Parameter answer : Answer signal of R2 line signaling.
blocking : Blocking signal of R2 line signaling.
clear-back : Clear-back signal of R2 line signaling.
clear-forward : Clear-forward signal of R2 line signaling.
idle : Idle signal of R2 line signaling.
seize : Seizure signal of R2 line signaling.
seizure-ack : Seizure acknowledgement signal of R2 line signaling.
release-guard : Release guard signal of R2 line signaling.
received : Indicates that the signaling setting applies to received R2 line signals.
transmit : Indicates that the signaling setting applies to transmitted R2 line signals.
ABCD : ABCD bit pattern of R2 line signaling, in the range of 0000 to 1111.
Description Use the
dl-bits
command to configure the ABCD bit pattern for R2 signals.
Use the
undo dl-bits
command to restore the defaults.
This command applies to R2 signaling only.
You may need to use this command to accommodate to the ABCD bit pattern
schemes used in different countries.
When you modify the ABCD bit pattern of a signal, you need to modify the ABCD
bit pattern of other signals accordingly so that the whole signaling system can
work normally.
