Surrogate Mode Programming

The purpose of surrogate mode programming is to allow system programming
by qualified service personnel at a service location rather than on-site. The
actual communications system hardware does not have to be installed; the
programmer needs only a direct connection from the PC to the processor
module. He or she then programs a system as if the appropriate modules,
trunks, and telephones were installed, following a customer's set of planning
forms. The programmer saves the system programming on disk by
performing a system backup. The disk is then taken to a new installation and
used (via the Restore option) to provide complete system programming for a
new communications system.
