A multiple function lock comprising a body, an engaging element having a first end and a second end, a locking mechanism for securing the first end and the second end of the engaging element to the body, and a gate mechanism for selectively concealing or revealing a passage in the body through which the second end may move to unlock the lock. It is provided that the armature comprises at least one groove edge region element formed andor displaced by means of mechanical deformation of the main body and acting upon the electrical conductor for the purpose of defined positioning andor fixation. An aggregate appliance in the mobile data network defines high-level commands, which each have a corresponding set of steps that are performed when the high-level command is executed. The actuator members include cooperating detents that selectively release the actuator members as the carrier assembly reaches predetermined positions along the sheath for deploying the clip from the carrier assembly, and that collapse the splines to allow removal of the apparatus after deploying the clip. When the lock unit is moved toward the first position, the restrictor moves together with the lock unit to detach from the cable so as to allow the other end of the cable to disassemble from the housing. A controllable parameter of the conference call is dynamically and automatically modified to positively affect the determined QoE of the receiving party when the QoS is below a designated minimal QoE threshold.
