4.6.9 V.35/RS-423 Model MC2
This interface includes two physical connectors. The CCITT V.35 uses a 34-pin, female
Winchester 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 V.35 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 cabling.
Table 4-11 delineates the adapter wiring necessary to utilize the RS-423 for both the DTE (Data
Terminal Equipment) and ACE (Automatic Calling Equipment) ends.
