Front Panel Description
Index Item Function
1 TEST
(button)
2 LOOP
(button)
3 TEST This 3-color LED is green when BERT is on with no errors. It flashes amber when the unit is transmitting loop or unloop code.
4 LOOP This amber LED illuminates when the unit is in any loop condition.
5 NET This 3-color LED illuminates green when the unit is in frame sync. It is red when the unit is out of sync and/or Loss of Signal.
6 ALARM This red LED illuminates when the unit is in an active alarm condition.
7 POWER This green LED illuminates when power is applied to the unit.
When this button is pushe d once, the un it transmits f i ve second s of V.54 loop code out to the ne twork. Th e indicator bl inks amber
during transmission of the loop code. When the V.54 loop sequence is finished, a 511 BERT pseudo rendom sequence is
transmitted. 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 five
seconds of V.54 loop down code and returns to normal operating mode. The TEST indicator is then turned off.
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.
It is red when the BERT is on and is receiving errors or is out of pattern sync.
