Paging trunk operation

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.
