• With External PSTN Line Supervision
– The communication link between the alarm panel and the monitoring station is established directly
via PSTN line connected via PBX (private branch exchange) adding external PSTN state (terminals L1 and L2) supervision provided by eT083
communicator. The communicator is not involved in the communication process while PSTN connectivity is available. In case of external PSTN
loss (terminals L1 and L2), the communicator will take over the communication link and continue data transmission via the pre-configured
communication method as described in
No PSTN Line
until PSTN connectivity is restored. In case of internal PSTN loss (terminals L3 and L4),
the PSTN connectivity would remain present.
