KT Tests Lucent's Universal Gateway for Circuit-to-Packet Migration

KT (formerly Korea Telecom) is testing Lucent Technologies’ APX 8000 Universal Gateway system as a means of migrating traffic from circuit networks to an IP-based network. Lucent’s APX 8000 Universal Gateway will be deployed at KT’s Research Center in Daeduk by the end of July. The equipment will act as a trunk access media gateway accepting dial, VoIP and fax-over-IP traffic and then interfacing with KT’s softswitch. Lucent’s multi-protocol system supports H.248, IPDC, SIP, H.323, V.92, and Personal Handyphone System (PHS) protocols. It achieves toll quality voice that meets G.711, G.729, G.728, G.723.1 standards. Lucent supplied its AnyMedia Line Access Gateway for KT’s access network build-out last October. In addition, Lucent has previously supplied KT with traditional voice switching systems, such as the 4ESS Toll Switch and 5ESS Switch, as well as optical transport and crossconnect gear since the 1980s.
