Alcate-Lucent ISAM Voice 5
With the Alcatel-Lucent ISAM family, you can also support
video penetration in flexible deep-fiber scenarios. This en-
ables the optimum reuse of the copper plant and improved
subscriber high-capacity reach. With ISAM Voice, the
Alcatel-Lucent ISAM family also supports the deploy-
ment of legacy PSTN interfaces and NGN/IMS media
gateway functionality over the same platform in order to
facilitate network convergence without discontinuity in
subscriber offerings.
