Paging trunk operation

When used in the paging mode, a trunk is connected to a customer-provided paging amplifier system (not zone selectable). When the trunk is accessed by dial-up or attendant-key operation, it provides a loop closure across control leads PG and A. See Figure 153 on page 654. In a typical application, this transfers the input of the paging amplifier system to the transmission path of the trunk.
