Secure telephone unit for PSTN

Sectéra Wireline Terminal, abbreviated SWT or WT, is a
secure interface
for existing analogue telehone equipment, developed around 2008
by General Dynamics in Needham (MA, USA) and endorsed by
the US National Security Agency (NSA) for
communication up to the level of SECRET.
It is connected between a PSTN telephone set (or fax unit)
and the subscriber line, and provides (voice) encryption using a variety of
algorithms, including AES and optionally a
Type 1 algorithm.

SWT was rolled out from 2008 onwards as an alternative for the
end-of-life (EOL)
Secure Telephone Equipment (STE),
especially in situations where analogue PSTN equipment
was used. It was declared end-of-support (EOS) by the NSA in 2019,
after it became clear that it could not be upgraded to the NSA's new
Advanced Cryptologic Capabilities (ACC) requirements [1].
As a result, support for analogue PSTN equipment
has practically disappered. Existing users were advised to move to
IP-based telephone lines and the vIPer Universal Secure Phone
as an alternative.
