A snubber circuit for use with hold circuits employed in telecommunication applications that employ an SCR as the principle control device. The included circuit prevents false hold turn on in response to static discharge. Voice band impedance and ringing signals are not adversely affected by the addition of the circuit to a standard SCR type hold circuit.

Static discharge snubber circuit for silicon controlled rectifier (SCR)

A dual timing circuit for use with a subscriber's telephone circuit operated in response to two manual switch operations to simulate the placement of the subscriber's phone in the 'on-hook' condition for two different predetermined periods of time. One 'on-hook' period being for the operation of transfer circuitry in an associated PABX and the other period being for the initiation of a new call.
