Page 26: Control Port Input
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.
Page 27: Self-Test
TSU LT User Manual Chapter 1. Introduction Self-test 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 and without disturbing any external interface.
Page 28: Dte Interface Loopbacks
Figure 1-6. DTE Interface Loopback Pattern Generation The TSU LT offers four available test patterns: 511, 1:8, All Ones, and All Zeros. The 511 pattern is generated and checked by the Nx56K/64K serial interface. It only appears in the DS0s assigned to the Nx56K/64K port. When used in conjunction with the payload loopback at the far end, an end-to-end integrity check can be made on the DTE ports.
Page 29: Bridge/Router Application
TSU LT User Manual Chapter 1. Introduction Bridge/Router Application A bridge or router can be interfaced to the network by using the V.35/V.11 DTE interface. The bandwidth used is programmable at Nx56 or Nx64 data rates for T1 or FT1 service. The bandwidth can be selected as contiguous or alternate.
Page 31: Chapter 2 Installation
Power to the TSU LT must be from a grounded 220-230 VAC, 60 Hz power source. Power Up Testing and Initialization When shipped from the factory, the TSU LT is set to factory default conditions. At the first application of power, the unit automatically executes self-tests followed by an initialization sequence which sets up the unit.

Operation Chapter 3 OPERATION The TSU LT can be configured and controlled from either the local front panel or from a PC using the T-Watch Management Software Program. General Menu Operation The TSU LT uses a multilevel menu structure containing both menu items and data fields. All menu operations and data are displayed in the LCD window.

Page 45: Figure 5-3. Network Timed Clock Source
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.
Page 46: Figure 5-4. Dte Clock Source
Figure 5-4. DTE Clock Source 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.
Page 47: Unit
POSITION OF TSU LT Determines if this 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.

, the first DS0 occupied operates in 56K mode and the DTE clock rate is reduced by 8 kbps. The TSU LT uses this 8 kbps channel to send and receive configuration data across a T1 span. As shown in Figure 5-7, this allows the PC connected to the chain-in port on TSU LT A to monitor/configure both TSU LT A and B.
