Trunks The Connections Between A PBX And CO Switch Are Called Trunks. Trunks Are Usually Large-Capacity Connections. Businesses Configure Their Trunks Depending On Their Telephone Systems, Business Needs, and Employee Calling Patterns. PBXs Can Connect To Three Types Of External Networks.

Extension Lines The Connections From Individual Telephone Sets To The PBX Are Called Lines, Or Extension Lines. Each Line Is Formed By A Twisted Pair Of Copper Wire, And Is Assigned A Telephone Extension Number By The PBX Administrator.

Equipment Cabinet The Equipment Cabinet, A Large Metal Box In The Main Equipment Room, Is The Heart Of The PBX. Much of the Cabinet’s Circuitry Is Contained On Electronic Circuit Cards That Slide Into Slots And Plug Into A Main Processor Board.

Most of Equipment Cabinets Are One Of Two Main Types: Trunk Cards Contain The Circuitry Necessary To Communicate With the CO Switch. Station Cards Contain the Circuitry Necessary To Communicate With Internal Telephone Extensions.

Telephones and Attendant Console Telephone Sets Are Designed To Work With A Particular PBX System. Each PBX Telephone Set Includes Programmable Features That Can Be Enabled Or Disabled By The Company’s Telephone System Administrator.

Administrative Terminal A Computer Workstation Provides Administrative Access to the PBX System. The Company’s Telephone Administrator Uses The System To Configure The Wide Range of Features And Options Available.
