Alcatel-Lucent OMSN Product Family 10
Reliable, carrier-class
product family
Their resiliency features also make the Alcatel-Lucent
OMSN products ideal for a multiservice transport-node
solution. In terms of hardware, maximum reliability is
achieved by a 1 + 1 hot standby protection mechanism
for all common parts and electrical tributary ports. Matrix,
control and synchronization functions are duplicated.
Power-supply protection is inherent, because the DC/DC
conversion function is distributed on each card.
For traffic protection, single and dual-ended linear
multiplex section protection (MSP) and Subnetwork
Connection Protocol (SNCP) protection, with the drop-
and-continue function, are provided for improved traffic
availability. The Alcatel-Lucent 1660 SM and Alcatel-
Lucent 1662 SMC also support up to 2 x 2 fiber STM-64
or STM-16 multiplex section-shared protection rings
(MSPRINGs) respectively. Collapsed single- and dual-
node interconnections support cost-effective closure and
interconnection of multiple rings.
The Alcatel-Lucent OMSN family consolidates the
extensive experience gathered by Alcatel-Lucent in
optical networks through hundreds of thousands of
installations worldwide.
