ULC-1000AN MSAN: The solution to NGN migration
With the leading-edge MGU (Media Gateway Unit) module, the ULC-1000AN acts as a VoIP media gateway designed for commercial VoIP deployment. It provides superior voice technology for connecting legacy telephones (POTS), fax machines and PBX systems over IP-based telephony networks.
ULC-1000AN in NGN architecture
The ULC-1000AN complies with H.248 (Megaco), MGCP and SIP protocols. IP-based voice services are carried across the packet core network and when they reach edge network, the ULC-1000AN media gateway takes over the service delivery to customers using the existing narrow band voice technology (POTS)
No change is perceived by customers, because they are able to continue using existing user telephones or terminals.
Using standard G.711, G.729A, G.726 and G.723.1 compression algorithms with Voice Activity Detection (VAD) and silence suppression, the ULC-1000AN provides efficient bandwidth optimization, leaving more bandwidth for data transportation. The ULC-1000AN was designed and tested to be fully interoperable with leading soft switches.
Migration
The ULC-1000AN is capable of having V5.2-interfaces coexisted with VoIP media gateway function in the same platform. It is ideal for gradual migration from conventional to NGN telephony.
