Routers in the 3Com

®

 Router 3000 Family provides the following types of ports:

■

Ethernet port

■

Synchronous/asynchronous serial port

■

Auxiliary (AUX) port

■

ISDN BRI S/T and U port

■

CT1/PRI port

■

E1/CE1/PRI port

These features allow you to combine the various networking technologies, such as 
PSTN/ISDN, FR (Frame Relay), X.25, leased line, and T1 line. These multiple ports 
also allow Router 3000 series routers to interoperate with the products of other 
manufacturers. 

Router 3000 routers use three types of memory:

■

Synchronous Dynamic Random Access Memory (SDRAM) — Saves router 
operation system software

■

Flash memory — Saves router program files, configuration files and so on 

■

Boot ROM — Saves the boot and initialization programs of the router
