Abstract: A method and system provide for using a single broadband SS7 signaling gateway for multiple wireless access gateways. One embodiment may have the steps of: forming a cluster of media gateways, each of the media gateways having a respective transcoder; providing at least one first media gateway of the cluster of media gateways having an integrated broadband SS7 signaling gateway, at least one second media gateway of the cluster of media gateways being without an integrated broadband SS7 signaling gateway; and using the at least one first media gateway for SS7 signaling and using the at least one second gateway for resources other than SS7 signaling.

Abstract: A method and system provide for using an integrated broadband and narrowband SS7 signaling gateway with M3UA and point code mapping. In general terms one embodiment of the system has: a single physical media carrying at least one bearer path and at least one signaling link, the physical media being operatively connected to a signaling network; and an integrated media and signaling gateway operatively connected to the physical media, the integrated gateway being a termination for both the bearer path and the signaling link.

Abstract: Refractory lined metal melting furnace for the melting and holding a plurality molten metals or alloys of different composition comprises a melting chamber, a plurality of passages communicating the melting chamber to a plurality of refractory lined, heated holding chambers for holding individual molten metals or alloys therein. The holding chambers are separated from one another by a refractory partition to thereby eliminate contact between molten metals or alloys therein. The holding chambers are selectively communicated one at a time to the melting chamber to introduce a respective molten metal or alloy to respective holding chamber. The holding chambers are communicated to respective take-out wells where each respective individual molten metal or alloy is received without contact with the others for further processing or removal.
