Two System Access Ring and a System Access Originate Only button are
assigned to analog data stations connected to an MLX telephone using an
MFM, digital data stations, and ISDN 7500B data modules used in modem

The system treats each data station as if it were a 34-button telephone.
This procedure is used only to change or add the following types of System
Access or Intercom buttons: Ring, Voice, Originate Only (Ring or Voice), and
Shared (System Access Only, Ring or Voice). See "Assign Lines/Trunks or
Pools to Data Stations" instructions for assigning outside lines/trunks,
Loudspeaker Page, or Pool buttons (Hybrid/PBX only) to data stations.
Hybrid/PBX only: You cannot change the factory setting for Call buttons
assigned to QCC operator positions. You cannot assign System Access,
Ring, Voice, Originate Only, or Shared buttons to QCC operator positions.
System Access or Intercom buttons can be assigned to only the first 10
buttons on a data station.
You can assign a combination of up to 10 System Access or Intercom Voice,
System Access or Intercom Ring, System Access or intercom Originate Only
(Ring or Voice), or Shared System Access (Ring or Voice) buttons to each
data station (excluding QCC operator positions).
You can remove System Access or Intercom buttons, but at least one System
Access or Intercom Ring or System Access or Intercom Voice button must
remain on the data station.
System Access and Intercom buttons are centrally programmed and cannot
be programmed by individual data station users.
To speed programming, dial codes are shown starting in step 8. If you
prefer, you can program by selecting items from the display instead of using
programming codes.
