View R2 CAS view

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.

Table 695 Default values of signals in R2 digital line signaling

Signal	Default rx-bits ABCD	Default tx-bits ABCD
Answer	0101	0101
Blocking	1101	1101
Clear-back	1101	1101
Clear-forward	1001	1001
Idle	1001	1001
Seize	0001	0001
Seizure-ack	1101	1101
Release-guard	1001	1001

Description Use the dl-bitscommand to configure the ABCD bit pattern for R2 signals.

Use the undo dl-bitscommand 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.
