The Analog Termination

Abstract

Digital switching systems are frequently used to replace old and obsolete analog switching systems. The digital switch must have suitable analog terminations which are directly compatible with the existing analog telephone plant. In public applications, the digital switch should not exclusively require digital telephone instruments since it would be very difficult and costly to introduce a new type of telephone at the time of switching system cutover. In some cases, customers might already own their telephones and the new switching system should not preclude their use. In private applications, there is more flexibility in introducing digital telephones. But the private digital switch must have suitable analog terminations for trunks.
