EID3000 E1/T1 digital gateway is the bridge between the public switched telephone network (PSTN/PLMN) and IP network, realize signaling transform from R2,ISDN/PRI, SS7, QSIG signaling to H.323, SIP and MGCP as well as PSTN bear channel and IP network media stream convert.

Aliwei EIA3000 modularization trunk gateway 1U including 2 slots can set 1 E1/T1 trunk modules, provide up to 8E1/T1 trunk interface and 2U including 6 slots can set 1E1/T1 trunk modules, provide up to 24E1/T1 trunk interface Provide high density VoIP communication and dispose capability. EID3000 can service for traditional carriers, second class carriers, big enterprises and voip virtual carriers.
