To configure basic analog voice port parameters on Cisco 2600 series, Cisco 3640 and Cisco 3660 routers, use the following commands beginning in global configuration mode:

Command

Purpose

 

 

Router(config)# voice-portslot/subunit/port

Enters voice-port configuration mode.

 

The arguments are as follows:

 

slot—Specifies the number of the router slot

 

where the voice network module is installed.

 

port—Indicates the voice port. See Table 1 on

 

page 2 for valid entries.

 

subunit—Specifies the location of the

 

Cisco High-Density Analog Voice/Fax Netwo

 

rk Module (NM-HDA). The valid entry is 0.

 

Note A slash must be entered between

 

arguments.

 

Valid entries vary by router platform; enter the

 

show voice port summary command for

 

available values.

 

 

FXO or FXS

Selects the access signaling type to match that of

Router(config-voiceport)# signal {loop-start

the telephony connection you are making. The

ground-start}

keywords are as follows:

 

loop-start—(default) Uses a closed circuit to

 

indicate off-hook status; used for residential

 

loops.

 

ground-start—Uses ground and current

 

detectors; preferred for PBXs and trunks.

 

 

Router(config-voiceport)# cptone locale

Selects the two-letter locale for the voice call

 

progress tones and other locale-specific parameters

 

to be used on this voice port.

 

Cisco routers comply with the ISO 3166 locale

 

name standards. To see valid choices, enter a

 

question mark (?) following the cptone command.

 

The default is us.
