4.0 INSTALLATION
Once the Model IM 1/F is properly configured, it is ready to install into a
PE 1090 or 1092. This section tells you how to properly connect the Model IM
1/F.
4.1 CONNECTION TO THE MODEM’S SERIAL PORT
The QuickConnect
TM
module has a 50 pin card edge connector on
one side and an RJ-45 connector on the other side. Figure 4 shows
how a QuickConnect
TM
module plugs into the back of a Patton
Electronics Model 1090 or Model 1092.
4.2
CONNECTION TO THE TWISTED PAIR INTERFACE
The Model IM 1/F supports communication between itself and a
G.703 PCM network at distances up to 4,000 feet (1219m) using 24
AWG twisted pair cable.
To function properly, the Model IM 1/F requires two twisted pairs
of metallic wire. These twisted pairs must be unconditioned, dry metal-
lic wire, between 22 and 26 AWG (0.4mm to 0.6mm diameter solid
conductors). Higher gauge wire may limit distance. Flat modular tele-
phone type cable is not acceptable.
