The STM protocol is a proprietary protocol used in some statistical multiplexors, such as Stat-4, Stat-8, and
Stat-24 (Part numbers MX864A, MX866A, and MX868A). The Fradswitch may be configured to link with
one of these STMs via any of its sync links to form a multichannel PAD.

The STM channels may be used as PAD channels. They may be configured as a PAD channel via the channel
configuration menu.
