NETWORK ARCHITECTURE COMPATIBILITY
The control unit supporting the terminal devices shall be compatible with the IBM
Systems Network Architecture (SNA) . The control unit shall be defined to the network as an SNA Unit (PU) Type 2 device
capable of supporting, at a minimum, SNA Logical Units (LU) Types 1, 2, and 3.
DATA LINK PROTOCOL COMPATIBILITY
The control unit supporting the terminal devices shall operate using the SNA Synchronous Data Link Control (SDLC) protocol to communicate with a local or remote communications processor.
TRANSMISSION SPEED COMPATIBILITY
The control unit supporting the terminal devices shall be capable of transmitting
and receiving data to or from the communications processor at a rate of at least 9600 bps.
TRANSMISSION CODE COMPATIBILITY
The control unit supporting the terminal devices shall communicate with the terminal
devices and the network using the Extended Binary Coded Decimal Interchange Code (EBCDIC).
COMMUNICATIONS PROCESSOR SYSTEMS SOFTWARE COMPATIBILITY
The control unit and terminal devices shall be initially compatible with the Advanced
Communications Function/Network Control Program (ACF/NCP) Version 2, Release 2. Furthermore,
the control unit and terminal devices must be capable of migrating to ACF/NCP Version
3, Release 1 without modifications to either the control unit or terminal devices.
HOST PROCESSOR SYSTEMS SOFTWARE COMPATIBILITY
The control unit and terminal devices shall be compatible with the Advanced Communications
Function/Virtual Telecommunications Access Method (ACF/ VTAM) Version 2, Release 1
executing in the host computer. Furthermore, the control unit and terminal devices
must be capable of migrating to ACF/VTAM Version 2, Release 2 without any modifications
to either the control unit or terminal devices.
APPLICATION SOFTWARE COMPATIBILITY
The control unit and terminal devices shall be compatible with the IBM Customer Information
Control System/Virtual System (CICS/VS) Version 1, Release 6, and the Polygon Systems,
Inc. INTERCOM Version 9 telecommunications monitor executing in the host systems as
ACF/VTAM application software.
MODEM INTERFACE COMPATIBILITY
The Government-furnished modem will present a Data Circuit-terminating Equipment (DCE)
appearance utilizing the RS-232C standard and a DB-25S EIA female connector. The terminal
control unit will present a standard Data Terminal Equipment (DTE) appearance for
full interface capability. See C.1.2.5 for Device Interconnection Requirements.
CABLES AND CONNECTORS BETWEEN CONTROLLER AND TERMINAL DEVICES
The Government shall supply and install RG62AU coaxial interface cable and BNC-type
crimp on (push and twist) male connectors (with gold pin contact preferred) to interface
the terminal devices to the control unit. The terminal devices and control unit must
be compatible with this cable and connectors. Maximum length between the control unit
and any terminal device shall be 2000 meters.
NOTE: Teflin cable must be used if the cable is to be located within a raised ceiling area.
CABLES AND CONNECTORS BETWEEN CONTROLLER AND MODEM
The vendor will supply with the controller, the cables and connection between the
controller and the Government-furnished modem. The cable will conform to Electronic
Industries Association (EIA) Standards RS-232C and be 25 feet in length. The connector
to the modem will be DB25P (male EIA). The connector at the controller shall be easy
to install by normal office personnel.
AC POWER CABLE
The vendor will supply a 9 ft. or longer power cable to a normal office type power
supply, i.e., 15 P type.
DEDICATED ELECTRICAL LINES
Each circuit will be Power Plug NEMA 5-15-P type, circuits 20 AMP HUBBEL 1G5362 or
equivalent receptacles, isolated earth grounds.
NOTE: 3rd wire grounds, true earth grounds if possible.
