5. Connect the other end of each RS-366 cable to the RS-366 dial
ports on the terminal adapter or other network terminating
equipment.

RS-449 Network Interface

The RS-449 channel port transmits data signals using the RS-422
balanced line data transmission standard. This interface operates at
the following bit rates:
56 kbps through 768 kbps with ITU-T Recommendation H.320
and SG4ª
56 kbps through 768 kbps with SG3ª
You must follow these guidelines when providing the cable:
Use a Belden 9737 (or equivalent) cable
When the Concorde¥4500 is set to nondialed mode, it
F.Y.I.
F Y I
asserts TR and RS. If the DCE requires either of these
signals, that signal may have to be provided in the cable. A
larger cable, such as a Belden 9732, is then required.
Provide a cable that is no longer than 1,000 feet (450 meters)
between the system and the network at 384 kbps
Provide a DC-37 female connector to mate with the male RS-
449 connector on the back of the electronics module, as shown
in Figure 2-3
