1INTRODUCING THE ROUTER 3000 DSL

FAMILY

Introduction The 3Com Router 3000 DSL Family products are oriented for SOHO (small

office/home office) subscribers.

The 3000 DSL Family provides ADSL ports, G.SHDSL ports and/or ISDN ports. With

one or two subscriber lines, subscribers can be connected to CO (Central Office)

for broadband Internet access. The ISDN port is often used as backup port, but it

can also serve as an uplink port when the ADSL or G.SHDSL port fails. In

downstream direction, they provide four 10/100BASE-T Ethernet ports. Data

switching between them is Layer 2 (L2) switching, which supports port isolating.

With the ports compliant with the international standards. The Router 3000 DSL

Family products can interoperate with the products of other manufacturers on all

levels.
