SX5e GSM PBX FWT
The SX5e GSM PBX FWT allows for enterprise On-Premise Equipment or PBX operation when
the SX5e is connected to the trunk or extension side of a PBX.
Trunk Side PBX Connection (Trunk Mode)
When the SX5e is connected to the trunk side of a PBX, it allows users within the enterprise to
take advantage of potentially lower cellular/PCS rates by routing outgoing calls to the GSM
network. Incoming calls to the SX5e from outside the enterprise can be routed to the PBX.
Depending on the PBX setup, these incoming calls could also be routed to a specific extension.
Trunk Side Setup (Trunk Mode)
To use the SX5e Trunk Mode, con-
nect an analog trunk from the PBX
into the trunk connector
of the SX5e (marked with telephone
icon) - see Figure 14.
HINT: If the SX5e has been changed
to Extension Mode, be sure to change
it back to Trunk Mode. To do this,
connect a tone-dial (DTMF) telephone
to the trunk side jack on the SX5e
and press: #
*
108
*
2 #.
Extension Side PBX Connection (Extension Mode)
When the SX5e is connected to the extension side of a PBX, it allows users to call into the
enterprise via the SX5e, dial an extension, be routed to an extension automatically, or connect
back out to the PBX trunk.
Extension Side Setup
To use the SX5e in Extension Mode, connect
an analog extension from the PBX to the
extension connector of the SX5 (RJ-11 with
no markings) - see Figure 15. Then connect
a DTMF phone to the trunk side (RJ-11
marked with a telephone icon) and set the
SX5e to Extension Mode by pressing: #
*
108
*
1 # on the DTMF phone. The SX5e
is now in Extension Mode.

PBX must only be connected to the extension side of the SX5e (unmarked) -
see Figure 15. Improper connections could damage the SX5e.
