This paper discusses the architectural complexities of extending Lucent's 5
ESS(R)-2000 Digital Switch using the 7R/E(TM) Packet Driver to add voice te
lephony over ATM (VTOA) with switched virtual circuits (SVCs). While meetin
g customers' tight deadlines for introducing this technology, this project
addressed many of today's most complex issues, including platform migration
, circuit-to-packet switch conversion, and voice/data migration. To provide
the media gateway function, the PacketStar(TM) Access Concentrator (develo
ped at Yurie Systems, now part of Lucent Technologies) was incorporated int
o Lucent's long-standing, premier switching product, the 5ESS-2000 Switch.
Additional forward-looking technology from lucent provided the connection/s
ignaling gateway functionality.
