Features
.
Ensure that both the originating and destination datasets are both in
the same Operating Mode (asynchronous or synchronous), as pro-
grammed in CDE Form 11 (Data Circuit Descriptor).
Programming
Assign Feature Access Code 28 (ADL Call Setup) and Feature Access
Code 29 (ADL Disconnect) in CDE Form 02 (Feature Access Codes).
Enable COS Option 900 (Data Station Queuing). When COS 900 is enabled
on a voice telephone, queuing to a busy data destination is allowed on an
ADL call.
Program ADL Auto Baud, and Operating Mode (Synchronous or
Asynchronous) in the subform of CDE Form 11 (Data Circuit Descriptor).
Operating Mode applies only to DATASET 2100 Series datasets.
To associate a voice telephone with a dataset, enter a valid extension
number for the voice telephone in the AVL field of CDE Form 12 (Data
Assignment).
Feature keys on SUPERSET DN and SUPERSET DN telephones can be
programmed to originate and disconnect data calls (see Feature Keys).
Operation
ADL Call Originate
If the Originating dataset does not have ADL Autobaud:
l

.
_
.
Dial the ADL access code (if the associated dataset is not idle; reorder
tone is heard and the SUPERSETtelephone displays the message
" P LEASE TRY LATER" ) .
Dial the digits of the destination.
A high pitched connect tone is heard (if the destination is busy, then
busy tone is heard).
The originating party hangs up the voice telephone and the call is
switched to the associated dataset (" H ANG UP" or " N EW CALL"
prompt can also be used).
If the SUPERSETtelephone has a voice party on Hold, the CANCEL
key establishes the data call and transfers the voice call to the party on
hold.
When Originating dataset has ADL Autobaud:
.
9109-09&l
05-NA
Dial the ADL access code (if the associated dataset is not idle; reorder
tone is heard and the SUPERSET telephone displays the message
" P LEASE TRY LATER" ) .
Dial the digits of the destination (busy tone is heard if the destination is
busy).
When ringback tone is heard, the originator must enter the autobaud
character (usually carriage return) so that the dataset can determine
