LOOP lS DOWN The 2-wire loop is not activated.
ADR# LOOP BACK A distant unit with address # is in a loopback commanded from this card.
NT1 LOOP BACK The NT1 is in loopback as commanded from this card.
B1 LOOP BACK This card is currently looping back channel B1 as commanded from a far unit.
B2 LOOP BACK This card is currently looping back channel B2 as commanded from a far unit.
2B+D LOOP BACK This card is currently looping back all channels as commanded from a far unit.
BANK CR FAIL Bank carrier fail, the channel bank is not receiving data from the T carrier.
XMIT CR SIDE Transmit carrier side, forcing the injection of 64 kbps data into a Bearer channel from the front panel Bantam jack into the carrier direction.
XMIT LP SIDE Transmit loop side, forcing the injection of 64 kbps data into a Bearer channel from the front panel Bantam jack into the loop direction.
MADE B1 LPBK Made B1 loopback, manually forced the Bearer channel B1 loopback in both the network and customer directions.
MADE B2 LPBK Made B2 loopback, manually forced the Bearer channel B2 loopback in both the network and customer directions.
CHCK TEST SET Check test set, ensure test set Tx probe is properly inserted into faceplate Bantam jack and configured as NEAR LOGIC.
