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 this will transfer the input of the paging amplifier
system to the transmission path of the Trunk.
