Alcate-Lucent ISAM Voice4
IP Voice Transformation with Alcatel-Lucent ISAM Voice
Bundling opportunities with Alcatel-Lucent
ISAM during IP voice migration
PSTN transformation is driven by fierce competition,
erosion of voice revenue, network obsolescence, IP network
transformation, bringing fiber closer to the end user, and
the desire to introduce new and compelling voice-related
services. As a result, you need a flexible solution to act on
these challenges.
The Alcatel-Lucent IP-based ISAM — a major component
of both the Alcatel-Lucent Triple Play Service Delivery
Architecture (TPSDA) and the Alcatel-Lucent end-to-
end IP Voice solution — is ideally positioned for PSTN
network transformation.
Migrating legacy voice lines
For primary line migration, the Alcatel-Lucent ISAM
family provides a network-based voice solution that lets you
choose either SIP or H.248 as the signaling protocol. With
this network-based solution, packetization occurs in the
access node, so you don’t need to change end-user equipment
and the life-line support model (unlike the CPE-based
approach — the alternative method for voice access).
What’s more, the Alcatel-Lucent ISAM family offers superb
VoIP quality of service (QoS). With advanced queue man-
agement for voice delivery, strict priority over any other
service, you can rest assured of minimum transfer delay.
Together with the support of both SIP and H.248, this
advanced QoS implementation for voice, provides the
most flexible path to IP voice transformation.
Delivering voice and data convergence
with broadband evolution
As you expand your broadband rollout to increase coverage
of IPTV while offering high-speed Internet access, you
can lower the cost of modernizing the PSTN. Your invest-
ment in a true Triple Play Service Delivery Architecture
(TPSDA) meets not only the challenge of obsolescence,
but also lowers operational expenses (OPEX) via unified
training and network management, as well as through
shared spares and software upgrades for voice and broad-
band services. In addition, your OPEX is lowered through
simpler bundled service offerings with self-profiling options
for your customers.
