E&M
Router(config-voiceport)# signal {wink-start |
immediate-start | delay-dial}
The keywords are as follows:
• wink-start—(default) Indicates that the
calling side seizes the line, then waits for a
short off-hook wink from the called side
before proceeding.
• immediate-start—Indicates that the calling
side seizes the line and immediately proceeds;
used for E&M tie trunk interfaces.
• delay-dial—Indicates that the calling side
seizes the line and waits, then checks to
determine whether the called side is on-hook
before proceeding; if not, it waits until the
called side is on-hook before sending digits.
Used for E&M tie trunk interfaces.
Note Configuring the signal keyword for one
voice port on a Cisco 2600 or 3600 series
router VIC changes the signal value for
both ports on the VIC.
Step 3
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.
Step 4
Router(config-voiceport)# dial-type {dtmf | pulse}
(FXO only) Specifies the dialing method for
outgoing calls.
Step 5
Router(config-voiceport)# operation {2-wire | 4-wire}
(E&M only) Specifies the number of wires used
for voice transmission at this interface (the audio
path only, not the signaling path).
The default is 2-wire.
Step 6
Router(config-voiceport)# type {1 | 2 | 3 | 5}
(E&M only) Specifies the type of E&M interface
to which this voice port is connecting. See Table 5
on page 40 for an explanation of E&M types.
The default is 1.
Step 7
Cisco 1750 Router and 2600 and 3600 Series Routers
Router(config-voiceport)# ring frequency {25 | 50}
Cisco MC3810 Multiservice Concentrator
Router(config-voiceport)# ring frequency {20 | 30}
(FXS only) Selects the ring frequency, in hertz,
used on the FXS interface. This number must
match the connected telephony equipment and
may be country-dependent. If not set properly, the
attached telephony device may not ring or it may
buzz.
The keyword default is 25 on the Cisco 1750
router, 2600 and 3600 series routers; and 20 on the
Cisco MC3810 multiservice concentrator.
