cords. The pin and pair assignments for the modular jacks are shown on the next page.
The rear of the panel is equipped with four RJ-21 type 50-pin jacks, designed to accommodate cables
terminated in the corresponding plug. Two screws are provided with the 180 (525-CP) and the 110 (525-AP)
connectors to secure each individual plug to the panel. The 90 (525-PA) connector is not recommended for this
