Abstract: A cable sealing device (10) includes a member (14) includes an elastomeric material and adapted to be fitted into a cable receiving aperture. The member includes a first wall (16) and a second wall (18) spaced apart from the first wall to partially define a cavity (20) between the walls. Each wall includes a cable receiving slot (e.g., 22, 24) formed in the wall. Each wall is deformable away from the respective slot to accommodate a respective cable portion (e.g., 26, 28) extended through the slot so that the wall is biased around the cable portion to minimize any opening around the cable portion passing through the slot. The slots in the respective walls cooperate to provide a redundant seal around a cable portion (30) passing through the member.

Abstract: The present invention provides clear and robust arbitration of which of two system controllers is in control of a telecommunications switching system. Each system controller monitors and actively reports its status to a separate arbitration circuit. The resultant signal from the arbitration circuit tells the system which controller to obey. By feedback of its own output unnecessary switching or ill-defined control states are avoided. In particular, if either both or neither system controllers is reporting itself as OK, the system does not switch controllers. In addition, the arbitration circuit is fed redundant clock signals and support, making it effectively redundant.
