Prepare Carrier Loading Labels

As you connect the port CPs in each cabinet to the SIP, list the connections on the Carrier Loading label. This label is mounted on the inside of the front cover of the cabinet. (See Figure 2-29.)Keep track of –48 volt power usage so that the power supply is not overloaded.

1.Enter, the CP type under the appropriate slot number.

2.For each port, enter the terminal type and the unit load, referring to the Unit Load by Station Set Type label attached near the Carrier Loading label. (This information is also contained in Appendix C of this manual.) No port can have a unit load greater than 2.

3.When you have made entries for all- the ports of a CP, calculate the total unit load for that CP and enter the calculation in the appropriately marked square.

4.When you have made and documented all the connections for a cabinet, check the total unit load to make sure that it does not exceed the maximum of 80. (See Appendix C for more information on evaluating unit load.)
