Fle xibility and Survivability for SDH-Based
Netw ork Ser vices
FLX600A is a highly flexible system that can be configured
into a number of possible operating modes. It can serve as a
hub or a digital cross-connect (DXC) system and is ideal for
building advanced ring, linear, and point-to-point networks.
The FLX network can be managed efficiently and cost
effectively using FLEXR

Plus
or FLEXR

management
platforms. This can be done remotely using an X.25 link or
an LCN, or locally using a direct
connection.
Main F eatures
鈥?Flexibility and upgradability (including in-service)
鈥?Modular plug-in unit design
鈥?High survivability against transmission failures (protection
of equipment and traffic at the line, path, and unit levels)
鈥?Digital cross-connect capability allowing flexible traffic
routing
鈥?Quick and easy downloading of software upgrades from
the network management system
鈥?Alarm and performance
reporting to the management
system
鈥?Efficient maintenance
operation using orderwire,
housekeeping, and 64 kbps
user channel
Flexib le Configurations
Multiplexer
: aggregates STM 4/16,
2/34/(45)/140 Mbps tributaries,
and STM-1/4
Hubbing (HUB): ideal as a
central node
Add/Drop (ADM): ideal for linear
networks (L-ADM) and ring networks (R-ADM)
Terminal (TRM): ideal for point-to-point networks
DXC systems:
cross connects any pair of signals transferred
over STM-1/4/16 lines at any VC level and is ideal for a
simple meshed network and for an inter-ring application.
