cnfds0localcas
cnfds0localcas
To configure a local channel associated signaling (CAS) 4-bit pattern for a T1 line and DS0, use the
cnfds0localcas command in the VoIP switching/trunking, switched AAL2 PVC, and AAL2 trunking
operating modes.
cnfds0localcas line-num ds0-num local-cas-enable |local-cas-pattern|
Syntax Description
Command Modes VoIP switching/trunking, switched AAL2 PVC, and AAL2 trunking
Usage Guidelines If a DS0 is configured for local CAS, the framer forces the CAS bits to a value defined by the
local-cas-pattern argument in this command.
This command is not allowed if any of the following conditions are pr e sen t:
•The line signaling type is CAS.
•The line is not enabled.
•The DS0 is in a remote loop state.
Note This command is allowed for T1 lines only.
Examples The following example shows that T1 line 2, DS0 number 12 is configured with a local 4-bit pattern
represented by a value of 3 (0011 in binary):
cnfds0localcas 2 12 1 3
line-num T1 line number on which to configure a local CAS bit pattern; in the range
from 1 to 8.
ds0-num DS0 number on which to configure a local CAS bit pattern. It ca n be a value
from one of the following ranges:
•1 to 24 for T1 lines
•1 to 31 for E1 lines
local-cas-enable Enables or disables the local CAS pattern indicated by the local-cas-pattern
argument. It can be one of the following values:
•1 = Enabled
•2 = Disabled
local-cas-pattern (Optional) The local 4-bit patte rn expressed as a nu mber in th e range fro m 1
(default) to 15. The value specifies, in binary, the value of the A, B, C, and D
signaling bits.
Note If local CAS is enabled (local-cas-enable argument = 1), this argu ment
is mandatory.
