There are two operation modes: Ring signal and Paging port modes. Select one of the two modes when using this module.
The operation method differs depending on the set operation mode. (Refer to p. 30 "Zone Paging.")

[Requirements of the PABX to be connected to the
•The PABX shall be complaint with
•Specifications or conditions required in each of the following modes shall be satisfied:
Note: The
(A)When using the module in the Paging port mode
•Connection: Line level paging port
•Signaling method: DTMF (The module cannot be operated with dial pulse.)
•Shall provide
•Insensitive to whether loop voltage exists or not, and whether polarity of the loop voltage is reversed or not when a line connection is established.
Note
If the PABX does not meet the above requirements, use the
(B)When using the module in the Ring signal mode
•Connection: Analog
•Signaling method: DTMF (The module cannot be operated with dial pulse.)
•Reorder tone: 120 IPM (impulses per minute) or less
•Loop voltage: 24 VDC or more (polarity insensitive)
•Insensitive to whether polarity of the loop voltage is reversed or not at a call from the PABX.*
•Loop voltage supply shall not be cut off from the beginning of a call to the reorder tone out.*
•The state of CPC (Calling Party Controlled) break or "Open Loop Disconnect" shall be reset at the PABX.*
*Note that there is no need to meet these requirements provided that the
