Paging connection
The figure shows how to connect the paging equipment Ericall Contactor with 2 wire speech. The PBX sends paging
information to paging system (pin 6A18) using M1 contact, and information about ’paging in progress’ or ’paging
equipment not present’ is received on the E1-wire (pin 6C18) from the paging equipment.
Applies for switches 109, 209, 309 and 409.
