Page 17: Chapter 1. Introduction
Chapter 1 T1/FT1 OVERVIEW T1 digital communication links have been used by the transmitting companies (Telcos) for the transmitting of voice since the early sixties. The D4 channel bank is an example of a T1 digital carrier system that was introduced in the mid seventies and is still widely used by the Telcos. -

Chapter 3, Operation. Adtran PC Program T-WATCH is the ADTRAN PC control program. It provides complete control over the configuration of the TSU using a graphic interface. The T-WATCH program displays the same status and performance data as the front panel LCD. -
Page 24: Tsu Clock Sources
Chapter 1. Introduction TSU Clock Sources The TSU is operable from various clock sources permitting it to perform properly in many different applications. The network interface clocking options are set by using the Network (NI) Configuration menu options. There are three clock source options available. -
Page 25: Dte Timed
DTE Timed The DTE is the source of timing. The TSU 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). -
Page 26: Internal Timing
Chapter 1. Introduction Internal Timing The TSU is the source of timing. The TSU 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 1-6. -
Page 27: Tsu Testing
TSU Testing Currently the TSU offers three forms of testing. • Self Test • Loopback Tests • Pattern generation and check Self Tests 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. -
Page 28: Network Loopbacks
Chapter 1. Introduction Network Loopbacks There are two types of network loopbacks; see Figure 1-7. • Line Loopback: 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. -
Page 29: Dte Interface Loopbacks
DTE Interface Loopbacks The Nx56k/64k serial interface offers a DTE loopback. See Figure 1-8. DTE Loopback: loops all data from the DTE back towards the DTE. This loopback may be initiated by the DTE asserting the Local Loopback (LL) input on the connector or by using front panel or T-WATCH commands. -
Page 30: Application
Chapter 1. Introduction 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 as previously described, an end to end integrity check can be made on the DTE ports. -
Page 31: Chapter 2. Installation
Carefully inspect the TSU for any shipping damages. If damage is suspected, file a claim immediately with the carrier and then contact ADTRAN Customer and Product Service. If possible, keep the original shipping container for use in shipping the TSU back for repair or for verification of damage during shipment. -
