is contained in the SYSCON database and identifies modules by their location. Each DPM is
associated with a software SNE module that appears in the list as a separate device.

All modules within the Maxum II electronic compartment have a unique identification number
as related to the software SNE module which controls them. The identification relationship
between the SNE and the modules it controls is referred to as the SNE ID String.
