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.
You do not select surrogate mode programming; you enter it automatically,
under the following conditions:
The PC is connected to the lower RS-232 port on a control unit (direct
local connection).
Only the processor and power modules are connected.
Once you enter surrogate mode programming, the normal sequence of
procedures is as follows:
1. At the service location:
a. System Erase
b. Boards
c. System Programming
d. Backup
2. On-site:
a. Restore
While you are in surrogate mode, Pass-Thru and Password are unavailable to
other users. For more information, see "Boards" later in this chapter.
