Choices: ENA (enable), DISA (disable) XMIT ALRM Enables and disables the transmitting of performance report message (PRM) data on the facility data link (FDL).
TSU LT User Manual Chapter 5 Config Menu Network Timing 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 looped timed as the transmission clock is derived from the received clock. See Figure 5-3. Figure 5-3. Network Timed Clock Source DTE Timing The DTE is the source of timing. The TSU LT uses the incoming DTE clock to determine the transmission timing.
Chapter 5 Config Menu TSU LT User Manual Internal Timing The TSU LT is the source of timing. The TSU LT 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. Figure 5-5. Internal Clock Source UNIT MENU Use the UNIT submenus to change control port and alarm options. Figure 5-6 shows a sample LCD window. Figure 5-6. Configuration Submenu 42 © 2003 ADTRAN, Inc.
TSU LT User Manual Chapter 5 Config Menu Cntrl Port Submenu Use to set up the unit as the master or slave on a chain of units, and to initialize a modem and the control port data rate. This option determines if the TSU LT is at the head of a chain of units (directly connected to the modem or PC). The head of the chain is referred to as the master unit. Units down the chain are referred to as slaves or a slave unit.
Chapter 5 Config Menu TSU LT User Manual Sets the telephone number to be dialed to send alarm traps. The string can be up to 20 characters in length and is terminated with a semicolon (;) as the last character. A colon (:) character is used to represent a pause in the dial string. TEL NUM For example, for number 9:5551212; dial 9, pause momentarily and then dial 5551212. This pause could be necessary to access an outside line, such as a PBX.
TSU LT User Manual START CHAN Chapter 5 Config Menu Sets the starting channel for the T1 stream. This setting must be consistent with the carrier if using a public network. Choices: 01 through 24 # OF CHAN Sets the number of DS0s (channels) to be used. The corresponding DTE rate will be this number times 56K or 64K, depending on the setting of 1)RATE 56/64. Choices: 01 through 24 DATA Controls the inversion of DTE data. This inversion can be useful when operating with an HDLC protocol.

Use SET PASSCODE to add, change, or delete a passcode. Acceptable codes are 0000 through 9999. Four question marks (????) indicate the keypad is locked. To alter the passcode, highlight PASSCODE and press ENTER. Then use the UP and DOWN arrow keys to change the digits. After changing a digit, press ENTER to move to the next digit.
Test Menu Chapter 7 The TEST submenus initiate different types of unit tests and let you view test results in the LCD window (see Figure 7-1). This menu contains three branches: NETWORK TEST, RUN SELFTEST, and PORT TESTS. Test execution will disrupt some of the unit’s normal operation. See individual menu items concerning tests before executing. NO LOOPBACK 1) LOCAL LOOPBK LINE ON NO LOOPBACK PAYLOAD ON V.
Chapter 7 Test Menu TSU LT User Manual PAYLOAD ON. Figure 7-2 shows an illustration of how the tests work. No Loopback Deactivates the loopback. Line On Activates the line loopback which loops all of the received data back toward the network. The transmitted data is the identical line code that was received, including any bipolar violations or framing errors.
TSU LT User Manual Chapter 7 Test Menu Test Pattern Selects the test pattern and initiates the transmission of the pattern. There are five patterns available (see below). End testing by selecting NO PATTERN. 1:8 ALL DS0s Generates a 1 in 8 pattern in all DS0s. 511 Active DS0s Generates a 511 test pattern and inserts the pattern into currently active channels. All Zeros Generates an all zero's pattern in every channel. All Ones Generates an all one’s pattern in every channel.
Chapter 7 Test Menu TSU LT User Manual The self-test includes the following board-level tests, in this order: 1. RAM tests; EPROM checksum 2. On-board data path; sending a known test pattern through an on-board loop 3. Front panel LED verification 4. Phase lock loop verification. If a failure is detected, note the failure number and contact ADTRAN Technical Support.
Chapter 8 Circuit Testing Before using the TSU LT to pass data, ADTRAN recommends running tests on the circuit. Testing consists of sending a test pattern from end-to-end and checking for errors in the pattern. There are two types of tests used to accomplish this: 1. Loop-up the far end and then send a test pattern. 2. Send a test pattern from both ends and check at both ends. Far End Looped Back Test TSU LTs should respond to a loop-up code sent over the T1 circuit.
Chapter 8 Circuit Testing TSU LT User Manual Ending the Test When you have finished viewing the results, complete the following steps to return the TSU LT to normal operation: 1. Press CANCEL to return to submenu item TEST PATTERN. 2. Select NO PATTERN to terminate the test and the 511 pattern generation. Result: The far end remains in loopback until the network REMOTE LOOPBK is set to NO LOOPBACK under submenu item REMOTE LOOPBK. 54 © 2003 ADTRAN, Inc.
