AT&T AT&T manual Communications Access Manager CAM, Starlan Interface Circuit Pack, 216

●Communications Access Manager (CAM)

CAM is an MS-DOS applications program that provides an enhanced calling interface and terminal emulation for PCs connected to System 25 or a STARLAN NETWORK. This connection must be through a DLC or a STARLAN NETWORK that is, in turn, connected to System 25 by a STARLAN CP. Refer to the Communications Access Manager (CAM) Program feature description for a more detailed description of the program.

STARLAN INTERFACE Circuit Pack

The STARLAN INTERFACE CP (ZTN84) requires a single modular connection to the STARLAN NETWORK (see Figure 2-42). It provides an interface between System 25’s Time Division Multiplex (TDM) bus and STARLAN NETWORK’s packet switched network. The STARLAN CP provides four full-duplex data connections at speeds up to 9,600 bits per second.

The STARLAN CP operates in two modes: Gateway Mode and Bridge Mode. Gateway mode supports connections from System 25 data terminals to STARLAN NETWORK UNIX® system hosts, or from STARLAN NETWORK UNIX system hosts or client workstations to System 25 hosts or modem pools. In Bridge Mode, the STARLAN CP passes the STARLAN NETWORK’s Universal Receiver Protocol (URP) through System 25 to a local or remote PC. This is referred to as Bridge Mode and provides a through connection between PCs running ACCESS and a STARLAN NETWORK. The proper mode (Bridge or Gateway) is auto- selected by the system.
