If you are connecting a station device such as an analog
telephone, a fax machine, or a Key Telephone System
(KTS) to the Voice/Fax connector on the back of the unit,
FXS (Loop Start) will likely be the correct Interface option
most of the time.
If the station device uses ground start, then choose the
FXS (Ground Start) option. Refer to the device’s user

If you are using an extension from your PBX, then choose
the FXO option. Check with your in-house telephone

connection is 2-wire or 4-wire. If Wink signaling is used,
then the Wink Timer is enabled with a default of 250

personnel for this timer setting. If the Pass Through
check box is selected, a continuously open E&M voice
path is established between two channels to pass voice

systems.

Options Regeneration group is enabled. Check with your
in-house telephone personnel to verify whether your local
PBX dial signaling is Pulse or DTMF (tone). Set the
Regeneration option accordingly. In the Max Dial Digits
box, enter the maximum number of digits allowed when
dialing a phone number. The default setting is 5. In the
Inter Digit Time box, enter the maximum amount of time
