Operating Mode
Possible Settings: FXS, FXSDN, FXSDN/WINK, PLAR, DPO
Default Setting: FXS
Selects the operating mode for the FXS voice port.
Operating Mode only appears if Port Status is set to Enable.
FXS – Enables the Foreign Exchange Station (FXS) mode, supporting a bidirectional
connection to a telephone device, PBX, or key system trunk. This mode uses 4-state
signaling (A&B).
FXSDN – Enables Foreign Exchange Station Software-Defined Network (FXSDN)
mode for operation on software-defined networks. This mode is used by Class 4
switches and uses 2-state signaling (A=B).
FXSDN/WINK – Enables the mode FXSDN with WINK which is similar to FXSDN, but in
addition provides an indication to the central office (CO) when the station equipment is
ready to receive signaling information. This consists of detecting an off-hook signal from
the CO, which initiates a configurable “wink delay” followed by a configurable off-hook
signal back to the CO.
PLAR – Private Line Automatic Ring-down (PLAR) allows “hotline” point-to-point
dedicated connection of two phones. When one phone goes off-hook, the other phone
starts ringing.
DPO – The Dial Pulse Originating (DPO) mode is similar to FXS, except for supporting
out-going, one-way trunks from a PBX (direct outward dialing) or key system, or station
instrument. No ringing is provided in this mode.
