The GSM module makes it possible to:
•
automatically make calls to the GSM network and thus significant reduction in
telephone bill of your firm.
•
receive incoming calls and, in connection with the DISA code distribute them to the
branches (analogue internal lines, system lines).
•
When calls are made to the GSM network, to utilise all the services of the PBX
(reconnecting call, conference, rerouting, CLIP-called number display and its
entry on record).
In the current form the module does not make it possible to:
•
convert a fax GSM connection to an analogue fax connected to the PBX,
•
convert a data GSM connection to an analogue modem connected to the PBX.
5.6. Module ISDN S
0
(Order No 1880020)
The module contains two four-wire interfaces BRI or 2B+D (1x ISDN input, 1x
ISDN BUS), and so two calls can pass through it simultaneously. It is intended for
connecting to the public ISDN network and supports connection in the regime PTP
and PTMP.
•
In the regime PTP (Point to Point) the code DDI is supported (i.e., as many
sequential numbers as the user requests of the ISDN provider). It is not possible
to attach any further ISDN equipment to the line. The advantage is the possibility
of merging capacity – when several ISDN modules are fitted they can all have the
same code.
•
In the regime PTMP (Point to MultiPoint) MSN is supported (i.e., upon request it
is possible to allocate up to eight numbers, but it need not be a continuous series
of numbers). It is possible to connect further ISDN equipment to the line (for
example, ISDN card in computer – one number, on the module up to seven
numbers will remain).
We recommend that overvoltage protection be installed to prevent destruction of
the ISDN module by overvoltage.
The control program of the module is stored in a FLASH memory which enables
the updating of the program directly in the PBX.
One of the input RJ45 connectors can be used for simpler creation of an ISDN
bus and thus for the connection of further ISDN equipment (ISDN telephone, fax,
modem).
