Configuring Voice Ports

Release 12.0(7)XK

router(config-voiceport)# condition {tx-a-bit |

tx-b-bit | tx-c-bit | tx-d-bit} {rx-a-bit |

rx-b-bit | rx-c-bit | rx-d-bit} {on | off |

invert}

(For T1/E1 digital voice ports only.) Conﬁgure the voice port to

manipulate the transmit and/or receive bit patterns to match the

bit patterns required by a connected device.

Be careful not to destroy the information content of the bit

pattern. For example, forcing the A-bit on or off will prevent

FXO interfaces from being able to generate both an on-hook and

off-hook state.

Note The show voice port command reports at the protocol

level, while the show controller command reports at the driver

level. The driver is not notiﬁed of any bit manipulation using the

condition command. As a result, the show controller command

output will not account for the bit conditioning.

router(config-voiceport)# timeouts initial

seconds

Specify the number of seconds the system waits for a caller to

dial the ﬁrst digit. The range is 10 to 120. The default is 10.

router(config-voiceport)# timeouts interdigit

seconds

Specify the number of seconds thesystem waits, after a caller has

dialed the initial digit, for the caller to dial each subsequent digit.

The range is 0 to 120. The default is 10.

router(config-voiceport)# timeouts ringing

{

seconds

| infinity}

Specify the maximum number of seconds that a voice port allows

ringing to continue if a call is not answered.

The range is 5 to 60000. The default is 180.

router(config-voiceport)# timeouts wait-release

{

seconds

| infinity}

Specify the maximum number of seconds that a voice port can

remain in the call failure state while the router or concentrator

sends a busy tone, reorder tone, or out-of-service tone to the port.

The value range is 5 to 3600. The default is 30.

router(config-voiceport)# timing digit

milliseconds

If the dial type is DTMF, conﬁgure the DTMF digit signal

duration in milliseconds. The range is 50 to 100. The default is

100.

router(config-voiceport)# timing inter-digit

milliseconds

If the dial type is DTMF, conﬁgure the DTMF inter-digit signal

duration in milliseconds. The range is 50 to 500. The default is

100.

router(config-voiceport)# timing pulse-digit

milliseconds

If the dial type is pulse, conﬁgure the pulse digit signal duration

in milliseconds. The range is 10 to 20. The default is 20.

router(config-voiceport)# timing

pulse-inter-digit

milliseconds

If the dial type is pulse, conﬁgure the pulse inter-digit signal

duration in milliseconds. The range is 100 to 1000. The default is

500.

router(config-voiceport)# timing percentbreak

percent

(FXO only) Specify the percentage of the break period for

dialing pulses. The range is 20 to 80. The default is 50.

router(config-voiceport)# timing guard-out

milliseconds

(FXO only) Specify the duration in milliseconds of the guard-out

period to prevent this port from seizing a remote FXS port before

the remote port detects a disconnect signal. The range is 300 to

3000. The default is 2000.

router(config-voiceport)# impedance {600r | 600c

| 900r | 900c}

(FXO only) Conﬁgure the impedance. The default is 600r (600

ohms real).

router(config-voiceport)# ring number

number

(Analog FXO only) Conﬁgure the number of rings detected

before a call is answered on the FXO port. The range is 1 to 10.

The default is 1.

router(config-voiceport)# ring frequency

number

(FXS only) Specify the local ring frequency (Hertz) for the FXS

voice port. Valid entries are 20 and 30. The default is 20.

Step Command Purpose

1 2 ... 15 16 17 18 19 20 21 22 23 24 25 ... 77 78
