APPENDIX B: FXO Voice/Fax Interface Module

If you are connecting to a punch block, use the
terminal block (TB1). Use a cable with bare-wire
leads (not included) to connect the terminal block
and the punch block. The terminal block is fitted
with a female plug that serves as a receptacle for the
individual cable leads.
CAUTION!
Wiring to the terminal block must be
carried out by a qualified technician.
Wires used for this purpose must be
UL type CM, 22/24 AWG, 4-conductor.
Insert each cable lead into the cutout at the front of
the plug and secure it at the top with a small flat-
head screwdriver. We recommend that you color
code the cable leads for easy identification.
Make the connection by first removing the female
plug, inserting each cable lead into the cutout on
the opening at the front of the plug, and securing it
at the top with a screwdriver (see Figure B-4).
Finally, reinsert the plug in the terminal block.
After you make the connection, install the
connector cover. To do this, simply insert the right
tab of the cover in the retaining slot of the
voice/fax interface module back panel. Then
secure on the left side with a Phillips-head screw.
