New PBX networking features based on ISDN PRI services included support of incoming ANI, and call-by-call service selection (CBCSS). CBCSS allows a PBX system administrator to define the communications service supported by individual ISDN PRI bearer communications channels. A single T1-carrier trunk circuit, supported by ISDN PRI service, could be used for a variety of services between the PBX system and the network exchange carrier’s central office switching system. For example, several bearer channels could be designated incoming DID trunks, others could be designated two-way CO trunks, and others could be designated clear channel data circuits.
The concept of the PBX as a mobility server can significantly improve call coverage, reduce lost or abandoned calls, and increase the number of successful call attempts between caller and called parties. Another category of mobile workers consists of station users who require a telephone away from the formal office environment. Known as teleworkers, these station users require their high-performance telephones to function away from the workplace and receive incoming calls redirected to their remote desktop.
The cost of LAN equipment, at first significantly more expensive than PBX data option pricing, declined rapidly during the 1980s, making it a far more attractive data networking solution than a PBX. PBX data modules, once considered a high-speed option, were viewed as slow when compared with LAN transmission rates. Dreams of the PBX becoming the data networking solution died by the late 1980s when LAN technology matured and network routers first entered the market. Shipment levels of PBX data stations (integrated and stand-alone) never exceeded 3 percent of total annual shipments.
