of cause. The update is free of charge: Only the cost for the necessary
telephone connection is charged to you. After finishing the update you
will be called to be informed about success/failure.
If the procedure was shorter than 60 seconds, but you hear
the acknowledgement tone, your PBX firmware was already
up to date.
If you receive this information call and are listening to a busy tone
instead of the acknowledgement tone, the update was unsuccessful. In
this case, repeat the whole procedure.
If you listen to a busy tone instead of the acknowledgement tone after
dialling
06#, the server port is busy. Put the receiver on-hook and try
again later.
You should better start the update in a non busy situation (e.g. after
hours), because all calls are automatically disconnected by the PBX.
After a successful PBX software update existing LCR data may be de-
leted.
The version number of the software used in this PBX can be requested
via system telephone (COMfortel 1500/2500 and COMfort 1000/1200/
2000 plus), a connected system display SD-420 (special accessory) or
via any internal telephone, as described here.
The version number is compounded by two digits and one letter (e. g.
1.2b) and is formatted to 4 digits for output to the phone:
˾ 1st digit: before the comma;
˾ 2nd digit: after the comma;
˾ 3rd and 4th digit: letter, e.g. a=01, b=02,..., z=26)
Connecting analog Devices
If you like to connect an additional device or to connect another device
to a connection box e.g. a telephone instead of a fax machine, please
contact your specialized dealer or the supervisor of your PBX. If you like
to connect other telephones to the already existing and configured ana-
log connections (e.g. replace a pulse dial telephone by a new DTMF tel-
ephone), please pay attention to the following: The analog subscriber
connections enable the connection of most of the analog units with
pulse dialling or dual-tone multi-frequency dialling (telephone, fax
machine, modem, answering machine). Units with a DTMF dialling must
have a FLASH key (so-called signal key R).
The connection plugs of telephones or Fax/TAM machines are put into
the jacks marked with „F“, the plugs of all other devices are put into the
jack marked with „N“.
If you pick up the receiver telephone after having plugged in a new tel-
ephone, please dial
7 and hang up. Thanks to this the PBX will learn
the dialling mode.
If the new telephone has a dual-tone multi-frequency dialling, check
whether the FLASH key was set and set the FLASH period as short as
possible (see operation instruction of the telephone). Then you execute
the programming described in the following. Subsequent to this the PBX
has learned the exact duration of the FLASH time of your telephone.
This is very important e.g. for the transfer or Query. Analog telephones
that execute certain function via T-Net function key/menu are using a
long FLASH (300 ms). Often an additional FLASH key is available. Con-
figure this also to 300 ms and execute the following programming again.
Connecting ISDN Devices
If you like to connect an additional device, please contact your special-
ized dealer or the supervisor of your PBX. If an S
0
bus is connected to
the internal S
0
port, there are often more connecting boxes than units
but you will need a new internal telephone number for the new device.
This must be configured with the configuration program COMset.
Besides this the quantity of the units that can be operated on one S0
port is limited. You are able to connect up to eight ISDN devices, a max-
imum of four of them without their own voltage supply (that applies to
most of the ISDN telephones). If you like to replace one device by an-
other (e.g. telephone by telephone or ISDN PC-controller by ISDN PC-
controller), you will also have to pay attention to the fact that a maximum
of four devices per S0 port may get their voltage supply out of the PBX.
All the devices should be certified Euro-ISDN units in order to guarantee
a proper functionality.
The connecting cable of an ISDN device may
have a maximum length of 10 m. It is
equipped with a Western plug that you plug
into the ISDN wall jack as shown in Pic. 7. (If
you like to unplug the Western plug out of the
wall jack again, you will have to press the
lever in order to remove it). In case of self
powered ISDN devices you have to connect
the power supply with the 230 Volt mains.
Then you must enter the MSN into the new unit (see instruction manual
of the telephone). This MSN must match with an MSN configured with
COMset for the internal S
0
port.
