Other Groups

Other groups are assigned to enhance the use of specific system features:

■Pickup groups can be assigned when people need to answer one another’s

calls (see ‘Pickup’’‘ on page 4-34).

■Paging groups are used for extensions that have speakerphones and are located in the same work areas or departments. All members of a group can be paged at once. (Note that the Loudspeaker Paging feature is different; a loudspeaker paging system can support zones for broadcasting to different areas of a company.)

■Coverage groups are described ‘‘Covering Calls’’ on page 4-32.

Data Communications 4

You will not find a great deal about data communications in the Feature Finders earlier in this chapter. Although the system allows data communications, it does so with features that also support other functions. Full descriptions of data communications and the equipment for data communications are included in the Feature Reference and Data/Video Reference. ‘‘Data Communications Adjuncts’’ on page 3-40 also provides information about data communications equipment.

Some data communications setups (called data workstations) include a modem connected to an MLX telephone that is equipped with a Multi-Function Module (MFM). MLX extensions make good data workstations because they require only one extension jack for both the phone and the modem (the modem may be inside or external to a data terminal or PC). A modem may also be attached directly to an MLX extension jack. Alternatively, a modem may be attached directly to an analog extension jack or to a General-Purpose Adapter (GPA) and analog multiline telephone; to operate independently, the phone and GPA must each have an analog extension jack. A modem can also be attached directly to a tip/ring (T/R) jack on a 012, 016 (Release 4.0 and later systems), or 008 OPT module.

An Auto Answer All button must be programmed at an analog multiline telephone that is connected by a GPA to a modem. If you use Auto Dial, Last Number Dial, Saved Number Dial, or Authorization Codes at an analog voice and modem data workstation with a GPA set to Auto operation (for automatic answering of data calls), the user must first lift the handset and then activate the feature. If a feature turns on the speakerphone at the telephone, the GPA does not work properly.

Group and personal desktop videoconferencing systems, high-speed data communications, and Group IV (G4) fax machines are supported through digital Basic Rate Interface (BRI), T1 Switched 56, or Primary Rate Interface (PRI) lines

(see ‘Modules‘ Supporting Lines/Trunks’’ on page 3-7 for more information about these facilities). These arrangements allow high-speed data transmissions through an MLX extension jack that accesses a digital line. An ISDN terminal adapter or other DCE takes the place of a modem for transmitting and receiving data. In some cases, the two B-channels of an MLX extension jack can be combined through system programming of the 2B Data feature; this arrangement
