Applying T1 Labels to Protection Blocks
The installation kit includes red labels that you can apply to the protection blocks to identify
blocks that protect T1 circuits. These labels alert technicians to the potential presence of
powered T1 lines at a protection block.
Each 50-pair block protects two slots in the C7 shelf and has two factory labels (covering
dead pair positions 25 and 50) that identify which C7 slots are protected by that block. For
any C7 slots that will contain a T1 card, apply a red T1 label over the factory label on the
protection block.
The protection blocks are located in the splice compartment (for standard configurations) or
in the rear compartment (for cross-connect configurations).
To apply T1 labels to protection blocks
1.
Get the sheet of red T1 labels from the installation kit.
2.
In the front compartment, identify which C7 slot(s) will contain a T1 card.
3. In the splice or rear compartment, locate the protection block(s) that protect the
identified slot(s). Find the factory label for the half of the block that protects the
identified slot.
4. Apply the appropriately-numbered red T1 label over the factory label on the identified
protection block.
