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...
