Chapter 1 Introduction 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. Communication demands of businesses continued to grow to the point that the Telcos began offering T1 service directly to the public.
Chapter 1. Introduction performance of their service offering. Since the introduction of ESF, equipment that is installed in private networks can also provide the same performance information to the user. Fractional T1 Fractional T1 lets the buyer purchase less than a full T1 circuit between two points. Most carriers offer fractional T1 in increments of 56 or 64 kbps. Connection is made to the same network elements. The network allows multiple users to share the same interoffice T1 bandwidth.
Chapter 1. Introduction TSU OVERVIEW TSU ENTER SCROLL CANCEL Figure 1-1. TSU Functional Description The ADTRAN TSU is one of several T1 multiplexers that offers complete flexibility for connection of various data sources to T1 or FT1 facilities. This family of TSU multiplexers includes the following. 1. TSU - a T1 CSU/DSU with a single NX56k/64k serial port. See Figure 1-1, above and Figure 1-2 on page 1- 4. 2.

Chapter 1. Introduction Features • A DS1 interface and an Nx56/64 DTE serial interface port. • Easy configuration capabilities using simplistic menus displayed in a Liquid Crystal Display (LCD) window operated by a front panel keypad. • Timing is selectable from the network, from the Nx56/64 DTE port, or internally. • All ones, 3:24, 511 and 1:8 Test Patterns. • Extensive self test and monitoring provides assurance of proper operation.
Chapter 1. Introduction Network Interface The Network Interface (NI) port complies with the applicable ANSI and AT&T standards. NI • AMI or B8ZS coding • Automatic or manual line build out • D4 or ESF framing • Network performance monitoring and reporting • Test loopbacks by local and remote • Extensive self test Nx56/64 Serial Interface • Data rates: N*56k or N*64k, where N=1 to 24 (DS0s) • Inverted data (Inverted HDLC) • A V.35 interface • Standard V.
Chapter 1. Introduction Three Methods of Control Front Panel The front panel provides complete and easy control of all items that can be configured through menu guided options. The front panel LCD also displays the status of operation and performance reports for the unit. A complete discussion of the operation of the front panel and all the menu options is found in Chapter 3, Operation. Adtran PC Program T-WATCH is the ADTRAN PC control program.
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. • Network • DTE Timed • Internal Timing The clocking option selected always designates the clock source for transmission.
Chapter 1. Introduction 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). See Figure 1-5. OSC T1 XMIT (DSU) T1 Receive Network Interface NX56K/64K DTE CLOCK DTE Figure 1-5.
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. OSC T1 XMIT (DSU) T1 Receive Network Interface NX56K/64K DTE CLOCK DTE Figure 1-6.
Chapter 1. Introduction 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.
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. • Payload Loopback: similar to Line loopback, except that the framing is extracted from the received data and then regenerated for the transmitted data. TSU V.
Chapter 1. Introduction 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. The DTE (or external test equipment) must provide any test pattern in order to check the DTE interface.
Chapter 1. Introduction 511 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. 1 in 8 The 1:8 pattern is used similarly to the 3:24. Each channel of the T1 has only one bit set. Application Using the V.35 DTE interface, a bridge or router can be interfaced to the network.
Installation Chapter 2 UNPACK, INSPECT, POWER CONNECTION 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.
Chapter 2. Installation Power to the TSU must be from a 115 VAC, 60Hz that is grounded. WIRING Network On the rear panel the TSU has an eight-position modular jack labeled NETWORK.
