How do I connect the VISTA-128FBP to central station monitoring — what communicator options are available?

The VISTA-128FBPT connects to a central monitoring station using its built-in telephone communicator via an RJ31X jack (CA38A in Canada) (Page 69, 71) [1].

The system is designed to transmit alarm and status messages over standard telephone lines (Page 5) [1].

If the connection fails, the keypad will display "COMM. FAILURE," while a "MODEM COMM" display indicates the system is actively on-line with the central station's remote computer (Page 60) [1].

The provided manuals do not list alternative communicator options such as cellular or IP modules.
