The protocol converter emulates an IBM cluster controller and can access a
variety of IBM applications. ASCII terminals can now be connected to the
IBM link using standard telephone twisted pair cable. The ASCII terminals
may be located up to 4000 cable feet from the Meridian 1 or dialed in through
a modem pool. The protocol converter may also be located 4000 cable feet
from the Meridian 1 and a maximum of 50 cable feet from the IBM host for
direct connections or unlimited with modem pairs.
This makes moves and changes less costly and the IBM user may now benefit
from the added features of Ring Again, Auto Dial, Speed Calling, and other
data call processing features.
The Meridian 1 Protocol Converter is 12 in (305 mm) long, 14 in (356 mm)
wide, 4.5 in (115 mm) high and weighs 8 lb (3.6 kg). It operates in an office
environment of 26°F to 91°F (10°C to 35°C) with a 20 to 80% relative
humidity. It requires a 110 V ac, 60 Hz, 1 amp circuit. It can be mounted in
the MCDS cabinet, in a standard EIA 19 inch rack or may be ordered as a
desk-top module. It is connected to the Meridian 1 through an AILC.
The converter provides asynchronous ports for eight logical units: seven
asynchronous ports and one dynamic printer port. A logical unit is assigned
to each of the seven physical asynchronous connections. The eighth logical
unit is a printer port that can be dynamically assigned to auxiliary ports
associated with CRT connected to the seven asynchronous physical ports.
The ports operate at speeds of 300, 600, 1200, 2400, 4800, or 9600 bps.
The converter provides one synchronous, full duplex/half duplex port that
supports direct FEP connection (built-in modem eliminators) or remote
connection via dedicated or dial up modems. This port provides clocking
speeds of 1200, 2400, 4800, or 9600 bps and multi-drop configuration over
private lines.
