What does PSTN mean?
PSTN refers to the Public Switched Telephone Network, the legacy
standard that made telephone service nearly universal over the
last hundred years. The PSTN is based on analog telephone sets
with copper wire circuits that are switched to connect phones
together. TDM trunk lines are also considered part of the PSTN.
How does managed security
Companies that specialize in network security install VPNs and
managed firewalls that they remotely monitor from a network operations
center. A dedicated security team that specializes in knowing
what threats are out there, when they are coming for your network
and what to do to mitigate the threat provides the vigilance for
a multitude of clients.
