Chapter 5. Configuration Menu NETWORK (NI) This menu item accesses the configuration of parameters associated with the network interface in the base unit. There are nine submenu items that include setting the format, the line build out (LBO), and the timing mode. Submenu items do not include setting the parameters which may be necessary for a secondary interface (DSX-1 Passthru, etc.). Network (NI) Menu Items The menu items are: Menu Item FORMAT Description Sets the frame format for the NI.
Chapter 5. Configuration Menu Menu Item SET LBO Description Selects the line build out for the network interface. In the TSU 120 sets the LBO based on the strength of the receive signal and displays the selected value. AUTO MODE, Choices: 0.0 dB, 7.5 dB, 15 dB, 22 dB, Auto. 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.
Chapter 5. Configuration Menu TSU 120 Clock Sources The TSU 120 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 Network Timed The network is the source of timing. The received data clocking is looped back to the network where it is used to determine the transmission timing. This option is also referred to as loop timed as the transmission clock is derived from the received clock. See Figure 5-2. . Figure 5-2.
Chapter 5. Configuration Menu Base DSX-1 Timing The PBX is the source of timing. The TSU 120 uses the clock derived by the Base DSX-1 interface for transmission timing. See Figure 5-3. OSC T1 XMIT (DS1) T1 Receive Network Interface (OPTION) Nx56/64 DSX-1 DTE CLOCK DTE PBX Figure 5-3.
Chapter 5. Configuration Menu DTE Timing The DTE is the source of timing. The TSU 120 uses the incoming DTE clock to determine the transmission timing. This is typically used in applications where it is necessary to have the DTE as the primary clock source, (such as limited distance line drivers). See Figure 5-4. OSC T1 XMIT (DS1) T1 Receive Network Interface (O P T I O N) Nx56/64 DSX-1 DTE CLOCK DTE PBX Figure 5-4.
Chapter 5. Configuration Menu Internal Timing The TSU 120 is the source of timing. The TSU 120 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 DSX-1 DTE CLOCK DTE PBX Figure 5-5.
Chapter 5. Configuration Menu Secondary Timing The secondary interface is the source of timing. The TSU 120 uses the clock derived by the secondary interface for transmission timing and the receive signal timing. See Figure 5-6. Either a DSX-1 Option Module or a Drop and Insert Option Module must be installed in the TSU 120 for this mode to function. OSC T1 XMIT (DS1) T1 Receive Secondary Interface (SI) Network Interface (NI) (IO PB) ( OPT IO N ) PBX Nx56/64 DSX DTE CLOCK DTE PBX Figure 5-6.
Chapter 5. Configuration Menu Normal (CSU) Timing In the Normal (CSU) Timing mode, the Receive Clock is derived from the Network Interface while the Transmit Clock is derived from the PBX or other alternative timing source, connected to the Secondary Interface (e.g., Drop and Insert or DSX-1). See Figure 5-7. This timing option is the same as that typically used for CSUs. This is the preferred mode for use with a PBX application. Secondary Interface (SI) Network Interface (NI) (OPTION) Figure 5-7.
Chapter 5. Configuration Menu Unit Menu The Unit menu changes the baud rate of the chain in port and the setup of the dial out port. The menu items are: Menu Item Description Sets the baud rate for communication with the PC or modem. CTL PORT RATE Choices: 1200, 2400, 9600, 19200, and 38400 kbps Enables or disables the transmission of trap messages.
Chapter 5. Configuration Menu Menu Item IP ADDRESS Description This is the IP address that uniquely identifies the TSU 120 on a TCP/IP network. This address is composed of four decimal numbers, each in the range of 0 to 255, separated by periods. This value is used for either the 10BaseT Ethernet or SLIP interface, depending on the IP interface setting (10BaseT is only available in the TSU 120e). SUBNET MASK This defines which part of a destination IP address is the Network number.
Chapter 5. Configuration Menu Map Exchange (Map Xchng) The MAP EXCHANGE menu enables and sets the automatic time of day map switch. The unit provides selection of the hour, minute, and seconds for the map switching to take place. The menu items are: Menu Item Description OFF Indicates the map in use does not change (disabled). AUTO Indicates that the map in use will change at a user-selected time of day (enabled). 1. Scroll to select AUTO to enable or OFF to disable the Automatic Map Change feature.
Chapter 5. Configuration Menu DS0 Map A and DS0 Map B The DS0 maps designate which DS0s are assigned to which port. See Figure 5-8. There are three maps, DS0 MAP A, DS0 MAP B, and the TEMPORARY (TEMP) MAP. TEMP MAP A MAP B Figure 5-8. DS0 Map Designations Map A and Map B are the current maps the TSU 120 uses. The Temp map generates a map before putting it into use. You can copy Map A to Map B by copying the Map A into the TEMP map. Then apply (write) the TEMP map into Map B.
Chapter 5. Configuration Menu Menu Item Description REVIEW TEMP This menu item is operated the same for the Temp Map as is 3)REVIEW MAP A or MAP B. EDIT TEMP 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. The menu operation is identical to 2) CREATE TEMP with the exception that the existing port selections display.
Chapter 5. Configuration Menu With the cursor on CREATE TEMP, press Enter. The unit displays the selection screen with the cursor positioned on the first selection DS0 number. See Figure 5-9. Select DS0 Number Select Port Figure 5-9. Create Temp Selection Screen 1. Use either the Arrow Keys or Numbers to enter the DS0 number (do not mix the use of the keys). 2. Press Enter to complete the selection and move the cursor to Port, the next field. 3.
Chapter 5. Configuration Menu Port Configuration (Port Config) Port Configuration selects and configures the parameters associated with any data port in the unit. For example, parameters for the DSX-1 (PBX) interface are set through this menu. The items that can be set depend on which option module is installed. The list of option ports will vary with the configuration.
Chapter 5. Configuration Menu Menu Item DATA Description Used to control the inverting of the DTE data. This inversion can be useful when operating with an HDLC protocol. Often used as a means to ensure 1s density. Choices: Normal, Invert If Invert is selected, zero (0) inhibit should also be selected to prevent an open DTE input from placing zeros on the network. CTS Used to control characteristics of CTS. Choices: Normal*, Force On *See Table 5-1 on page 5-20. DCD Data Carrier Detect.
Chapter 5. Configuration Menu Menu Item INBAND MODE Description The Nx56/64 port is capable of providing an inband communications channel (for TWatch 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. Inband must also be enabled at the destination port.
Chapter 5. Configuration Menu DBU Configuration Menu Items (TSU 120e only) Menu Items BACKUP MODE Description 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. This is ideal for controlling where calls originate.
Chapter 5. Configuration Menu Menu Items Description RESTORE DELAY Selects the time that elapses between the network going out of alarm or data and the backup call being taken down. If NEVER 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.

Appendix A Understanding SNMP ABOUT SNMP As local area network (LAN) environments became standardized over the past ten years, multi-vendor equipment grew with competition. It became necessary to manage the various vendor equipment from a single control console. Thus, the SNMP emerged as the standard for managing commercial TCP/IP networks.
Appendix A. Understanding SNMP MIB This is an index to the organized data within a network device. It defines the operating parameters that can be controlled or monitored. When requesting the network 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.
Appendix A. Understanding SNMP Trap This is an unsolicited message issued by a network device to report an operational anomaly or an alarm condition to the network manager. These messages are typically encased within informational packets and transported over the LAN or WAN (wide area network). TSU 120 SNMP Access By default, SNMP MIB Browser access to the TSU 120 IP address with the configured community names, accesses the host. The TSU 120 can also act as an SNMP proxy agent for external units.
Appendix A. Understanding SNMP SNMP Trap Configuration Traps received by the TSU 120 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 TSU 120, 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. Understanding SNMP SNMP MIB BROWSER CONFIGURATION The following steps, shown in Table A-1 are required to configure Network Manager MIB variable access through the TSU 120: Table A-1. How to Configure Network Manager MIB Step Action 1 Load the desired product MIBs on the network management station. If, for example, the administrator is managing TSU 120 and ISU 512 devices, load TSU 120.MIB, ISU512.MIB, and RFC1406.MIB.

Appendix B Understanding TR-08 The TSU 120 chassis functions as a Remote Terminal in Digital Loop Carrier and as Integrated Digital Loop Carrier Systems as described in TR-TSY 000008. The TSU 120 supports SLC96 framing, Mode I operation, ORB-13 and ORB-16 alarm formats, alarm reporting, and user-definable BPV threshold detection rate.
Appendix B. Understanding TR-08 Table B-1 explains what conditions trigger alarms and how alarms are processed when received by the TSU 120. Table B-1. Alarm Conditions Name Explanation FELP When the TSU 120 receives a FELP alarm, it will loop the incoming data directly to the outgoing data. LINE ON is placed in history. The alarms and loopback are cleared when FELP is no longer received. Loss of Data The TSU 120 will send MINOR ALARM and the A SHELF ALARM for 2.
