November 1997
When using an 8546 DSL card in the DSLAM, the DSLAM can be configured to
interoperate with up to four 5446 RTUs. The 5446 RTU operates as an IP
forwarder at speeds up to 7 Mbps. This RTU supports up to 32 end-user systems
with individual IP addresses or subnets.
The following illustration shows a HotWire network configuration from the
8800 DSLAM to multiple RTUs. (Stacked 8600 DSLAMs can also be used in
place of an 8800 DSLAM.)
