Off-Premises Stations
Stations which are located at a considerable distance from the parent communication system,
and require special circuit terminating arrangements at the system.
On-Premises Stations
Stations which are installed on the same premises as the PBX, or which can operate
satisfactorily with the system when installed in adjacent premises without special circuit
arrangements
Overlap Outpulsing
A feature used in the SX-200 EL/ML system when making trunk calls. It results in dial pulses
(or tones) being outpulsed prior to the receipt of all required digits from the user, the purpose
being to reduce the time needed to process the call.
PCB
Printed Circuit Board.
PCM
Pulse Code Modulation.
PKM
Programmable Key Module
Peripheral Equipment
All those external equipments which are connected to the SX-200 EL/ML system, such as
stations, telephones, trunks, attendant consoles, and maintenance terminals.
Peripheral Interface Card
A card which provides the interface facilities between the external peripheral equipments, such
as stations, trunks and attendant consoles. A prime function is to convert the external analog
inputs to the internal digital PCM signals (and conversely convert digital PCM to analog output).
