MicroChannel
TM
bus PCs in the DCP environment. Supports common, open data inter-
face with PC/ISDN platform. Supported software includes PC/PBX Connection (for
advanced phone management, access to synchronous and asynchronous hosts, and
high-speed PC-to-PC communication) and E78 Plus. Works with any 7400-series
phone.
PC/ISDN Platform—PC expansion card and software for XT/AT bus PCs in the BRI
environment (DEFINITY G2 and 5ESS). Supports common, open data application inter-
face with PC/PBX Platform. Supported software includes E78 Plus and high-speed
PC-to-PC file transfer applications.
E78 Plus/ISDN—Software written to the open data applications interface which provides
full 3270 terminal emulation and fast file transfer in IBM environments.
3270 Data Module—The 3270C Data module connects to an IBM 3274 or 3174 Clus-
ter Controller and converts DCP data from the PC platform products to the IBM Coax A
format to access IBM mainframes for 3270 terminal emulation and fast file transfer.
The above PC platform products allow PC users to:
Dial calls from the PC and use customized phone features from the keyboard,
including a personalized phone directory, log of calls received and made, note-
taking on calls, and phone message retrieval.
Connect to a variety of asynchronous hosts and to IBM mainframes, allowing file
transfer to and from the mainframe using standard IBM file transfer protocols and
the standard DCA IRMA board user interface.
Transfer files from PC to PC at rates up to 1.2 kbps over a 64 kbps facility using
a PC package from Hilgraeve, Inc.
Switch back and forth from the above capabilities to DOS programs at the touch
of a key, when the PC/PBX application is run in the background.
