4.6 Multi-Channel Interfaces

4.6.1 RS-449 / RS-423 Model MC1
This interface includes two physical connectors. The RS-449 / 422 uses a 37-pin,
female D-Type connector and the RS-423 uses a 25-pin, female D-Type connector.
A typical application for this interface is to transport data and dialer information
from a video location to the network equipment over fiber optic cable. The RS-449
interface can carry the Video Codec data with the control lead used for call set up.
The RS-423 interface can carry either serial RS-232 data or parallel RS-366A data
for the dialing equipment, when used with the appropriate RS-366A adapter (2240-
366-ACE or 2240-366-DTE) or equivalent cables.
Table 4-G delineates the adapter wiring necessary to utilize the RS-423 for both the
DTE (Data Terminal Equipment) and ACE (Automatic Calling Equipment) ends.
