Configure Advanced Trunk Voice Port Parameters
It is the same as creation of E1 trunk voice port, and for T1 CAS signaling,
and the following advanced setting is possible.
T1-CAS Bit Modification Settings
The bit modification commands for digital voice ports modify sent or received
bit patterns. Different versions of E & M use different ABCD signaling bits to
represent idle and seize. For example, North American CAS E & M represents
idle as 0XXX and seize as 1XXX, where X indicates that the state of the BCD
bits is ignored. In MELCAS E & M, idle is 1101 and seize is 0101.
The commands in this section are provided to modify bit patterns to match
particular E & M schemes.
To manipulate bit patterns for trunk voice ports, use the following commands
as necessary, in voice-port configuration mode:

Purpose
To set up the attribute values of created ds0-
group, starts with voice-port configuration mode.
if ds0-group was created normally, there is no
error in this CLI command.
Shuts down the voice port to manipulate
'timeslots' and 'signal cas' command.
Manipulates sent or received bit patterns to
match expected patterns on a connected
device. Repeat the command for each transmit
and/or receive bit to be modified, but be careful
not to destroy the information content of the bit
pattern.
The default is that the signaling format is not
manipulated(for all transmit or receive A, B, C,
and D bits).
on-Sets the bit to 1 permanently.
off-Sets the bit to 0 permanently.
invert-Changes the state to the opposite of the
original transmit or receive state.
