Abstract: An improved grill brush for cleaning grill grates and a cleaning system including a grill grate specifically adapted for use with the disclosed grill brush includes a head portion and a handle portion. A plurality of metallic bristles is mounted to and extends from at least one surface of the head. Some of the bristles are made of a first metal and others of the bristles are made of a second metal. In one embodiment, one metal is stiffer than the other metal, the stiffer bristles are shorter than the more flexible bristles, and the bristles are arranged so as to form rows of short, stiff bristles parallel to rows of long, flexible bristles. In this embodiment, the length and configuration of the bristles is generally specified for the grill grate with which the brush is intended to be used to facilitate cleaning the top and side portions of the grill grate. In another embodiment, the bristles are fabricated of at least two different materials and are of the same length.

Abstract: A improved protocol for communication between a SS7 gateway and a Remote Access Server (RAS). The gateway connects to the SS7 network and supports, e.g., ISUP and TUP protocols. The gateway relays call handling and administrative events over an Internet Protocol (IP)connection to the RAS using the protocol.
