2.2 DESCRIPTION
The Patton Model 1205RC synchronous modem eliminator
rack card
lets two synchronous hosts communicate with each other in
the same room for a fraction of the cost of a pair of high speed
modems. Supporting synchronous data rates of 32, 48, 56, 64, 72,
112, 128 and 144 Kbps, the Model 1205RC can be configured to emu-
late dial-up or leased line service. Maximum distance between the
connected hosts is 300 feet. Timing can be set for internal or external
clock, and all necessary data, clocking and control signals are support-
ed.
The Model 1205RC is designed to mount in Patton’s 2U high, 16-
slot rack chassis, as well as Patton’s 2/4/8-slot desktop Cluster Boxes.
This rack chassis and cluster boxes feature a switchable 120/240 VAC
power supply (optional 48 VDC) and hot swappable function/interface
cards mounted in a mid-plane architecture. Front panel LEDs show
TD, DTR and CD activity for both ports, as well as power. The rear
interface card has two UD-26 connectors for patching to the host
devices.
