Reviewing the Installation Method
Your system uses a different installation method for trunk/AUX connections and extensions (Figure 2-1):
●
Trunk/AUX Mod Jacks
You'll use up to 6 mod jacks for the trunk/AUX connections. Your telco normally provides trunks in
RJ-11C, RJ-14C, or RJ-25C modular jacks.
●
Extension Blocks
The system uses a 66M1-50 extension block and a second 66M1-50 cross connect block for connecting
digital and analog extensions.
