Voice Port Testing Commands
These commands allow you to force voice ports into specific states for testing. They require the use of
Cisco IOS Release 12.0(7)XK or 12.1(2)T or a later release, and they apply only to Cisco 2600 and 3600
series routers, and to Cisco MC3810 multiservice concentrators. The following types of voice-port tests
are covered:
• Detector-Related Function Tests, page 110
• Loopback Function Tests, page 112
• Tone Injection Tests, page 113
• Relay-Related Function Tests, page 114
• Fax/Voice Mode Tests, page 114
Detector-Related Function Tests
Using the test voice port detector command, you are able to force a particular detector into an on or off
state, perform tests on the detector, and then return the detector to its original state.
To configure this feature, use the following commands in privileged EXEC mode:
Command Purpose
Step 1
Cisco 2600 and 3600 Series Routers Analog Voice Ports
Router# test voice port slot/subunit/port detector
{m-lead | battery-reversal | loop-current | ring |
tip-ground | ring-ground | ring-trip} {on | off}
Cisco 2600 and 3600 Series Routers Digital Voice Ports
Router# test voice port slot/port:ds0-group detector
{m-lead | battery-reversal | loop-current | ring |
tip-ground | ring-ground | ring-trip} {on | off}
Cisco MC3810 Multiservice Concentrators Analog Voice Ports
Router# test voice port slot/port detector {m-lead |
battery-reversal | loop-current | ring | tip-ground |
ring-ground | ring-trip} {on | off}
Identifies the voice port you want to test. Enter a
keyword for the detector under test and specify
whether to force it to the on or off state.
Note For each signaling type (E&M, FXO,
FXS), only the applicable keywords are
displayed. The disable keyword is
displayed only when a detector is in the
forced state.
