Table 2-1. Comparison of cross-connect and line-switch modes of operation
Mode→
Characteristics
↓
Cross-Connect Mode Line Switch Mode
Path Programmability All individual DS0s are mapped
independently
Routes from r
eceiver to transmitter are
select
ed for complete DS1 stream, no
DS0s are broken out.
Immunity to DS1 path
disturbances
More stable; small incoming
disturbances may be absorbed by
Cross-Connect mode DACS
module.
Less stable; m
oderate incoming
disturbances may
affect outgoing DS1
streams of Line-Switch m
ode DACS
module.
Map / Route Switching
Behavior
Usually cleaner switch, less
disturbances in the network.
Switch may cause small disturbances to
propagate through other Line Switches in
the network.
Through-Delay Short (hundreds of microseconds per
each pass through the DACS
module).
Very short (te
ns of microseconds per each
pass through
the DACS module).
