WHAT IS SS-15 BRI (ISDN 2 GSM)?
By interfacing between an ISDN phone exchange and the mobile telephony
network (GSM 900/1800 or 850/1900) cuts down the costs of fixed-to-GSM and
GSM–to-fixed calls.
ISDN 2 GSM was designed to be connected to any ISDN phone exchange so
it meets standard ISDN PBX requirements.
It may be used as GSM interface for an ISDN a phone exchange. Even when
used as standalone unit with an ISDN phone set it can still perform routing of
the calls for minimum costs. Also, by means of a terminal adapter it can be
used with analogue (standard) telephones or with a payphone.
The unit works primarily in voice mode by re-routing incoming or outgoing
calls through the corresponding wireless network. This way there is only cost
of a mobile-to-mobile call inside the same carrier network, instead of the cost
of a fixed-to-mobile call.
The interface enables several types of ISDN connections and may be used for
services such as call forwarding (conditioned or unconditioned), DISA and
voice messages.
When connected to a computer, the SS-15 BRI (ISDN 2 GSM) equipment
may be used to receive and send out SMS’s.
By connecting SS-15 BRI (ISDN 2 GSM) to an ISDN phone exchange, all
local extensions can make calls to GSM networks while keeping down the
costs. Also, when making a call the subscriber is no longer subjected to RF
radiations from the cell-phone. The external antennas can then also be
placed for optimal reception (higher intensity of the radio signal).
Since SS-15 BRI (ISDN 2 GSM) can send billing pulses, a public telephone
(payphone) can also be used by means of terminal adapter.
Finally, ISDN 2 GSM may be used as small ISDN phone exchange by itself,
since it can interconnect up to 8 ISDN local phones and perform automated
routing of calls for minimum cost.
The unit includes the GSM modules, so it does not need supplementary
devices (such as an external GSM phone) to work. Its two SIM cards allow
routing the call through the corresponding GSM operator, for least cost.
