type
The signaling method selection for
type
depends on the connection that you are
making. The E&M interface allows connection for PBX trunk lines (tie lines) and
telephone equipment. The FXS interface allows connection of basic telephone
equipment and PBXs. The FXO interface is for connecting the central office
(CO) to a standard PBX interface where permitted by local regulations; it is often
used for off-premises extensions.
The following options are available on T1 and E1 controllers:
•
e&m-immediate-start—
no specific off-hook and on-hook signaling
•
e&m-delay-dial—
the originating endpoint sends an off-hook signal and
then waits for an off-hook signal followed by an on-hook signal from the
destination
•
e&m-wink-start—
the originating endpoint sends an off-hook signal and
waits for a wink signal from the destination
•
fxs-ground-start—
Foreign Exchange Station ground-start signaling
support
•
fxs-loop-start —
Foreign Exchange Station loop-start signaling support
•
fxo-ground-start—
Foreign Exchange Office ground-start signaling support
•
fxo-loop-start—
