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. ISaM Voice components
As illustrated in Figure 1, the main hardware components
of Alcatel-Lucent ISAM Voice are:
• an integrated voice packet server (NVPS) for H.248
signaling that interfaces with the NGN/IMS network
through an H.248/Megaco signaling interface. In the
case of SIP signaling, the user agent is hosted on the
line termination card.
• Line termination (LT) boards to interconnect with POTS
lines, ISDN lines (basic access line terminations, BRA)
• Splitter cards
