SYSTEM CONFIGURATION
The following illustration shows a
complete switch, with 32 linecards
connecting to the 32 port fabric. As
shown, fiber links are used to inter-
connect the distant (up to 200 feet)
linecards to the fabric.
Alternatively, linecard silicon can
interface directly to the ETT1 devices, if
sufficient board space, power, thermal
regulation, etc., is available.
APPLICATIONS
ATM switches with 32 ports of OC-
192c, or up to 128 ports of OC-48c, or
combinations thereof.
SONET Add/Drop Muxes.
IP switches with 32 ports of 10Gbit/s.
Any combination of the above.
