Configuring the Voice Port
This section discuss the changes and modifications on the following commands:
loop-length
The loop-length CLI is created to configure the analog FXS voice port. It has the following format:
voice-port x/y/z
[no] loop-length [long | short]
The loop-length CLI has the following characteristics:
• For the Cisco VG400 platform, the default is short loop-length. This command is not applicable to analog
FXS on motherboard slot.
• This command is applicable to all 48 FXS voice ports on SM-D-48FXS-E and the first 4 (0-3) FXS voice
ports on SM-D-72FX like the Cisco VG400 platform.
• The default FXS is short loop-length and long loop-length FXS needs to be configured.
• The first eight voice ports 0/0/0-7 can be configured as long loop (OPX-lite).
• FXS voice ports on VIC 1 (0/1/0 - 0/1/23) will not support long loop. By default, they are short-loop
FXS.
