NOTES:
1. Do not assign System Access Voice (SA Voice) buttons to data
communications equipment.
2. You must use PRI facilities with a digital data service such as ACCUNET
Switched Digital Service, a Software Defined Network (SDN), T1
Switched 56 facilities, or NI-1 BRI facilities for digital data calls.
3. T1 facilities that are not using Switched 56 service can be used for
modem data and analog voice calls and can be assigned to telephones to
allow the voice user to make and receive voice calls using these types of
facilities.
The following line button assignments are factory set for Hybrid/PBX mode and
are prerecorded on the Button Diagram on Data Forms 1a and 1b:
■ One System Access Originate Only (SA Orig Only) button and two System
Access Ring (SA Ring) buttons are assigned to all data equipment
connected to an 012 T/R, 016 T/R, or 008 OPT module.
■ One System Access Originate Only (SA Orig Only) button, one System
Access Ring (SA Ring) button, and a System Access Voice (SA Voice)
button are assigned to all data equipment connected to a digital extension
jack on an 008 MLX or 408 GS/LS-MLX module. Remove the SA Voice
button (see Form 5c, page 1).
The factory settings can be changed; however, the settings should be adequate to
meet most user needs, since System Access lines can be used to make both
inside and outside data calls. Each data extension must have at least one SA
button, or two SA buttons for making 2B Data calls. If making 2B Data calls with
two personal line buttons, you must also have two SA buttons.
If you want an ISDN terminal adapter data station to make and receive outside
data calls on a specific outside line/trunk, assign a personal line button. To make
calls on a personal line, set the Automatic Line Selection to that line.
Assigning Pools and Lines/Trunks
(Hybrid/PBX Mode Only) 5
If you want the voice and data station to make and receive outside calls on a
specific trunk pool, assign a Pool button.
To dedicate a specific line/trunk or pool to receive outside data calls, assign a
personal line or pool to a data station or DHG.
To dedicate specific lines/trunks for use in data communications only (such as PRI
channels or other special data lines), consider grouping those lines/trunks in a
pool.
