Title: V.F. receivers for use in digital switching systems
Inventor: PING SI LAM
IPC: H04Q1/448
Filed: 1981-11-12
Abstract: A 1VF receiver is used to extract 1VF signalling tone (2,280 Hz) from p.c.m. speech channels using recursive filter techniques. Four filters (FILTER 1; FILTER 2; FILTER 3; and FILTER 4) are used to serve a full 32 channel p.c.m. data stream i.e. each filter serving 8 channels. To test the operation of the receiver test tones are injected into certain of the channels corresponding to each of the four filters. As the normal operation of the channels can not be disturbed, during testing, vacant channels 0 or 16, corresponding to time-slots TSO or TS16, are employed to temporarily transfer channel data while the test is performed. Because of the nature of the recursive filters a channel data overlap period is required both before and after the test. Accordingly during the overlap periods, data in the channel to be injected and the channel to which data is to have data temporarily transferred to it has identical data for a short period of time. To effect this two temporary buffer stores (BS1 and BS2) are employed in the receiver the relevant data being switched to and from the stores (switches S2 and S5) as appropriate. Test results are stored in a test result store (TRS). <IMAGE>

An inner mandrel 75 is slidably mounted within the tubular body and has a ball seat 69 formed for receiving a ball dropped through the well tubing string. The ball and ball seat together form a pressure tight seal whereby tubing pressure in the well tubing string acts on the inner mandrel to slide the mandrel downwardly within the tubular body. Below the inner mandrel is a cocking mechanism including a lockout member 157, Fig 1b, is initially between a detonating pin 181 and a percussion detonator 173. Downward sliding movement of the inner mandrel actuates to displace the lockout member and subsequent release of tubing pressure and upward sliding movement of the inner mandrel exposes the detonating pin to the percussion detonator to actuate the detonator and fire the perforating gun. The firing mechanism may be separated from the gun by dropping a larger diameter ball through the well tubing string to engage a seat 55. The ball and seat form a pressure tight seal whereby pressure in the string acts on mandrel 37 to shear retention pins 41. <IMAGE>
