Event information generated by the SCSN online systems is sent out to people in the lab by pager. We have used Verizon paging for many years for this purpose.
Pages to Verizon users are sent by a variety of routes. We use a paging server that was developed in-house for this purpose. The four main routes that the pages take are:
-
SNPP over the Internet
-
Dial-out modem to a Verizon paging terminal
-
Packet radio to the Verizon paging center in East L.A.
-
Email to Verizon's email-to-paging gateway.
The paging software is configured to try each of these routes in order, so as to have some redundancy in case the network or phone system is unavailable after a large event.
Paging to non-Verizon users is done through the same paging server in the lab. The pages are sent by either dial-out modem or through the provider's email gateway. Currently, we send pages to users on six different paging and cell phone services. |
