E&M/DISA Trunk Cartridge wiring chart
Use the table,
Trunk Module with E&M/DISA Trunk
Cartridges,
on page 282 when a Trunk Module has only
E&M/DISA Trunk Cartridges.
If the Norstar system is being connected to another Norstar
system or private branch exchange by connecting two RJ2HX/
CA2HA distribution blocks together, use the following table
to determine the required cross-connections.

Tips -
When installing a mixture of E&M/DISA, DID, BRI,
or Loop Start Trunk Cartridges, it is important to cross-
connect the wiring for each type of TC to a separate
distribution block.
To verify the operation of the Norstar E&M cards and the
target lines, wire the two E&M lines on the Norstar E&M back
to back.
The cross-connections to each distribution block must always
begin at pins 26 and 1. To retain emergency telephone function
(when it is available on the trunk module), install a Loop Start
Trunk Cartridge in the left-most slot (slot 1) of the TM.
