    Introduction Chapter 1 PRODUCT OVERVIEW The ADTRAN DSU 56/64, shown in Figure 1-1 on page 1- 2, is a technologically advanced, high performance Data Service/Channel Service Unit (DSU/CSU) that provides the interface between telco provided Digital Data Service (DDS) and the customer’s Data Terminal Equipment (DTE).
  • Page 20: Front Panel

    Chapter 1. Introduction FRONT PANEL As shown in Figure 1-1, the front panel of the DSU 56/64 contains eleven light emitting diode (LED) indicators that display DTE interface, network, and test status. These indicators are defined in the LED Identification section, below.
  • Page 21: Test Status/Error (Yellow/Red)

    Chapter 3, Test Modes on page 3-1. Test Switches The front panel also contains two push-button switches for selecting and controlling the various test modes for the DSU 56/64. The descriptions of these switches are as follows: Select Each time this switch is activated, a valid test mode is in- dicated by one or more LEDs being turned on solid.
  • Page 22: Rear Panel

    Chapter 2 in the section Configuration on page 2-2. The power cord on the rear panel of the DSU 56/64 is mechanically secured to the back panel and provides the connections to the integral AC/DC power supply.
  • Page 23: Chapter 2. Installation

    Installation Chapter 2 UNPACK, INSPECT, POWER UP Carefully inspect the DSU 56/64 for any shipping damages. If damage is suspected, file a claim immediately with the carrier and then contact ADTRAN Customer and Product Service (CAPS). If possible, keep the original shipping container for use in returning the unit for repair or for verification of damage during shipment.
  • Page 24: Power Up

    Chapter 2. Installation Power Up The DSU 56/64 is equipped with a captive six-foot power cord that is terminated with a three-prong plug for connecting to a grounded power receptacle. Ensure that a grounded, 115 VAC, 60 Hz receptacle is used for powering the DSU 56/64 unit.
  • Page 25: Antistream - Sw 3

    Antistream - SW 3 The Antistream option is used to select the antistream time out. The antistream time out is the maximum time the DSU 56/64 is allowed to transmit data from the DTE into the network. This feature prevents one DTE device on a multi-drop network from continuously tying up the transmit circuit from a remote DSU back to the master DSU.
  • Page 26: Remote Digital Loopback (Rdl) - Sw 6

    The DSU 56/64 accepts the industry standard V.54 RDL command from the far end of the circuit. Up - Disable The DSU 56/64 does not respond to the V.54 loopback command from the far end of the circuit. Loop Rate - SW 7...

    HECKSUM ALM, PTRN, and E indicators all flash at the end of the self RROR test. NEAR END TESTS The local DSU 56/64 can perform the following near end tests: • DTE Only • DTE with Test Pattern • DTE and LOOP (LL) •...
  • Page 31: Dte With Test Pattern (Tp)

    TP test is similar to the DTE O described in WITH Figure 3-1 on page 3-2. It is initiated at the local DSU 56/64 and is used to independently test the operation of the DSU 56/64. To initiate the DTE...

    DSU 56/64. DTE AND LOOP TEST (LL) This test is initiated at the local DSU 56/64 and allows independent testing of the separate sections of the DSU 56/64. This includes testing of the local DTE interface with data from the terminal or test...
  • Page 33: Figure 3-3. Dte And Loop Test Diagram

    DSU or terminal type test equipment. The DTE test splits the DSU 56/64 into separate DTE and Loop interface sections and then loops the transmit data of each interface back to its respective receive data. Figure 3-3 illustrates the loopback points and the signal paths for this test.

    EMOTE OOPBACK the loop interface and a major portion of the DTE interface of the local DSU 56/64 from the remote site over the actual digital data circuit. For the L test, the network receive data is looped to the network transmit data inside the DTE interface section of the DSU 56/64.
  • Page 35: Far End Tests

    Chapter 3. Test Modes FAR END TESTS Remote Digital When the RDL test is initiated at the local DSU 56/64, it commands the remote DSU into loopback with the industry standard V.54 loopback pattern. The loopback point and the signal paths for the...
  • Page 36: Test Pattern (Ptrn)

    Chapter 3. Test Modes Test Pattern (PTRN) When the PTRN test is initiated, the local DSU 56/64 uses the integral test pattern generator to transmit a standard 2047 test pattern to the DSU on the far end of the circuit. The local DSU 56/ 64 then examines the received data for the standard 2047 pattern.
  • Page 37: Remote Tests

    Chapter 3. Test Modes REMOTE TESTS The DSU 56/64 responds to three remotely activated tests. • Remote Digital Loopback (RDL) • CSU Loopback (LL) • DSU Loopback (RT) The RDL test is initiated by a remote DSU and causes the local DSU 56/64 to loopback.
