Front Panel Description
Index Item Function
1 TEST When this button is pushed once, the unit transmits five seconds of inband loop code out to the network (either LLB or V.54
depending on Switch S1-7). The indicator blinks gree n during tra nsmission of the lo op code. If S witch S2-8 is set to Clear Loop,
the data from the DTE is passed to the network and data from the network is passed to the DTE. The TEST indicator is solid
green in this mode. If Switch S2-8 is set to BERT, the test pattern last selected is transmitted toward the network. The received
pattern is compared and if it is error free, the TEST indicator remains green. If pattern errors are detected, the TEST indicator
turns red for a minimum of one second. If the TEST button is pushed again, the unit transmits 5 seconds of inband loop down
code and returns to normal operating mode. The TEST indicator is then turned off.
2 LOOP When this button is pressed once, the unit activates a line loopback, looping the network receive data back to the network, and
looping the data from the DTE ports back to the DTE. The LOOP indicator is lit while the unit is in loop. If pushed again, the
unit clears the loop and turns off the LOOP indicator.
3 TEST This 3-color LED flashes green when the unit is transmitting loop code. It is green continuously when BERT is on with no
errors or the unit is in a clear test. It is red when the BERT is on and is receiving errors.
4 LOOP This amber LED lights continuously when the unit is in any loop condition.
5 NET This 3-color LED is green when the unit is in frame sync. It is amber when the unit is receiving a yellow alarm from the far en d.
It is red when the unit is out of frame sync.
6 ALARM This red LED lights continuously when the unit is in an active alarm condition. It flashes if the switch configuration is invalid.
7 POWER This green LED lights continuously when power is applied to the unit.
