12.1 Connecting 2-wire equipment
When connecting 2-wire equipment the following functions should be taken into
consideration:
• Auto-null
Note: Every time equipment is changed on a 2-wire port you should auto-
null.
• Enable/Disable the partyline power
• Line Termination.
These functions can be found in the 2-wire port settings page of the CCM. Navigate
to Device > A/B on any unit in the Link-Group and click ‘+’ to expand options.
