International Classification:

H04J 324

US Classification:

370 62

Abstract:

An initialization arrangement is disclosed that allows call services defined in service profiles stored in a switching system to be enabled for individual terminals in a multipoint configuration without requiring assignment of terminal endpoint identifiers or virtual channel identifiers at subscription time. The call services are enabled for a terminal when the terminal transmits two identifiers to the switching system, one identifier defining the terminal and the other identifier defining a service profile. The switching system includes the identifier of the service profile in broadcast messages to address terminals with features defined by that service profile. Two embodiments of the invention are disclosed, one applicable in a narrowband integrated service digital network (ISDN) and the other applicable in a broadband ISDN (BISDN).

US Classification:

271272

Abstract:

A sheet material feeding mechanism for use in a duplex duplicating machine. A pressure roller extends laterally across a sheet path for engaging the blank side of a previously imaged copy sheet. A feed roller assembly forms a nip with the pressure roller through which the sheet is fed. The feed roller assembly includes a pair of feed rollers mounted on the outside of a pair of support members for positioning the feed rollers near the marginal edges of the sheet to preclude tracking the imaged side of the sheet. The feed rollers are axially adjustable for accommodating different sheet sizes.
