Setting Up5-279161-A2-GH30-30 April 1998Table 5-5. FXO Voice – Slot ss Port p Options (2 of 3)Signaling TypePossible Settings: Loop-Start, Loop-Start/Fwd Disc, Ground-StartDefault Setting: Loop-StartDetermines 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, simplePBX trunks, or key systems.Loop-Start/Fwd Disc – Enables the signaling used for automated answeringequipment.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, 900Default Setting: 600Determines 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 – 99Default Setting: 15Determines the amount of delay before the wink signal is generated towards thenetwork, and when an off-hook signal from the CO is detected in increments of10 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 arenumbers between 1 and 99, representing such increments. The default is 15, for a winkdelay of 150 ms.Wink Duration (10 ms)Possible Settings: 1 – 99Default Setting: 20Determines the duration of the wink signal generated towards the network when anoff-hook signal for the CO is detected and after the wink delay has elapsed inincrements 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 settingsare numbers between 1 and 99, representing such increments. The default is 20, for awink duration of 200 ms.
