MODE (FXS)
FXS supervision mode. The Mode setting should be determined by the type of equipment to
which you are connecting to the port. All options use two-wire balanced connections. Possible
values are:
• FXS (default): Foreign exchange subscriber. This
option enables you to connect the
system to a two-way (both inbound and outbound calls) PBX trunk or a key system trunk.
The system requires a ringing generator for this option.
• FXSDN: Foreign exchange subscriber-defined network. This option provides access to
new services offered by advanced networks from many major carriers. The system
requires a ringing generator for this option.
• FXSDNWINK: Foreign exchange subscriber-defined network wink start operation. This
option uses the same type of signaling as FXSDN and provides a 150-millisecond delay,
then a 200-millisecond “wink” back to the central office when the FXS port sees an
off-hook condition from the central office. The system requires a ringing generator for
this option.
• TR08: Frame format signaling and data link as defined in
TR-TSY-000008 Mode 1 for
circuits using AT&T Subscriber Loop Carriers (SLC-96) facilities. This option connects
the port to one-way outgoing trunks from a PBX, CENTREX, key system, or telephone
set to an SLC channel. The SLC96 mode also must be active on the associated WAN
interface.
