ONFIGURATION
Follow these steps to configure R2 digital line signaling:
To do...
Enter system view
Enter E1/T1 interface view
Create a TS set and enable R2
signaling for it
Enter R2 CAS view
Enable the terminating point
to send answer signal
Enable the originating side to
support re-answer signal
processing
Enable the terminating point
to send clear-forward
acknowledgement signal
(clear-back signal)
Enable metering for R2
signaling
Enable the terminating point
to send seizure
acknowledgement signal
Configure the ABCD bit
pattern for each type of R2
line signal
Configure the C and D signal
bits
Configure line signal inversion
mode
Set timeout values of line
signals
