Appendix D: Channel Wiring for Eventide Analog
Input Boards
All NexLog Recorders that are equipped to record analog telephone calls (POTS)
are furnished with one or more Eventide analog input boards. Eventide provides
8-, 16-, and 24-channel analog input boards. New boards of any channel count
will contain standard pin-outs on the Telco connector. Very old 8- and 16-
channel boards may feature reverse pin-outs on the Telco connector.
All boards are labeled with the number of channels and pin-out type (either
standard or reverse), except for very early versions of the 16-channel board. If
you have one of these unlabeled Eventide analog boards in your recorder, it is a
16-channel board with reverse pin-outs.
For standard and reverse pin-out assignments, see
Board Standard Pin-Outs (8-, 16-, and 24-Channel Boards)
Analog Board Reverse Pin-Outs (8- and 16-Channel Boards)

The Eventide Quick Install Kits available for these boards come with cables that
compensate (if necessary) for the pin ordering so that when wiring the punch
down blocks, the lines are in order according to normal telephone company
