5.6.1.6(ConfigInterface) – DATA INTERFACE

Data interface for each card (modulator or demodulator) is auto detected. If grouped as a modem, the operating data interface will be the one installed in the demod card (interface on the modulator is not required). If a QDI interface is installed and a modem is grouped, then either it or the interface installed on the Demod can be selected. The card can support one of the following:

•RS-422 (RS-530)

•V.35

•RS-232

•G.703 (for single T1 or E1)

•HSSI

•QDI (Quad Drop & Insert)

The blinking cursor will point to the supported data interface for the card being installed, then press ENT

Interface: RS422 V.35 RS232

HSSI ASI G.703 QDI NONE

If grouped as a modem and RS422, V.35 or RS232 are selected, the following sub menu will be displayed:

RTS/CTS operation: (▲ ▼, ENT)

Loop,RTS Controls Tx Out

The option is changed using the STarrow keys. The user should then press ENT. The following options are possible:

RTS/CTS Loop, No Action RTS and CTS are looped, so that CTS echoes the state of RTS, but RTS does not control the ON/OFF state of the carrier.

Loop, RTS Controls Tx Out RTS and CTS are looped, so that CTS echoes the state of RTS, and RTS controls the ON/OFF state of the carrier (in other words, the modem will not bring up its TX carrier until RTS is asserted.

Ignore RTS, Assert CTS

RTS is ignored, and CTS is asserted unconditionally.
