The 2-line adapter has two jacks, each of which carries a single-pair line from the 2-line network interface jack. The 50-pin connector (attached to a 66-type block) carries up to 25 lines. You can connect your outside telephone lines from these (or other) network interface connectors to the control unit in many ways. The method you use to connect your outside telephone lines to the control unit depends on the type of network interface the local telephone company installs at the control unit location. The table on the next page tells you what to do next depending on the type of network interface you have.
