INSTALLING SINGLE LINE TELEPHONES
Single Line Extension Cabling (Figure 3-2)
Each single line extension requires one-pair twisted station cable from the MDF to the modular jack. A max-
imum of 24 2-wire extensions can be installed per 50-pin 66 block.
To connect station cabling:
1. Punch down one pair 24 AWG station cable for each single line telephone to a cross-connect block.
2. Punch down cross-connect from the clips on the cross-connect block to their corresponding clips on
the extension (B) block.
3. Connect the extension (B) block's 25-pair cable to the corresponding RJ-61 connector on the PCB.
4. Install bridging clips on the extension (B) block.
Installing a Single Line Telephone (Figure 3-2)
To install a single line telephone:
1. Install a modular jack for each single line telephone. The modular jack should be within six feet of
the phone.
2. For each extension, run one-pair 24 AWG station cable from the cross-connect block to a modular
jack.
3. Terminate the extension leads to GRN/RED of the modular jack. Terminate the unused leads to the
