Series 70 Core functions
The SuperNode and SuperNode SE components are duplicated for
reliability and operate as synchronized pairs. One plane is in-service
(active) and performs call processing and other operations. The other plane
(standby) performs the same operations, but checks for variations between

The core performs the call processing function, system management,
system sanity checking, maintenance, and loading and downloading of
programs. The core interacts with other components of the Meridian SL-100
through the MS bus, which supports multiple application modules.
