When used in the Paging mode the trunk circuit is connected to a
customer-provided paging amplifier system. When the trunk is accessed by
dial up or attendant key operation, it provides a loop closure across control
leads A and B. In a typical application, it transfers the input of the paging
amplifier system to the transmission path of the Trunk.
