Front Panel Description
1 Status: The green LED lights when the unit is powered and operati on is norm al. The red LED lights if an alarm exceeding thresholds is detect ed.
2 ACO: This ye llow LED lights if the A la rm Cut Off switch is placed in the left ON position. It indica te s 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 posi ti on, thi s ci rcuitry is deactivated.
4 BV/CR/FE: This LED lights one second for each seco nd that has an occurrence of bipolar violations, cyclic redundancy check errors, or frame bi t 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 one s condition (alarm indic at ion 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 unti l the Alarm Reset Timer pe riod ends.
9 DENSITY: This LED light s w hen the ones densit y requirement of the r ec eived equipment signal i s be l ow the minimum.
10 LLB: This LED lights co nt inuously when the network interface is in a line loopback. It flashes when the D TE interface is in a line loopback.
11 PLB: This LED lig hts continuously when the network interface is in a payload loopback.
12 TST: This LED lights continuously during a far or loca l te st. It fl ashes when loop codes are transmitted at the start of a far test and when unloop codes are
transmitted at th e en d 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 tr ans mitting IBLC, th e test LED blinks. I f transmitting a te s t pa ttern, 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 signal s passing through the unit, and the bottom two port s br eak connection to the unit and make connecti on to the DTE.
16 Activity LEDs: These two small, recessed LEDs are provided to indicate supervisory and NMS port activity.
17 SUPV: This 6-pi n supe rvi sory jack provides direct term inal access for CSU contr ol and ga thers status/facility perfo rmance data. Refer to the table above.
18 Pattern Sele ct: T his rotary switch determ ines the BERT pattern sent by the unit when the test swit ch (item 14) is in the FAR position. Refer to the table above.
