ADC 300S Specifications

Megabit Modem 300S

High-Performance SDSL Modem

The Megabit Modem® 300S is a high­performance SDSL modem that connects
individual power users or small LAN
environments to a frames-over-SDSL service.
The 300S may be used “back to back” with
another 300S for simple LAN extension
applications, or it may be used with the
MM6000 shelf to concentrate 10 MM300S
units in the central location for higher density
applications.

ADC’s rate-selectable modems enable the user
to manually choose transmission speed in
order to obtain the best possible data rate for
distance and line condition. Typically,
subscribers close to the provider’s point of
presence will receive the highest data rate
available, while subscribers far away will still be
reachable at lower rates.

Features:

• Symmetric operation up to 2.048 Mbps

• 10BASE-T Ethernet port

• High-performance Ethernet bridging:
dynamically learns up to 8,192 addresses

• Complete DSLview™ network management
LEDs provide at-a-glance status of modem
and network connections

• User-selectable data rate control

Remote Office Applications

Remote office network connectivity to the central site: remote offices can simply connect the 300S to
their LAN and use the symmetric SDSL service to tap into their corporate network.

Campus Applications

Campus networks: within a private network the 300S may be used to connect LANs in separate buildings.
