Introduction to the Hotwire DSLAM

When using an 8546 DSL card with the 5446 RTU 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.
When using an 8546 DSL card with the 5546 RTU in the DSLAM, the DSLAM
can be configured to allow an end-user to utilize an external router with a
V.35/EIA-530 interface. The 5546 RTU operates at speeds up to 7 Mbps
supporting up to 32 hosts or subnets behind the external router connected to the
5546 RTU. As most serial interface speeds are set at the T1/E1 rate, the 5546
operational speed should be set accordingly.
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.)
