Data Options and Profiles

During a circuit switched data call, your ADM transports all eight bits of an

asynchronous data character end-to-end as information, rather than

checking or generating a parity bit. V.120 data calls are accepted by your

ADM from endpoints provided the parity setting carried within the call setup

information indicates a valid character size and parity combination: 8-bit

none, 7-bit odd, 7-bit even, 7-bit mark, or 7-bit space. V.120 data calls

initiated from your ADM contain parity setting information in the call setup

information which is fixed at 8-bit no parity regardless of the local mode

parity setting. In other words, no matter what the setting of the parity

option (odd, even, mark, or space), your ADM always originates V.120

data calls with call setup information coded as 8-bit no parity. If the called

V.120 endpoint requires an exact match in parity before it will accept an

incoming call from your ADM, the called V.120 endpoint must be set to 8-

bit no parity.

To set this option from an attached terminal, do the following:

1. Type

set parity value

(for example, set parity odd).

2. Change your data terminal’s parity to match this value. (See your data

terminal’s operating manual for instructions.)

3. Press

RETURN

You can also change the parity option setting of the ADM (when the Autoadjust

option is on) by pressing

BREAK

, typing

and then pressing

RETURN

NOTE:

Using autoadjust only temporarily activates the current speed and parity.

You can store speed and parity by setting the options through the voice

terminal keypad or by copying data option profile pA to p1 (see ‘‘Data

Option Profiles,’’ later in this chapter).
