LOCK
Controls the clock used by the NxT1 HSSI/V.35 Module to accept
the transmit (TX) data from the DTE. This is usually set to
Normal
.
If the interface cable is long, causing a phase shift in the data, the
clock can be set to
Inverted
. This switches the phase of the clock,
which compensates for a long cable.
CA
(Not applicable in V.35 mode.)
Asserts the data Communications equipment Available signal from
the DCE. CA will be asserted by the DCE, independently of TA,
when the DCE is prepared to both send and receive data to and
from the DTE. This indicates that the DCE has obtained a valid data
communications channel. Data transmission should not commence
until TA has also been asserted by the DTE.
LC
(Not applicable in V.35 mode.)
Enables the Loopback Circuit C signal from the DCE. LC is an
optional loopback request signal from the DCE to the DTE,
requesting the DTE provide a loopback path to the DCE.
When using the NxT1 HSSI/V35 Module in V.35 mode, Data Set Ready (DSR) and Data
Carrier Detect (DCD) are always active.
