(Available only on the NxT1 HSSI/V.35 Option Module - P/N 1200346L2.) Determines the behavior of the Data Carrier Detect (DCD) signal (also called RLSD on some interfaces). If se tot Normal, DCD will generally be asserted when the interface is capable of passing data. If set to Forced On, DCD will always be asserted. If set to Remote RTS, the value of DCD will track the value of the remote unit’s RTS signal.

DCD is not configurable when the Interface Automatic Deactivation (IFCE AUTO DEACT) feature is ON.

MODULES (NXT1HSSI) > HSSI MENUS > CONFIG > CA

Write security: 5; Read security: 5

(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.

MODULES (NXT1HSSI) > HSSI MENUS > TEST

Write security: 4; Read security: 5

Provides access to testing functionality for the HSSI and HSSI/V.35 interfaces for the NxT1 HSSI or NxT1 HSSI/V.35 Option Modules.

MODULES (NXT1HSSI) > HSSI MENUS > TEST > PORT

Read security: 5

Indicates the operating port number. The NxT1 HSSI and NxT1 HSSI/V.35 Option Modules have one available HSSI (or HSSI/V.35) interface.

MODULES (NXT1HSSI) > HSSI MENUS > TEST > LOCAL LPBK

Write security: 4; Read security: 5

Activates a local loopback on the HSSI interface. The following local loopbacks are available:

LOCAL LINE Activates a loopback of the received T1 data streams at the DTE interface.

T1 FRAMER Activates a loopback of the received T1 data streams after the data has been processed by the T1 framer located on the NxT1 HSSI or NxT1 HSSI/V.35 Option Modules. All data received during an active T1 FRAMER local loopback will be regenerated (re-framed) and transmitted back out the DTE interface.

LOCAL DTE Activates a loopback of all data received at the DTE. All data received during an active LOCAL DTE loopback will be echoed out the DTE interface.
