BIX block cabling for peripheral devices

Introduction
You may cable peripherals using an NEA25B cable from the appropriate
Meridian Mail I/O panel connector to the MDF as an alternative to using the 4–
and 5–port fanout cables. This is the normal method of cabling the alarm
connections.
The table below lists tip, ring, pin, and pair color information for the alarm/
modem cable and the equivalents of the 4– and 5–port fanout cables.
