Front Panel Description

1 Status: The green LED lights when the unit is powered and operation is normal. The red LED lights if an alarm exceeding thresholds is detected.

2 ACO: This yellow LED lights if the Alarm Cut Off switch is placed in the left, ON position. It indicates that the alarm relay contacts are disabled.

3 ACO SW: This switch controls the alarm relay circuitry. If the switch is placed in the left ON, position, this circuitry is deactivated.

4 BV/CR/FE: This LED lights one second for each second that has an occurrence of bipolar violations, cyclic redundancy check errors, or frame bit errors.

5 LOS/OOF: This LED blinks with loss of signal (LOS) from the network or DTE. It lights constantly when an out of frame (OOF) condition is detected.

6 AIS: This LED lights if an unframed all-ones condition (alarm indication signal) is detected from the network or equipment.

7 REM ALM: This LED lights constantly when a yellow alarm signal is received from the far end.

8 LOC ALM: This LED lights when a local alarm exceeding alarm thresholds exists. It remains lit until the Alarm Reset Timer period ends.

9 DENSITY: This LED lights when the ones-density requirement of the received equipment signal is below the minimum.

10 LLB: This LED lights continuously when the network interface is in a line loopback. It flashes when the DTE interface is in a line loopback.

11 PLB: This LED lights continuously when the network interface is in a payload loopback.

12 TST: This LED lights continuously during a far or local test. It flashes when loop codes are transmitted at the start of a far test and when unloop codes are

transmitted at the end of a far test.

13 ERR: This LED lights for one second when BERT pattern errors are received during a Far test.

14 Test Switch: This switch is used for local testing. If transmitting IBLC, the test LED blinks. If transmitting a test pattern, it lights continuously.

15 Test Jacks: Provides access to the T1 line on the DTE side – the top two jacks break connection to the DTE and make connection to the unit in the direction of the

network, the middle two ports monitor the signals passing through the unit, and the bottom two ports break connection to the unit and make connection to the DTE.

16 Activity LEDs: These two small, recessed LEDs are provided to indicate supervisory and NMS port activity.

17 SUPV: This 6-pin supervisory jack provides direct terminal access for CSU control and to gather status/facility performance data. Refer to the table above.

18 Pattern Select: This rotary switch determines the BERT pattern sent by the unit when the test switch (item 14) is in the FAR position. Refer to the table above.
