The connection choices and their descriptions are as follows:

Type of connection

Description

Direct

Either:

• Hardwired to a node.

• Connected to a node through a pair of full-time (dedicated)

modems using a dedicated facility.

• Connected to a node via a dedicated port into a

multiplexer and conveyed in the multiplexer’s payload.

Modem
Call/Answer

This choice provides dial-out call to a node and dial-in call
from a node. A

Modem Call/Answer Comline uses the

Hayes

AT command set at 1200, 2400, or 9600 (for AS2000

equipment only) baud.

If a combination of 1200-baud and 2400-baud call/answer
modems are connected to the computer, install the 2400
baud modems with higher Comline numbers than the 1200-
baud modems. If answer-only modems are connected, install
them with higher Comline numbers than the call/answer
modems. If multiple modems are used for alarm reporting,
their phone lines should be installed by the telephone
company or in a PBX (direct inward dial) as a hunt group.
This allows the hunt group master number to be used as an
alarm report number for all nodes. If you configure a Comline
for 9600 baud, that comline cannot be used to query a node
configured for 1200 baud although on incoming calls to
Access Manager, a 9600-baud modem adapts to the baud
rate (1200, 2400, or 9600) of the incoming call.

Modem Answer
Only

Dial-in call (from a node) only. A

Modem Answer Only

Comline (normally used with INWATS lines) uses the Hayes

AT command set on a modem at 1200, 2400, or 9600 baud.

ComDesign Mux

Connection to multiple nodes through a routing multiplexer
such as a ComDesig nRS2000 Statistical Multiplexer. Refer
to the ComDesign Multiplexer manual for proper
configuration of the multiplexer.

X.25 PAD

For use with AS2000 (NCC 2020) only.
