Command History

Usage Guidelines

This command is supported only on the Cisco MC3810, and only if an installed BRI voice module

(BVM) is equipped to supply line power (phantom power).

This command is used only on a BRI port operating in NT mode. A BRI port operating in TE mode

is automatically disabled as a source of line power, and the line-power command is rejected.

When you enter the line-power command, the line power provision is activated on a BRI port if the

port is equipped with the hardware to supply line power. When you enter no line-power, the line

power provision is deactivated on a BRI port.

Note If the BRI port is operating in NT mode, the line-power command will be accepted, but will

have no effect if a BVM is not equipped to supply line power.

Example

The following example conﬁgures a BRI port to supply power to an attached TE device (only if the

BVM is equipped to supply line power):
