SC-5001-4E1 Trunk gateway series with 4 port E1/T1

SC-5001 E1/T1 trunk gateway series is a multi-functional trunk gateway designed for large enterprises, telecom operators, call centers and providers of value-added services. It supports a range of signaling protocols, realizing the interconversion between SIP/H.323 and traditional signals such as SS7 and PRI. It supports multiple codec methods G.711, G.723, G.729 and ILBC, improves the utilizing efficiency of trucking resources while ensuring voice quality.

SC-5001 E1/T1 trunk gateway series is with high-efficient design and strong DSP processor to ensure the inter-conversion of PCM voice signal and IP packets, although the gateway has been fully loaded. It can be connected with multiple devices such as softs witches, PBX and those servers equipped with digital trunk interfaces.
