Abstract: A method and apparatus for protocol conversion using channel associated signaling (CAS) is disclosed. A protocol conversion system is located logically between a first signaling system and a second signaling system, in which the first signaling system uses the Common Channel Signaling (CCS) protocol and the second signaling system uses CAS, which is incompatible with CCS. The protocol conversion system receives a first message from the first signaling system that conforms to the CCS protocol, converts the first message to one or more second messages that conform to the CAS protocol, and communicates the one or more second messages to the second signaling system, whereby a voice conversation is established between the first signaling system and the second signaling system. The protocol conversion system preferably comprises a universal protocol converter coupled to a CAS module.

Abstract: A process is disclosed for the manufacture of a liquid detergent composition comprising a sulphiting agent and an enzyme system. Said enzyme system and said sulphiting agent interact together so as to generate odors which result in an odor deviation in said detergent composition. In the process of the invention, said enzyme system and said sulphiting agent are intimately mixed together separately from the remainder of the detergent composition so as to generate said odors outside the remainder of said detergent composition. Also disclosed is an enzyme premix consisting essentially of said enzyme system and said sulphiting agent.
