2012 NSL RELAY BOARD WIRING

The 2012 NSL Relay Board plugs into the Backplane Boards of the NSL Units. There may be one to eight in each Backplane to a total of 128
per NSL Backplane. In each NSL Backplane the relay boards are numbered 1 to 8, starting from the bottom of the backplane and going to the

CA-71A BIX Block or RJ-71C Punch Down Block Wiring Configuration. The CA-71A (for Canada) and RJ-71C (for
via
U.S.A.)
Wiring Configurations of BIX or Punch Down Block are shown below. Normally, the required blocks are installed by the telephone
company. Each block serves up to 12 telephone lines. The 50 pin Amphenol connector on the BIX block is connected to the 2012 relay card
using the standard 9106 cable. Contact the telephone company at least three (3) weeks in advance before the actual installation and order the
required blocks. Complete the CA-71A or RJ-71C Block Identification Form (on page 33) for the phone installer. The form instructs the phone
installer as to how the phone lines should be wired to the BIX/Punch Down Blocks. All BIX Blocks should be installed as close as possible to the
NSL Unit to which they connect.
The following information must be given to the Telephone Company:
1. Telephone numbers of the lines to which the TAS-2000 System will be connected.
2. The Industry Canada Registration Number for Canada.
3. The FCC Registration Number for U.S.A.
3. The Ringer Equivalence Number (REN) of the TAS-2000 System.
Note: 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.
Important notice:
Since there are two types of block wiring configuration, CA-71A and RJ-71C, we recommend the user 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 straight forward and easy to use.
