E1 GSM Gateway / E1 Channel Banks / GSM Multiplexers digitally integrate the wireless GSM interfaces and the E1 interface. E1 GSM Gateway may be used for terminating in-bound and out-bound long distance VoIP, VoATM, or DCME E1 traffic directly into the GSM wireless networks (instead of the analog PSTN lines). The interface of the network side is E1 digital interface. The interface on the wireless side is 30 x GSM wireless links. Our equipment replaces the cumbersome fixed wireless terminals and provides accurate answer supervision and line disconnect supervision, plus a host of other advantages, which include fast connection times (very short PDD) and high ASR rates that compete with the industry's best.
