AT&T AT&T manual Communications Access Manager Architecture

COMMUNICATIONS ACCESS MANAGER (CAM) (V2)

The CAM program facilitates communication between workstations on the AT&T STARLAN NETWORK (STARLAN NETWORK) and workstations on System 25. Detailed procedures for using CAM can be found in the CAM User Guide. The material here provides a brief overview of CAM capabilities.

CAM is an MS-DOS application program that provides an enhanced calling interface and terminal emulation for PCs. CAM, combined with System 25’s Third-Party Call Setup feature, provides the capabilities of an integrated voice /data workstation, specifically:

● A 200-entry directory for automatic dialing of voice and data calls

● VT100 terminal emulation with:

—file transfer with error checking

— unattended remote access operation with mail

●On-line HELP that is accessible from almost anywhere within the program.

CAM runs on the AT&T PC6300 or compatible PC with at least 384K bytes of memory, running MS-DOS Version 2.0 or later (when connected to System 25) or MS-DOS Version 3.1 or later (when connected to the STARLAN NETWORK).

The PC running CAM can be connected to System 25 in one of two ways (Figure 2-18):

1. By the PC’s RS-232 COM port to the System 25 via an ADU/DLC connection

2. As a STARLAN NETWORK workstation to the System 25 via the STARLAN Interface CP.

CAM interfaces with System 25’s Command Mode to provide call control. The Third-Party Call Setup feature provides voice call origination.
