MODULES (NXT1HSSI) > HSSI MENUS > STATUS > CA

Read security: 5

(Not applicable when using the NxT1 HSSI/V.35 Option Module - P/N 1200346L2.) Displays the status of the data Communications equipment Available (CA) 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 > STATUS > LA AND LB

Read security: 5

Displays the status of the loopback circuit A and B signals. LA and LB are asserted by the DTE to enable a loopback on the DCE and its associated data communications channel. There are four loopback options:

LA	LB	LOOPBACK
Off	Off	No Loopback Active
On	On	Local DTE Loopback is Active
On	Off	Local Line Loopback is Active
Off	On	Remote Line Loopback is Active

MODULES (NXT1HSSI) > HSSI MENUS > STATUS > LC

Read security: 5

Displays the status of the loopback circuit C signal. LC is an optional loopback request signal from the DCE to the DTE, requesting the DTE to provide a loopback path to the DCE.

MODULES (NXT1HSSI) > HSSI MENUS > STATUS > TA

Read security: 5

Displays the status of the data Terminal equipment AVAILABLE signal. TA will be asserted by the DTE (independently of CA) when the DTE is prepared to both send and receive data to and from the DCE. Valid data transmission should not commence until CA has also been asserted by the DCE. If the data communications channel requires a keep alive data pattern when the DTE is disconnected, then the DCE shall supply this pattern while TA is de-asserted.

When using the NxT1 HSSI Module (1200346L2 only) in V.35 mode, TA displays the status of the Request to Send (RTS) signal. When RTS is active in a V.35 configuration, Clear to Send (CTS) is also active.

MODULES (NXT1HSSI) > HSSI MENUS > STATUS > RX RATE

Read security: 5

Displays the current average receive data rate on the HSSI interface.

MODULES (NXT1HSSI) > HSSI MENUS > STATUS > TX RATE

Read security: 5

Displays the current average transmit data rate on the HSSI interface.
