nents provide PSTN-quality VoIP,

vice ISAM access solution by enabling

PSTN voice in an
NGN/IMS access scenario
In cases where customers decide
to migrate via a two-step approach,
Alcatel-Lucent ISAM Voice enables
the migration from NGN to the IMS
core with a simple software upgrade.
Carrier-grade voice
Alcatel-Lucent ISAM Voice leverages
comprehensive redundancy concepts
such as server/network card redun-
dancy, duplicate power distribution
to the line cards, multiple fans and
clock redundancy. On top of this,
failover mechanisms are available when
connecting to an IMS/NGN network
and lawful intercept is also supported.
A non-blocking architecture
The Alcatel-Lucent ISAM family
delivers superior-quality VoIP services
due to its treatment of packetized voice
traffic. It applies strict priority schedu-
ling, assuring minimum delay and
premium VoIP quality. Moreover,
scalability is ensured because user
agents are distributed to the linecards.
