ATLAS 800 Series System Manual NxT1 HSSI Option Module
HSSI/V.35 Menus
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.
T1:#Tx Chan
HSSI port number of channels in use
Rx Rate
Displays the current average receive data rate on the HSSI interface.
Tx Rate
Displays the current average transmit data rate on the HSSI interface.
Submenu Description
Port
Indicates port number.
Port Name
Select port name from drop-down list.
Tx Clk
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.
CTS (V.35)
Clear to send: Normal, Forced On
DSR (V.35)
Data set ready: Normal, Forced On, Remote DTR
Ifce Auto Deact
Interface auto deactivation: Off, On
DCD (V.35)
Data carrier detect: Normal, forced On, Remote RTS
CA (HSSI)
(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.
