MODULES (ASYNC232) > CONFIGURATION > DIALOUT > DTR DIAL NUMBER

This field is only active when outgoing calls are enabled and DIALOUT METHOD is set to DTR DIAL. If a

phone number is entered here, it will be dialed when DTR goes active.

MODULES (ASYNC232) > CONFIGURATION > DIALOUT > CALLOUT PROTOCOL

Write security: 3; Read security: 5

This field determines what type or resource will be allocated and the data protocol that will be used for an

outgoing call attempt for the port. The following selections are available:

MODULES (ASYNC232) > CONFIGURATION > DIALOUT > OUT ISDN CALL TYPE

Write security: 3; Read security: 5

When CALLOUT PROTOCOL has been set to ISDN PPP, this field determines what type of ISDN call will be

made when a call is attempted. The value must match the network services provisioned for the PRI or BRI

interface that the call will be carried on. This field is not present and ignored when the

CALLOUT PROTOCOL

ANALOG MODEM.

ANALOG MODEM

An outgoing call attempts to allocate a modem resource and make an

analog call. Asynchronous data is passed unmodified between the

Async-232 Module port and the allocated modem. The analog modem

resource is freed when the call is hung up.

ISDN PPP

An outgoing call attempts to allocate an ISDN resource and make a

digital call. Both ends of the call must be using PPP as the protocol to

communicate across the link. The Async-232 Module port performs

PPP Async-to-Sync conversion between the asynchronous DCE port

and the synchronous ISDN link. This conversion is the standard method

of transporting PPP frames available in ISDN Terminal Adapters from

ADTRAN and other manufacturers. The PPP Async-to-Sync protocol

complies with the Internet Engineering Task Force (IETF) RFC 1662.

For the ISDN call to be routed outside ATLAS 830, a PRI or BRI

interface must be connected to the system and be correctly configured.

DATA 64K

Directs the call control software to request an unrestricted 64 kbps

circuit. The default call type for ISDN service is Data 64 kbps.

DATA 56K

Directs the call control software to request a 64 kbps data circuit that is

rate-adapted to 56 kbps. It is intended for use in circumstances where

interoperability with Switched 56 service is desired.

AUDIO

Directs the call control software to request a 3.1 kHz audio circuit as the

bearer capability for outgoing calls. The Audio option is used with an

ISDN line configured for voice service. Selecting an Audio call type

guarantees a digital end-to-end ISDN connection.

SPEECH

Speech direct the call control software to request a µ-Law speech circuit

as the bearer capability for outgoing calls. The Speech option is used

with an ISDN line configured for voice service. A Speech call type does

not guarantee and end-to-end digital connection with some local and

long distance providers.
