Standalone router racks, called Router
Cores, that have no DSP and no control
surface attached, can be used to increase
the capacity of I/O connections by
providing an extra 16 or 32 router ports
with each additional rack.
Router Cores can be used as a central
point for shared I/O resources and
console router connections. Dedicating a
standalone router as the Master Router in
a network and locating it in an equipment
room, powered on 24/7, ensures that
the network is always active and that any
console that is powered on has access
to all their own I/O as well as all I/O
connected to the Router Core.
