1. What is MobiLink GSM?
It is an interface for your profit! By interfacing between a
phone exchange and the GSM 900/1800 mobile telephony
network it cuts down the costs of fixed-to-GSM and GSM–to-
fixed calls.
MobiLink achieves a direct link between a trunk of the
phone central and the GSM 900/1800 mobile network. By
using the PBX facility of automatically routing the calls
depending upon prefix, any call from an extension to a
mobile phone in the GSM network will get out through the
trunk on which MobiLink was installed. This way you will pay
just the cost of a mobile-to-mobile call inside the same
network, instead of the cost of fixed-to-mobile call.
Also, for any call issued from a GSM phone towards the
number of the MobiLink unit connected to the PBX, you may
call any local subscriber you want, still paying only the cost of
a mobile-to-mobile call inside the GSM network instead of
being billed for a mobile-to-fixed call.

MobiLink while the other end of the cable must be connected
to a trunk of the PBX. If the phone exchange does not have a
RJ11 connector available, you may connect directly to the two
wires coming from the PBX.

phone cable shipped in the MobiLink package are fitted with
male RJ11 connectors.

connector of MobiLink. The other end (with DB9) must be
inserted into the COM port of the PC used for configuration.

connector and then plug the adapter into the receptacle of the
230V ac mains outlet.
