Contact the telephone company at least three weeks before the actual
installation to order the required blocks.
Complete the CA-71A or RJ-71C Block Identification Forms (Table 5 and
Table 6) for the telephone installer. The form shows the telephone installer
how the telephone lines connect to the BIX/Punch Down Blocks.
Install all BIX Blocks as close as possible to the NSL unit to which they
connect.
Plug the 2012 NSL Relay Board into the NSL unit's backplane board.
Connect the 50-pin amphenol connector on the BIX block to the 2012
relay card using the 9106 cable.
Connect the CA-71A BIX Block or RJ-71C Punch Down Block Wiring
Configuration.
See the warranty section on page 113 and provide the following
information to the telephone company:
• Telephone numbers of the lines to which the TX3 system will be
connected.
• The Industry Canada registration number for Canada or the FCC
registration number for U.S.A.
• The Ringer Equivalence Number (REN) of the TX3 system.
RJ-71C wiring configuration is not recognized by all telephone
companies. For Bell Canada who has jurisdiction for Ontario and
Quebec, refer to CA-71A block for interconnect to the telephone
entry systems.
Since there are two types of block wiring configuration, CA-71A
and RJ-71C, Mircom recommends that you contact the telephone
company as to what block wiring configuration is available. We
suggest using Mircom's standard 9106 cable for CA-71A or RJ-71C
configured blocks since they are straightforward and easy to use.
