FOCUS System Manual
•Ring all stations on the internal network
simultaneously from any one station on the
internal network or from any extension on
the PBX
•Break in, or interrupt, an ongoing call
involving any of the stations on the
network (for an emergency or a conference
call) either from any of the other stations on
the internal network or from any extension
on the PBX
How it works:
The basic operation of the “internal” portion of the
network is the same as described above. To place
a call from one “internal” station to another or use
the “break-in” or “ring-all” feature from an
“internal” station, just follow the same proce-
dures.
The addition of the PBT module/PBX connection
adds a new level to the network. You assign the
PBT module a three-digit phone number just like
the stations with PBW modules. When calling
from an internal station to a PBX number or vice
versa, you must first call the number of the station
housing the PBT module, as described below.
Just as with internal station-to-station calls, those
between an internal station and the PBX are also
on a “first come, first served” basis. This is
because the station with the PBT module is
basically just another extension on the network. It
has its own three-digit phone number, just like the
other stations. The difference is that it serves as
the common connection between the network and
the PBX. That is, calls in both directions (from the
PBX to the internal network and vice versa) must
first go through the “PBT” station (i.e., the station
housing the PBT module).
When placing a call from the PBX to a network
station (or using the “break-in” or “ring-all”
feature), you must first dial the number for the
PBT station. After getting the network dial tone,
you then dial the number of the station you want
to call (or the “break-in” or “ring-all” code).
The procedure is the same for calling from a
network station to the PBX. First you call the PBT
station. When you get the “PBX” dial tone, dial
the PBX extension you want to call.
To place a call from a station on the network to a
PBX number, lift the handset from the cradle.
When you hear the network dial tone, dial the
three-digit phone number for the PBT station.
After a single ring, you will hear the “PBX” dial
tone. Dial the number for the PBX extension you
want to call. Once you have completed the call,
simply hang up (i.,e., replace the handset in the
cradle) to terminate the connection.
If you hear a busy signal when you first lift the
handset, the (network) line is busy. Hang up and
try again later. If you need to make an emergency
call, use the “break-in” feature described below.
If the PBX number is busy, hang up and try again
later. The “break-in” feature does not work
outside the FOCUS network.
To place a call from a PBX extension to a station
on the network, lift the handset from the cradle.
When you hear the “PBX” dial tone, dial the
phone number for the PBT station. After a single
ring, you will hear the network dial tone. Dial the
three-digit number for the station you want to call.
Once you have completed the call, simply hang up
(i.,e., replace the handset in the cradle) to
terminate the connection. To free the (network)
line for another call, the person at the network
station must also hang up the phone.
If you hear a busy signal after dialing the number
for the PBT station, the (network) line is busy.
Hang up and try again later. If you need to make
an emergency call, use the “break-in” feature
described below.
To break in on an ongoing call on the internal
network from a PBX extension (i.e., when you
dial the number for the PBT you get a busy
signal), dial “#00” (pound zero zero). This
connects you to the stations involved in the call.
This feature is provided for both emergencies and
conference calls. In an emergency, you can
instruct the two stations to hang up and then place
your emergency call. For a conference call, all
three parties can simply stay on the line. Other
stations on the network can join the conference
