8 Terminal Adapters

TA(s) or Terminal Adapters allow the DVST to communicate over digital ISDN telephone lines.

8.1ISDN Connection (Terminal Adapter)

Connection to an ISDN line is via a terminal adapter and Port 0. On systems using dual ISDN lines both Port 0 and Port 1 should be connected.

The type of cable required to connect to the terminal adapter can vary.

DUALISDN=	...Sets dual ISDN support ON or OFF
	(default, on)
ISDN=	...Sets ISDN for ATMODE, DIRECT, X21 mode
	(default, ATMODE)

DIRECT

DIRECT mode relies upon the terminal adapter dialling a stored number or a network only accessing a single remote point. Also used for Demo mode (chapter 7)

ATMODE

ATMODE refers to Hayes AT dialling where the numbers to be dialled are stored in the DVST dialling menu, also used for Dedicated Micros Terminal Adaptor TA04
