Phone Line Options: PBX & Centrex

CalPBX Phone Lines

PBX stands for Private Branch Exchange, which is a private telephone network used at UC Berkeley. Using the PBX phone system allows communication internally (on-campus calls) and externally (with the outside world), using different communication channels like Voice over IP, ISDN or analog (the landlines or desk phones on campus, also used for fax machine and other voice related services).

The following packages are available:

  • PBX Analog Line - This is the standard CalPBX analog line. Some features require that you use a touch-tone telephone set. Others may also require a special analog telephone set that supports use of those features. The analog line is available with voicemail, basic or enhanced.
  • PBX Digital Line - The digital telephone service provides enhanced telephone services. Some features require specific station equipment. Digital telephones used on the Campus Centrex system are not compatible with the PBX and will need to be replaced with Avaya digital telephones when departments switch to the PBX. The digital line is available with voicemail, basic, or enhanced.

For more information please see our Knowledge Base articles on CalPBX.

Centrex Phone Lines

Centrex (central office exchange service) is a service from local telephone companies in the United States in which up-to-date phone facilities at the phone company's central (local) office are offered to business users so that they don't need to purchase their own facilities. Centrex service at UC Berkeley for either analog or digital (electronic) voice lines is provided by AT&T’s telephone switching equipment located at their central office (Telco). Unlike Cal PBX equipment, which is owned by UC Berkeley and housed on the UC Berkeley campus. AT&T’s equipment delivers PBX-like services to some UC Berkeley locations not designated as PBX sites.
