Table 5-5. FXO Voice – Slot ss Port p Options (2 of 3)

Signaling Type
Possible Settings: Loop-Start, Loop-Start/Fwd Disc, Ground-Start
Default Setting: Loop-Start
Determines the type of signaling for the FXO voice port.
Signaling Type only appears if:
Port Status is set to Enable.
Operating Mode is not set to DPT.
Loop-Start – Enables the signaling used for basic telephone service stations, simple
PBX trunks, or key systems.
Loop-Start/Fwd Disc – Enables the signaling used for automated answering
equipment.
Ground-Start – Enables the signaling used for two-way PBX trunks. Helps to prevent
“glaring”, i.e., call collision.
Terminating Impedance (ohms)
Possible Settings: 600, 900
Default Setting: 600
Determines the terminating impedance (in ohms) for the port.
Terminating Impedance only appears if Port Status is set to Enable.
600 – The terminating impedance is 600 ohms.
900 – The terminating impedance is 900 ohms.
Wink Delay (10 ms)
Possible Settings: 1 – 99
Default Setting: 15
Determines the amount of delay before the wink signal is generated towards the
network, and when an off-hook signal from the CO is detected in increments of
10 milliseconds.
Wink Delay only appears if:
Port Status is set to Enable.
Operating Mode is set to FXODN/WINK or DPT.
10 to 990 – The valid range is from 10 to 990 ms, in 10 ms increments. The settings are
numbers between 1 and 99, representing such increments. The default is 15, for a wink
delay of 150 ms.
Wink Duration (10 ms)
Possible Settings: 1 – 99
Default Setting: 20
Determines the duration of the wink signal generated towards the network when an
off-hook signal for the CO is detected and after the wink delay has elapsed in
increments of 10 milliseconds.
Wink Duration only appears if:
Port Status is set to Enable.
Operating Mode is set to FXODN/WINK or DPT.
10 to 990 ms – The valid range is from 10 to 990 ms, in 10 ms increments. The settings
are numbers between 1 and 99, representing such increments. The default is 20, for a
wink duration of 200 ms.
