Early model 464G key telephone set A business telephone system is a multiline system typically used in business environments, encompassing systems ranging from small key telephone systems (KTS) to large private branch exchanges (PBX). A business telephone system differs from an installation of several telephones with multiple central office (CO) lines in that the CO lines used are directly controllable in key telephone systems from multiple telephone stations, and that such a system often provides additional features related to call handling. Business telephone systems are often broadly classified into key telephone systems, and private branch exchanges, but many hybrid systems exist. A key telephone system was originally distinguished from a private branch exchange (PBX) in that it did not require an operator or attendant at the switchboard to establish connections between the central office trunks and stations, or between stations.

Technologically, private branch exchanges share lineage with central office telephone systems, and in larger or more complex systems, may rival a central office system in capacity and features. With a key telephone system, a station user could control the connections directly using line buttons, which indicated the status of lines with built-in lamps. A 1930s key telephone for a private branch exchange. Key telephone systems are primarily defined by arrangements with individual line selection buttons for each available telephone line. The earliest systems were known as wiring plans and simply consisted of telephone sets, keys, lamps, and wiring.

Key was a for a customer-controlled switching system such as the line-buttons on the phones associated with such systems. The wiring plans evolved into modular hardware building blocks with a variety of functionality and services in the 1A key telephone system developed in the in the 1930s. Key systems can be built using three principal architectures: electromechanical shared-control, electronic shared-control, or independent key sets. New installations of key telephone systems have become less common, as hybrid systems and private branch exchanges of comparable size have similar cost and greater functionality. Electromechanical shared-control key system [ ]. A typical rotary dial key telephone: the Western Electric eighteen-button Call Director, manufactured from 1958 to the early '80s.

Before the advent of, key systems were typically composed of electromechanical components () as were larger systems. The systems marketed in as the 1A, 6A, 1A1 and the are typical examples and sold for many decades. The 1A family of (WECo) key telephone units (KTUs) were introduced in the late 1930s and remained in use to the 1950s. 1A equipment was primitive and required at least two KTUs per line; one for line termination and one for station (telephone instrument) termination. The telephone instrument commonly used by 1A systems was the WECo. Introduced in 1953, 1A1 key systems simplified wiring with a single KTU for both line and station termination, and increased the features available. As the 1A1 systems became commonplace, requirements for intercom features grew.

That's probably just what the victims of these serial killers thought as they wandered into the grasp of these butchers like flies caught in the web of a cold, remorseless spider. Remember what neighbors and friends always seem to say about serial killers and mass murderers: 'He might have been a little strange, but he was quiet and kept to himself. I never thought he'd do anything like this.' When you put together an inability to feel guilt with a perverse desire to inflict physical suffering, you have a lethal killing machine that is all the more dangerous because he often looks just like everyone else.
