A controller selectively connecting and disconnecting extensions from a telephone line includes a plurality of extension connector ports selectively connected to a communication device and a plurality of relay switches. The correlating may be performed by a matched filter andor a correlator. Rather than storing the operation codes associated with their respective threads and providing those operation codes to an arbitration module for execution, each of the thread controller stores operation code identifiers that are submitted to the arbitration module. For this purpose, the bus subscribers use a defined mathematical operation to calculate a common first check value which is compared with a second check value. An actuator mechanism is operatively associated with the clamping arm for moving the clamping arm linearly to bring the first clamping portion of the arm into clamping engagement with the first side of the connector and then pivoting the clamping arm to bring the second clamping portion of the arm into clamping engagement with the second side of the connector. More particularly, the compounds are useful for the treatment andor prevention of diseases and disorders in which modulation of the activity of hormone sensitive lipase is beneficial.
