Chapter 1.
Chapter 1. Introduction Interfaces The TSU 120 base unit is equipped with a slot in the rear panel to house option modules which provide a variety of additional data ports. See Figure 1-3. The base unit is equipped with the following five interfaces: • Network DSI interface per AT&T 61402 • DSX-1 (PBX) • Nx56/64 serial V.
Chapter 1. Introduction TSU 120 INTERFACES The Network Interface (NI) port complies with the applicable ANSI and AT&T standards. Network Interface The NI provides the following functions: • AMI or B8ZS coding • Automatic or manual line build out • D4 or ESF framing • Network performance monitoring and reporting • Test loopbacks with QRSS generation and checking • Extensive self test DSX-1 (PBX) Interface The DSX-1 interface provides the following functions: • DSX-1 per ANSI T1.
Chapter 1.
Chapter 1. Introduction OPTION PORTS The option ports vary depending on the option modules installed. Secondary Interfaces (SI) The secondary interface is an additional interface to a DS1, a DSX1 facility, or some other network service, and it offers a source of timing. The type of interface depends on the option module installed. The interface includes the following: • DSX1 An additional DSX-1 interface can be added for data or voice applications.
Chapter 1. Introduction FOUR 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 the chapter, Operations. ADTRAN PC Program T-Watch is the ADTRAN PC control program.
Chapter 1. Introduction TSU 120 CLOCK SOURCES The TSU 120 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 clocking options set by using the Network (NI) Configuration menu options.
Chapter 1. Introduction DSX-1 Timed The PBX is the source of timing. The TSU 120 uses the clock derived by the Base DSX-1 interface for transmission timing (see Figure 1-5). The Base DSX-1 source timing is restricted from use when a secondary interface is used at the same time. OSC T1 XMIT (DS1) T1 Receive Network Interface (OPTION) Nx56/64 DSX-1 DTE CLOCK DTE PBX Figure 1-5 DSX-1 Timed Clock Source 12 TSU 120 User Manual 61200.
Chapter 1. Introduction DTE Timed The DTE is the source of timing. The TSU 120 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 1-6. The DTE source timing is restricted from use when a secondary interface is used at the same time.
Chapter 1. Introduction Internal Timing The TSU 120 is the source of timing. The TSU 120 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 1-7. The internal source timing is restricted from use when a secondary interface is also used.
Chapter 1. Introduction Normal (CSU) Timing The typical timing option arrangement is shown in Figure 1-8. The PBX is looped timed sending data to the TSU 120 which is actually synchronous to the received data. The Network Interface (NI) is the actual source of all timings. This timing option is the same as that typically used for CSUs. This is the preferred mode for use with a PBX application. This timing mode works equally well when the PBX is the source of timing.
Chapter 1. Introduction TSU 120 TESTING The TSU 120 offers three forms of testing: • Self test • Loopback tests (local and remote) • 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 Additionally, the loopbacks can be remotely controlled by out-of-band commands through the T1 ESF FDL or from T-Watch through a modem connection. Classes of Loopbacks There are two classes of loopbacks: network interface and DTE interface. Network Interface Loopbacks Network interface loopbacks (see Figure 1-9) affect the entire T1 data stream. There are two types of network loopbacks, line loopback and payload loopback.
Chapter 1. Introduction DTE loopback loops all data from the DTE back towards the DTE. This loopback occurs just past the interface circuit allowing a verification of the operation of the DTE to TSU 120. This loopback may be initiated by using front panel or T-Watch commands. The DTE (or external test equipment) must provide anytest pattern to check the DTE interface. See Figure 1-10. The TSU 120 also activates a port loopback when the DTE loopback is asserted.
Chapter 1. Introduction TSU 120 Nx56/64 T1 Network Interface (NI) Interface Nx56/64 to Network Control Circuit Port Loopback to DTE Figure 1-11 Port Interface Loopback DSX-1 Interface Loopbacks Line Loopbacks On the DSX-1 interface, the line loopback causes data received at the DSX-1 to be looped back toward the PBX achieving a local loopback. Port Loopback The port loopback is internal and loops all data mapped to the DSX-1 back toward the network interface on the controller.
Chapter 1. Introduction TSU 120 DSX-1 Interface T1 Network Interface (NI) (Controller) DSX-1 PBX PORT LINE LOOPBACKS Figure 1-12 Diagram of Loopbacks Pattern Generation The TSU 120 offers two available test Patterns: QRSS and 511. QRSS Pattern The QRSS pattern is commonly used to simulate real data in T1 interfaces. This pattern can be assigned to appear in all DS0s or only in TST DS0s.
