Chapter 3. Operation

RX RATE AND TX RATE

Displays the current average receive and transmit data rate on the

HSSI interface.

CONFIG

Read Security: 5

Provides configuration parameters for the HSSI interface including data clocking.

When using the NxT1 HSSI/V35 Module in V.35 mode, Data Set Ready (DSR) and Data Carrier Detect (DCD) are always active.

TX CLOCK

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.
