PC Platforms (PC/PBX and PC/ISDN)

The PC/PBX MicroChannel Architecture platform is the same as the PC/PBX platform, but is intended for use with the IBM PS/2 Model 50 and above.

Applications

The platforms are ideal for professionals and managers who perform many different tasks during the day. The platform architecture permits different PC applications to access its resources alter- natively or simultaneously. The PC/PBX Platforms support the 7400 Series voice terminals.

Potentially, a user could hold a voice conversation, be asynchronously connected to a host or PC, or conduct a 64 kbps 3270 session to a mainframe over a single twisted-pair connection. This eliminates the need for such multiple PC communications adapters as modems and coax cards.

Capabilities

Used in conjunction with PC applications software, the PC/PBX Platform provides the hardware architecture at the desktop for:

High-speed PC-to-PC communication

Access to asynchronous host environments

Access to the synchronous 3270 environment

Advanced telephone management capabilities

The PC/PBX Platform can also run the PC/PBX Connection software for integrating voice and data applications at the desktop. Thus, the platform supports all of the following:

Synchronous communication via 3270 emulation with file transfer capabilities

Asynchronous communication via VT® 100, VT102, and 4410 terminal emulation at speeds up to 19.2 kbps

Digital Multiplexed Interface (DMI) connectivity at 64 kbps

High-speed PC-to-PC communication for error-free file transfers at speeds up to 64 kbps via such standard asynchronous file transfer protocols as XMODEM and KERMIT
