Tests Local Loopbck There are three available choices for setting the local loopback. Line On Activates the line loopback. Payload On Activates the payload loopback. No Loopback Deactivates the loopback.
Chapter 7. Test Menu ATT In-Band LLB Activates the line loopback using inband code. ANSI FDL PLB Initiates the transmission of an FDL payload loopup code toward the far end. ANSI FDL LLB Initiates the transmission of an FDL line loopup code toward the far end. ANSI FT1 LLB Initiates the transmission of a FT1 loopback using the inband code described in T1.403. No Loopback Deactivates the loopback. Remote Loopback can only be used with Fractional T1 if the ANSI FT1 LLB is selected.
Chapter 7. Test Menu QRSS Pattern The QRSS pattern is commonly used to simulate real data in T1 interfaces. This pattern can be assigned to appear in all DS0s or only in TST DS0s. When QRSS is set in all DS0s and one of the network loopbacks previously described is activated at the far end, a total end-to-end integrity check can be run without the need for any external test equipment. When QRSS is assigned to TST DS0s, an integrity check of the link can be run along with normal data flow.
Chapter 7. Test Menu Pattern Result Displays the results of the test currently active. The process of leaving and returning to this menu item does not interrupt the test. Pressing 2 injects errors into the test pattern. These errors are detected by the device performing the pattern check. ES The number of seconds with at least 1 bit error. BES The number of seconds with more than 1 bit error and less than 320. SES The number of seconds with more than 320 bit errors.
Chapter 7. Test Menu To run an end-to-end test on Fractional DSOs, complete the following steps: Step Action 1 Set for Map B the TST in the same DS0 as used by Map A to receive data from an Nx56/64 port 2 Loop the far end usinga V.54 loopback code on the Nx56/64 port. A single DS0 can be used for continuous testing while other DS0s are passing normal data. This will also provide an end to end check on the entire link.
Chapter 7. Test Menu Upon invoking the command, the terminal displays SYSTEM SELF-TEST and the Test LEDs are illuminated. Test failures are displayed on the terminal. The self-test consists of the following: Test Name Board level tests What it does...
Chapter 7. Test Menu The execution of Port Tests will disrupt normal data flow in the port tested. Port Test Menu Items Nx/DBU (0.1) Nx/DBU (0.1) is the base Nx interface. It offers the following test functions: DTE LOOPBACK This initiates a loopback. The following options are available: PORT/LOCAL The Nx port activates both a Local loopback (back toward the DTE) and a Port loopback when either is invoked. REMOTE The remote loopback causes a channelized V.54 code to be sent to the far end.
Chapter 7. Test Menu 511 PATTRN Activates the generation of the 511 test pattern. ON The pattern check circuitry is enabled and a test started. The test is ended by selecting OFF. OFF The pattern generation and check is disabled. 511 RESULTS Displays the results of the 511 test indicated in the 511 option. The results are in the form of the number of errored seconds. The error count can be cleared by pressing C. DBU LOOPBACK ON Initiates a loopback from the DBU towards the external DCE.
Chapter 7. Test Menu DBU DATA/CNTRL Allows status of DCD and RI to be monitored while the INTERFACE TST is on. If the dial up network is correctly configured and dialed up, there should be an asterisk (*) over DCD. DBU TST RESULT When an interface test is active, this screen will show the total number of DATA blocks received and the number of blocks with errors. DS-1 (0-2) Option Ports Loopback Loopback activates the loopback function on the base DS-1 interface.

Remote/Management Menus Chapter 8 The REMOTE/MANAGEMENT menu initiates telnet/terminal sessions with remote devices and displays various management information. REMOTE MENU ACCESS This menu displays telnet menus for a remote device (may be another TSU/TDU or any other ADTRAN product that supports telnet via its EIA-232 chain port). After selecting this option, the user may choose to connect to a device entered in the Unit Access Table or enter a unit ID for a unit not in the Unit Access Table.
Chapter 8. Remote/Management Menus It is not necessary to have an entry in this table for a remote unit in order to telnet to it or forward SNMP traps from it. In the telnet case, the Remote Menu Access menu is selected from the Main menu and a unit ID is entered which may or may not be in the Unit Access Table. Units accessed via T-Watch Pro over TCP/IP use the unit ID and passcode set by T-Watch Pro running on the PC.
Chapter 8. Remote/Management Menus Table 8-1. Unit Access Commands Command Add New Unit What it does... Adds a new device to the table. You must enter a device unit ID, passcode, unit type, and polled flag. Unit type can be: Standard (which supports any TSU/TDU Multiplexer and the ISU 512), or TSU Standalone (a single port TSU with no option card slot). A passcode of 0 to 9999 for each device or DEFAULT may be selected, which results in the default passcode being used (defined as 0022 in Figure 8-1).
Chapter 8. Remote/Management Menus SNMP Read Community SNMP READ COMMUNITY NAME defaults to public. NMSs using this community name have Read access for all supported MIB objects but do not have the ability to change MIB objects. This value must be set to the same value on both the TDU 120e and the NMS (OpenView®, etc.) for the NMS to have Read access to MIBs supported by the TDU 120e. This value must be a text string of 16 characters or less.
Chapter 8. Remote/Management Menus Host 2 Trap IP Address Defaults to 0.0.0.0. Second destination address for SNMP traps. Host 3 Trap IP Address Defaults to 0.0.0.0. Third destination address for SNMP traps. Host 4 Trap IP Address Defaults to 0.0.0.0. Fourth destination address for SNMP traps. System Name A text string that can uniquely identify an SNMP managed node. The System Name is displayed at the top of each menu in telnet and terminal mode with the exception of the map editing menu.
Chapter 8. Remote/Management Menus Telnet/Terminal Timeout The TDU 120e terminates a telnet or terminal session if no activity is detected for this length of time. Only one telnet or terminal session may be active at one time. This timeout prevents an unattended session from blocking interactive access to the agent. The default value is five minutes. Telnet/Terminal Password This option allows modification of the password required for entry into a telnet or terminal session. The default value is ADTRAN.
Chapter 8. Remote/Management Menus TFTP Server File name: T120e.biz Enter the name of the upgrade file that resides on the TFTP Server. The default filename may already be correct. Begin Firmware update. Select this item and press Enter to begin the flash upgrade using TFTP. After the download is complete, the TDU 120e will close the Telnet session to reprogram the software. The Telnet session may be opened again several minutes later.

SNMP Appendix A ABOUT SNMP The term SNMP broadly refers to the message protocols used to exchange information between the network and the managed devices, as well as to the structure of network management databases. SNMP came about as local area network (LAN) environments became standardized over the past ten years and multi-vendor equipment grew with competition. It became necessary to manage the various vendor equipment from a single control console.
Appendix A. SNMP manager to retrieve or modify a particular piece of information about a network device, the network manager transmits the request to that network device. The agent in that device interprets the incoming request, performs the requested task, and sends its response to the network manager. The network manager collects all the data from the various network devices and presents it in a consistent form.
Appendix A. SNMP TDU 120e SNMP ACCESS By default, SNMP MIB Browser access to the TDU 120e IP address with the configured community names, accesses the host. The TDU 120e can also act as an SNMP proxy agent for external units. To access MIB variables on externally chained devices, append a period and the Unit ID of the device to the Read and Read/Write community names. For example: If... Then... The Read community name configured in the TDU 120e is public, Specify public.
Appendix A. SNMP SNMP Trap Configuration Traps received by the TDU 120e from external units and the host unit are converted into SNMP traps and forwarded to the configured NMS. The source of the trap is uniquely identified at the NMS by a combination of the IP address of the TDU 120e, and the Unit ID of the sending device. The Unit ID is present in the trap packet appended to the end of the trap community packet name, for example public.4.
Appendix A. SNMP SNMP MIB Browser Configuration The following steps are required to configure Network Manager MIB variable access through the TDU 120e: Step Action 1 Load the desired product MIBs on the network management station. For example: If the administrator is managing TDU 120e and ISU 512 devices, load TDU 120e.MIB, ISU512.MIB, and RFC1406.MIB. 2 Create device entries in the NMS database for all units that are to be managed through the TDU 120e.
Appendix A. SNMP SNMP MIB Files The TDU 120e supports several standard MIBs including: • MIB-II (RFC-1213), • DS1 T1/E1 MIB (RFC-1406), and • the Ethernet MIB (RFC-1643). It also supports several ADTRAN enterprise-specific MIBs including: • ADTRAN Product MIB (ADTRAN.MIB), • ADTRAN DS1 extensions MIB (ADS1.MIB), and • all TSU/TDU Enterprise MIBs, such as TDU 120e.MIB. The standard MIB files are usually included with most SNMP network management software.
