2 CHANNEL E3/DS3/STS-1 LINE INTERFACE UNIT
PRELIMINARY
REV. P1.1.0
23
In HOST Mode Operation, the TxOFF_(n) input pins
can still be used to turn on or turn off the Transmit
Output Drivers in Channels 0 and 1, respectively.
The intent behind this feature is to permit a system
designed for redundancy to quickly switch out a de-
fective line card and switch-in the back-up line card.

SELECTING THE DATA RATE
Each channel in the XRT73L02 can be configured to
support the E3 (34.368 Mbps), DS3 (44.736 Mbps) or
SONET STS-1 (51.84 Mbps) rates and to operate in a
mode/data rate that is independent of the other chan-
nel.
Two methods are available to select the data rate for
each channel of the XRT73L02.

Refer to Table 2 to determine the appropriate
Address for each Command Register of each chan-
nel in the XRT73L02. The Command Register
description refers to CR(m)-(n), where (m) = 0 to 7
and (n) refers to a particular channel of the
XRT73L02.
