Verilink 301 (CG) Configuration/Installation Guide - Manual

Front Panel Description
1 SD Green Illuminates when the Send Data lead is a mark and is Off when the lead is a space. The LED varies from full intensity to Off depend-
ing on the relative number of marks and spaces.
2 RD Green Illuminates when the Receive Data lead is a mark and is Off when the lead is a space. The LED varies from full intensity to Off
depending on the relative number of marks and spaces.
3 IN SYNC Green Illuminates when the unit is in frame synchronization with the E1 line.
4 ERROR Red Illuminates when the internal alarm circuitry detects any of the following conditions from the incoming E1 signal: BPVs, FBEs,
CRCs, loss of signal/loss of sync, or more than 175 zeros.
5 REMOTE Red Illuminates when the internal alarm circuitry detects a remote alarm signal from the far end terminal equipment. This occurs when the
far end terminal is out of sync with the E1 signal from the network.
6 TEST Amber Illuminates when the unit is in test mode by either a manual loop switch or a test command received from the facility. When illumi-
nated, circuit 142 (TM), pin K at the digital interface is active (On).
7 RL Initiates an automated V.54 remote loop and BERT sequence of assigned data channels. The TEST LED turns green if the test is successful (the
far end unit loops and returns the data error free with the V.54 code) and red if errors are detected in the test.
NORM Switching from LL to NORM takes the unit out of test mode. Switching from RL to NORM transmits the V.54 deactivate code.
Places the unit in a local loop mode. Data from the DTE is looped back to the DTE and is also transmitted to the network (data from the network
is open). LL
