Combo solutions
Voice lines provided by Alcatel-Lucent ISAM Voice can be delivered from a combo shelf on which voice and DSL are both provisioned. The combo shelf enables simplified cabling with MDF, zero-touch service provisioning and flexible growth of voice or xDSL services.
Shortest-path routing for voice calls
Local voice calls (calls between two subscribers served by the same Alcatel-Lucent ISAM node) are not routed through the NGN backbone, thus decreasing transmission and backbone capacity consumption.
Common shelves with any ISAM application
New Alcatel-Lucent ISAM Voice hardware and software can be installed in existing or new Alcatel-Lucent ISAM standard racks.

Line testing
Metallic Test Access (MTA) is supported for POTS. In- tegrated line testing is also supported in conjunction with the Alcatel-Lucent 5530 Network Analyzer, which facilitates fully integrated narrowband and broadband testing.
Part of the end-to-end IP voice solution
As illustrated in Figure 2 Alcatel-Lucent ISAM Voice is fully integrated with the rest of the Alcatel-Lucent portfolio to offer end-to-end solutions for the NGN/IMS. Layered on top of other Alcatel-Lucent products — intended for the growth of the PSTN network or PSTN legacy migration - ISAM Voice positions the Alcatel- Lucent ISAM family, including the Alcatel-Lucent 1540 Litespan MSAN, as the access/voice gateway
for NGN/IMS deployments. These are focused on the immediate introduction of triple play services. At the same time, the fully standards-based Alcatel-Lucent ISAM Voice supports multivendor triple play NGN/IMS access opportunities.
