Abstract:

Customers that have groups of stations served from multiple digital switching systems, which frequently include mixtures of PBXs and Centrex, require capabilities that will allow those station groups to operate as one global group. This invention permits customer station groups, including PBXs and Centrexes interconnected by private facilities or by the public switched telephone network (including long distance carriers), to act as a single entity that supports integrated voice and data communications. Advantageously, Integrated Services Digital Network (ISDN) Primary Rate Interface (PRI) facilities are used to carry the communications and signaling to and from the PBXs.

Abstract:

A diagnostic testing device is disclosed. The testing device includes a base member and a cover member which defines an opening for the reception of a liquid specimen. A distribution wheel delivers portions of the specimen to antibiotic units which are circumferentially spaced. Indicator units are in communication with the cover member. A delivery cylinder extends upwardly from each of the antibiotic units toward a respective one of the indicator units. Relative vertical movement between the delivery cylinder and the indicator unit places the cylinder and the indicator unit into an engaging relationship. A change in coloration at an indicator unit indicates a positive reaction.
