Security issues when connecting internal networks to public phone
lines
The product can send and receive fax data over telephone lines that conform to public switch telephone
network (PSTN) standards. The secure fax protocols make it impossible for computer viruses to be
transferred from the telephone line to a computer or network.
The following product features prevent virus transmission:
●
No direct connection exists between the fax line and any devices that are connected to the USB or
Ethernet ports.
●
The internal firmware cannot be modified through the fax connection.
●
All fax communications go through the fax subsystem, which does not use Internet data-exchange
protocols.
