local manager:
• Passes only the NC commands that are addressed to a
remote modem from its NC IN port to the in-band
secondary channel
• Passes only responses that are addressed from a
remote modem to the local manager from the

A remote modem receiving the local modem’s
commands does not pass them to its NC OUT port.
