• Shutdown and no shutdown are required on the voice port after loop-length is configured for it totake
effect.
• Because up to 2 ren is supported on long-loop (OPX-lite) FXS, when loop-length long is configured on
the FXS voice port, if its existing ren configuration is greater than 2, it will be changed automatically to
2, a message “The existing ren configuration is changed to 2" is displayed on the console.
• When loop-length short is configured on the FXS voice port, if the voice port has ring dc-offset configured,
the ring dc-offset configuration will be removed. A message “The existing ring dc-offset configuration
is removed” is displayed on the console.
ren
The existing ren CLI under FXS voice port will accept value 1-2 for FXS voice port with loop-length long
configured. For short loop-length analog FXS voice port, ren CLI will accept value 1-5.
ren dc-offset
The existing ring dc-offset CLI is configurable on the long loop-length FXS voice port.
cm-current-enhance
The existing cm-current-enhance CLI is configurable on the long loop-length FXS voice port.
vmwi
The existing vmwi [fsk | dc-voltage] is configurable on all on-board FXS voice ports.

Cisco IOS Bulk Configuration
An optional bulk-configuration mechanism for voice-port and voice dial peer is available to save on time.
group
The group option is added to dial-peer CLI for dial peer bulk configuration. It has the following formats:
dial-peer group <tag> pots
dial-peer group <tag> pots all stcapp
The second command from the above list will create dial peers on all analog voice ports as stcapp ports by
expanding it to the following three commands:
dial-peer group <tag> pots
service stcapp
port all
The group command is specific for stcapp-controlled analog ports. Therefore, only a subset of dial peer
commands are supported, which are as follows:
1. port
