  • Page 25: Tsu 120 Clock Sources

    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.

  • Page 26: Dsx-1 Timed

    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 trans- mission 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.

  • Page 27: Dte Timed

    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).

  • Page 28: Internal Timing

    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.

  • Page 29: 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.

  • Page 31: Classes Of Loopbacks

    DTE interface loopbacks affect only that portion of the data stream programmed to that particular interface port. The Nx56/64 serial interface offers two loop- backs, a DTE loopback and a port loopback. See Figures 1-10 and 1-11. 61200.129L1-1 TSU 120 User Manual...

  • Page 32: Figure 1-10 Dte Interface Loopback

    DTE. This loopback occurs just past the interface circuit allowing a verification of the opera- tion 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.

  • Page 33: Dsx-1 Interface Loopbacks

    (BERT) to drive the network interface, exercises the entire data path from the network interface (NI) controller, through the DSX-1 interface, and back out the network interface controller. See Figure 1-12. To deactivate the loopback, select None under the 0.2 DSX-1 submenu. 61200.129L1-1 TSU 120 User Manual...

  • Page 34: Pattern Generation

    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.
