MTG600 series is a kind of digital trunking gateway based on embedded operating system. It supports standard SIP/H.323 protocol, with large-capacity carrier class telephone trunking gateway functions. Currently it supports 1/2  E1/T1 interfaces and can realize intercommunication with mainstream manufacturers softswitch system, and interwork  with carrier's local Telephone exchange by PRI/SS7 interface.

• Protocol interface: standard SIP 1.0/2.0;H.323 V4 protocol; PRI network side/user side; SS7 TUP/ISUP protocol.
• Voice codec: standard G.711A/U,G.723,G.729AB.iLibc, supporting voice quality guaranteeing technologies such as VAD(Voice Activity Detection), CNG (ComfortNoise Generation), JitterBuffer and EC,  reducing time delay and distortion.
• Hardware interface: two FE0/FE1 interfaces connecting to L3/L2 exchange of IP metropolitan area network (MAN), also called business interface or network management interface; several E1/T1 interfaces (support 1/2 E1/T1 interfaces).
• High compatibility: capable of intercommunicating with different manufacturers softswitch system.
• Carrier-class access equipment: multi-routecontrol,interval control, call forbid, call numberlimit, number replacement.
• Security guarantee: as an embedded system it is reliable and stable, won't be disturbed by any virus and provides a good certification mechanism to protect user's interests.
• Hot standby: double power supplies ensure thesystem runs normally & reliably.
