R2511-HP MSR Router Series Voice Command Reference(V5)

133
reverse
NOTE:
This command applies to R2 signaling only.
Use reverse to configure line signal inversion mode.
Use undo reverse to invert ABCD bits of the current line signaling whose values are "1" after the reverse
command is executed.
Syntax
reverse ABCD
undo reverse
Views
R2 CAS view
Default command level
2: System level
Parameters
ABCD: Indicates whether corresponding ABCD bits in R2 signaling need inversion. Each argument in
this command takes either of the two values: 0 for normal or 1 for inversion. The default is 0000, that is,
inversion disabled.
Usage guidelines
Configure an interface to invert the values of any ABCD bits before sending or after receiving a line
signal by replacing 0 with 1 or vice versa.
Examples
# Invert the values of bits B and D in R2 line signaling.
<Sysname> system-view
[Sysname] controller e1 1/0
[Sysname-e1 1/0] timeslot-set 0 timeslot-list 1-31 signal r2
[Sysname-e1 1/0] cas 0
[Sysname-cas1/0:0] reverse 0101

NOTE:
This command applies to R2 signaling only.
Use seizure-ack enable to configure the originating side to require the terminating side to send seizure
acknowledgement signal during R2 line signaling exchange.
Use undo seizure-ack enable to restore the default.
