MODULES (NXT1HSSI) > HSSI MENUS > CONFIG
Write security: 5; Read security: 5
Provides configuration parameters for the HSSI interface including data clocking.
MODULES (NXT1HSSI) > HSSI MENUS > CONFIG > PORT NAME
Read security: 5
Accepts any alpha-numeric name up to 16 characters long, to uniquely identify the HSSI interface on the
NxT1 HSSI and NxT1 HSSI/V.35 Option Modules
MODULES (NXT1HSSI) > HSSI MENUS > CONFIG > TX CLK
Write security: 5; Read security: 5
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.
MODULES (NXT1HSSI) > HSSI MENUS > CONFIG > CTS (V.35)
Write security: 5; Read security: 5
(Available only on the NxT1 HSSI/V.35 Option Module - P/N 1200346L2.) Determines the behavior of the
Clear To Send (CTS) signal. If set to
NORMAL, CTS will follow the Request To Send (RTS) signal. If set to
FORCED ON, CTS will always be asserted.
MODULES (NXT1HSSI) > HSSI MENUS > CONFIG > DSR (V.35)
Write security: 5; Read security: 5
(Available only on the NxT1 HSSI/V.35 Option Module - P/N 1200346L2.) Determines the behavior of the
Data Set Ready (DSR) signal. If set to
NORMAL, DSR will generally be asserted when the interface is
capable of passing data. If set to
FORCED ON, DSR will always be asserted. If set to REMOTE DTR, the value
of DSR will track the value of the remote unit’s DTR signal.
MODULES (NXT1HSSI) > HSSI MENUS > CONFIG > IFCE AUTO DEACT
Write security: 5; Read security: 5
This feature allows a user to set an active DS1 threshold that is used to control the status of the module’s
DTE interface. If the number of active DS1 links falls below the threshold while this setting is Enabled, the
module’s DTE interface will be deactivated. The module will not automatically restore operation on the
DTE interface until the number of DS1 links reaches the threshold value. The DTE interface may be
manually activated.
When using the NxT1 HSSI/V35 Module in V.35 mode, Data Set Ready (DSR) and Data
Carrier Detect (
DCD) are always active.
The Interface Automatic Deactivation feature is not available when CA (data
Communication equipment Available signal) is configured
OFF or DCD (Data Carrier
Detect) is configured
FORCED ON.
