Introduction
Simpact provides a variety of user-programmable, wide-area network (WAN) connec-
tivity solutions for real-time financial, defense, telecommunications, and process-
control applications. Simpact software includes a wide variety of legacy and specialty
protocols that run on Simpact’s intelligent communication processor (ICP) boards.
The protocol software is independent of the hardware and operating system environ-
ment.
1.1 Protocol Overview
The Synchronous Link Control (SLC) protocol is a legacy protocol used within the air-
line industry for wide-area network communications. The protocol features synchro-
nous transmission of blocks of characters that contain data or control information.
Full-duplex operation (simultaneous transmission and reception) as well as error
detection and retransmission capability allow SLC to provide efficient and reliable data
transfer at line data rates up to 19200 bits per second.
1.2 Supported Hardware
Section 1.2.1 and Section 1.2.2 briefly describe the currently supported hardware and
operating system environments. Refer to the Simpact References on page 12 for the
applicable hardware installation documentation and user’s guide for your particular
hardware environment.
