ATM transport networks and their inherent quality of
service play an important role in today’s multi-service networks. As
networks continue to converge and traffic migrates from cell to packet,
the monitoring of ATM backbones used in conjunction with IP and TDM
infrastructure presents a unique set of challenges. Features like
circuit emulation and Inverse Multiplexing over ATM (IMA) make
monitoring expensive and, in some cases, impossible since ATM support
is often not available in next generation monitoring solutions. OptiCop
Converger’s ability to terminate and convert ATM cell traffic combined
with its advanced Hybrid Inspection Technology (HIT) provide a means to
extract the traffic of interest and leverage existing investments in
test and monitoring tools.
The A-Series OptiCop Converger systems can be configured
to meet the most demanding applications, with the ability to monitor
SONET/SDH and PDH ATM circuits ranging from T1/E1 to OC3/STM-1 through
OC12/STM-4. Inverse multiplexing is also supported on either 256
discrete T1/E1 interfaces or on up to 512 T1/E1 circuits embedded
within SONET/SDH pipes. With up to 24 SONET/SDH network/tool
interfaces, the A-Series OptiCop Converger can monitor multiple
broadband circuits in either half or full duplex scenarios and will
operate in conjunction with Automatic Protection Switching, ensuring
monitoring applications always have the access they need.
The A-Series OptiCop Converger is available in two
models, the A-1200 and the A-2400, supporting 12 and 24 optical/copper
interfaces respectively. Optional support for up to 256 discrete T1/E1
interfaces is offered on the A-1200. Both models are available with
either a fixed relationship between network inputs and tool outputs or
with optional traffic routing, where the input to output relationship
becomes a user defined logical path. The table below illustrates
example port configurations available. (Note: In certain input to
output aggregation configurations, traffic inspection and filtering are
required to prevent oversubscription)
