1
Status: This green LED lights when the unit is powered and operating normally. The red LED lights if the alarm card circuitry detects an alarm condition from the
FAR, NET, or DTE indicators or if an alarm threshold has been exceeded (if equipped with optional alarm card).
2
ACO: This red LED (only on units equipped with the optional alarm card) lights if the ‘alarm cut off’ switch is placed in the left ‘ON’ position. This indicates that
the alarm relay contacts are disabled.
3
ACO SW: The alarm cut off switch controls the alarm relay circuitry. It is disabled in the left ‘ON’ position. The right ‘OFF’ position enables alarm reporting.
4
Switch S1: This 7 - position DIP configuration switch is described on the reverse side.
5
Switch S2: This 7 - position DIP configuration switch is described on the reverse side.
6
Net Error: This LED lights a minimum of 0.1 second if the internal alarm circuitry detects any of the following conditions from the incoming T1 signal – one or
more bipolar violations (BPV), frame bit errors (FBE), cyclic redundancy check errors (CRC), or a loss of signal/out of frame (LOS /OOF) condition.
7
Far Error: This LED lights a minimum of 0.1 second if the internal alarm circuitry detects a yellow alarm signal from the far end terminal equipment. This
condition occurs if the far end terminal is out of sync with the T1 signal from the network.
8
DTE Error: This LED lights a minimum of 0.1 second if the internal alarm circuitry detects any one of the following conditions from the DTE – one or more
bipolar violations (BPV), frame bit errors (FBE), cyclic redundancy check errors (CRC), yellow alarm, low one’s density, or a loss of signal/out of frame condition.
9
Loop: This LED lights under the following conditions – the manual loop switch is in the ‘LOOP’ position, the unit receives an inband loop code for more than 5
seconds, or the unit receives an FDL loop message (PLB or LLB). The LED does not light if the test switch is placed in the ‘NRM’ position or if an inband or FDL
unloop code is received.
10
Test Switch: This switch is used for local testing. In the local loop mode (LOOP), the unit loops the signal from the customer equipment (DTE in) back to the
customer equipment (DTE out). It also loops the received signal from the T1 facility (NET IN) back to the T1 facility (NET OUT). When moved back to ‘NRM’,
the local loopback is removed.
11
Test Jacks: These bantam jacks provide access to the T1 line on the DTE side as follows – the top 2 jacks break connection to the DTE and make connection to the
unit in the direction of the network, the middle 2 ports are used for monitoring the signals passing through the unit (between the DTE and the network), and the
bottom 2 ports break connection to the unit and make connection to the DTE.
