redundancy to quickly switch out a defective line card
and switch-in the back-up line card.

Each channel within the XRT73L04 can be config-
ured to support the E3 (34.368 Mbps), DS3 (44.736
Mbps) or the SONET STS-1 (51.84 Mbps) rates. Fur-
ther, each channel can be configured to operate in a
mode/data rate that is independent of the other chan-
nels.
Two methods are available to select the data rate for
each channel of the XRT73L04.
SELECTING THE DATA RATE
1.1
For the following disscussion the reader should refer
toTable 2 to determine the appropriate Address for
each command register of each channel in the
XRT73L04. The command register description refers
to CR(x)-(n), where (x) = 0 to 7 and (n) refers to a par-
ticular channel of the XRT73L04.
