V.35 Nx56/64 Serial Interface

The Nx56/64 serial interface operates at the following data rates: N*56K or N*64K, where N=1 to 24 (DS0s).

POWER UP TESTING & INITIALIZATION

Self-Test

When shipped from the factory, the TSU LT is set to factory default conditions. When you first power-up, the unit automatically executes self-tests followed by an initialization sequence which sets up the unit. The self-test checks the integrity of the internal operation of the electronic components by performing memory tests and by sending and verifying data test patterns through all internal interfaces. Although actual user data cannot be passed during these tests, the self-test can run with the network and DTE interfaces in place, without disturbing any external interface.

The self-test automatically executes upon power-up. It can also be commanded from a front panel menu or from the control port.

TSU LT User Manual Chapter 2 Inspection and Installation

In addition to the specified self-tests, background tests are run on various parts of the internal electronics. These run during normal operation to confirm continued correct functioning. The background tests include the following:

• Monitoring the phase-locked loop for lock.

• Standard background network performance monitoring.

The self-test works as follows:

If... Then...

a power-up (or commanded) self-test occurs the LCD displays ADTRAN TSU INITIALIZING and the LEDs

illuminate sequentially.

the self-test completes with no failures detected the LCD momentarily displays ALL TESTS PASSED.

a failure is detected it is displayed in the LCD window.

The automatic self-test consists of the following tests:

• Board level tests

• Random access memory (RAM) tests; erasable programmable read only memory (EPROM) checksum

• On-board data path. Sending a known test pattern through an on-board loop

• Unit level tests

ALTERNATE METHOD OF CONTROL FROM TSU LT

T-Watch PRO Management Software Program

T-Watch PRO is the ADTRAN management software program that allows the user to control the TSU LT from a PC. It provides complete control over the configuration of the TSU LT using a graphic interface. The T-Watch PRO program displays the same status and performance data as the front panel LCD. This data is displayed as tables and graphs. In addition, T-Watch PRO has the following capabilities:

• A modem interface permits dialing into a remote TSU LT location to configure the unit, read the unit’s status, or check its performance.

• The performance data read from the units can be exported to a file which is compatible with common spreadsheet programs.

Clock Sources and Timing

The TSU LT operates from various clock sources, permitting it to perform properly in many different applications. Use the clocking options (network, DTE, or internal timing). See the descriptions for Network Timing on page 41, DTE Timing on page 41, and Internal Timing on page 42.

The clocking option selected always designates the clock source for transmission. Clocking necessary for receiving data is always recovered from incoming data.

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. This is typically used in applications such as limited distance line drivers, where it is necessary to have the DTE as the primary clock source (see Figure 5-4).

Figure 5-4. DTE Clock Source

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.

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

Executing self-test disrupts normal data flow and prevents remote communication until the self-test is completed (approximately five seconds).

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. The remote unit will “loop” the network interface providing a path for data from the local unit over the circuit and back again. Sending a known test pattern over this loop and checking for errors verifies circuit connectivity. The following example loops the remote unit and sends a 511 pattern through the data path. Use the 511 test pattern with any T1 configuration (regardless of the channel configuration) because 511 is always sent in the occupied channels. Complete the steps outlined below to loop-up the remote TSU LT and send a test pattern.
