impedance [600c | 600r | 900c | 900r]
Configures the AC impedance of the FXS or FXO interface. Use
the no form of this command to return to the default value of 600c.
600c
Specifies an impedance of 600
Ω + 2.16 µF
600r*
Specifies an impedance of 600
Ω
900c
Specifies an impedance of 900
Ω + 2.16 µF
900r
Specifies an impedance of 900
Ω
loopback [analog |digital]
Activates a loopback on the FXS or FXO Module. Use the no form
of this command to deactivate the loopback.
analog
Initiates a loop back toward the T1 network side
of the connection after passing through analog
filters in the voice codec
digital
Initiates the same loopback before passing
through analog filters in the voice codec.
rx-gain [-12.0 to 6.0] (configure in 0.1 dB increments)
Defines the receive gain characteristics on the FXS or FXO
interface. Receive gain determines the amplification of the
received signal before transmitting out the FXS or FXO interface,
By default, the rx-gain is -3.0 dB.
signal [loop-start | ground-start]
Configures the signaling mode for the FXS interface. The default is
loop-start.
loop-start
Bridges the tip and ring to indicate an off-hook
(seizing the ling) condition.
ground-start
Applies resistance to the tip conductor of the
circuit to indicate an off-hook condition.
* Indicates default values
test [loop | ring-ground | tone]
Provides manual control of the FXS or FXO interfaces for testing.
Use the no form of this command to deactivate the test.
loop
Enables a 2-wire “hook switch” on the FXS or
FXO interface that controls the DC current flow.
