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.
