2 61220010L2-5, Issue 3 61220010L2-5C 2. OPTIONS Options and rate are selected with the front panel DIP switches as shown in Figure 1 and listed in Table 1. Customer Interface Transmit Line Build Out When -10 dB (SW1-1) is ON, the IDSL OCU-R transmits a -10 dB AMI signal across the 4-wire customer interface toward the CSU/DSU.
3 61220010L2-5, Issue 3 61220010L2-5C C A U T I O N ! SUBJECT TO ELECTROSTATIC DAMAGE OR DECREASE IN RELIABILITY. HANDLING PRECAUTIONS REQUIRED. Quality Monitor (QM) When QM (SW1-2) is ON, the IDSL OCU-R monitors the customer interface for errors.
4 61220010L2-5, Issue 3 61220010L2-5C Wiring The ADTRAN IDSL OCU-R may be mounted in any standard T400/T200 housing, or the following ADTRAN T400/T200 housings: CAUTION On span-powered units, ensure ground continuity exists between the unit, the housing, and a known approved ground source.
5 61220010L2-5, Issue 3 61220010L2-5C LED Indication The IDSL OCU-R front panel LEDs display the operating status. The LEDs are described in Table 5 . 4. TESTING Loopback Testing Loopback tests can be performed from the Central Office (CO) to verify proper loop and IDSL OCU-R operation.
6 61220010L2-5, Issue 3 61220010L2-5C IDSL/DDS Trouble Code The IDSL/DDS system provides a quick diagnosis in the case of a circuit condition where continuity is broken when the IDSL/DDS circuit uses ADTRAN U- BR1TEs with DDS Loopback capability in the central office or remote terminal.
7 61220010L2-5, Issue 3 61220010L2-5C All existing latching loopbacks can also be disabled by pressing the TEST or LBK pushbutton on the U-BR1TE or remote unit, respectively. NOTE The remote end test feature is only supported when the upstream U-BR1TE is an ADTRAN D4 or Series 5 U-BR1TE with DDS Loopback capability.
8 61220010L2-5, Issue 3 61220010L2-5C Table 8. Definition of Screen Abbreviations Abbreviation and Definition ES – Error ed Seconds: A count of the number of seconds in which at least one code violation was detected on a digital circuit. • IDSL Interface .
9 61220010L2-5, Issue 3 61220010L2-5C To conduct a terminal session, connect a VT100 or compatible test set to the OCU-R via the front panel DB-9 connector, then press the space bar three times to initiate the session. The Main Menu will appear, as illustrated in Figure 9 .
10 61220010L2-5, Issue 3 61220010L2-5C Figure 11 shows the System Status screen. Figure 12 shows Detailed Status for both network and customer loops. Figure 11.
11 61220010L2-5, Issue 3 61220010L2-5C Figure 13 shows the Loopbacks display, allowing loopback testing to be initiated or terminated while graphically displaying the testing status of the IDSL system.
12 61220010L2-5, Issue 3 61220010L2-5C Clearing PM and Event Log Registers Press “5” at the Performance Monitoring screen (Figure 14) to advance to the Warning screen (not shown). At the Warning screen the user will be prompted to clear registers; “Y” for Yes or “N” for No.

14 61220010L2-5, Issue 3 61220010L2-5C The Event Log, shown in Figure 19 , loads and time- stamps IDSL circuit performance anomalies and threshold violations. This screen is a very useful aid in troubleshooting a chronic circuit. It monitors DDS sync loss, DDS open loop, IDSL OCU-R margin, IDSL sync loss, and power-up events.
15 61220010L2-5, Issue 3 61220010L2-5C The Set Date and Time screen, Figure 21 , may be used to set the IDSL OCU-R date and time. Once the date and time are configured the performance registers date and time update accordingly.
16 61220010L2-5, Issue 3 61220010L2-5C 6. REMOTE PROVISIONING AND DIAGNOSTICS Control Protocol Remote access to provisioning and status information is accomplished using ADTRAN Digital System 6 Message protocol, defined in Control and Diagnostic Procedures Practice, Section 6032991-6.
