Northern Telecom (NT) software releases are referred to as batch change
supplements (BCS) and are identified by a number, for example, BCS29.
This document is written for DMS-100 Family offices that have software
loads of BCS33 and up.
More than one version of this document may exist. The version and issue
are indicated throughout the document, for example, 01.01. The first two
digits increase by one each time the document content is changed to support
new BCS-related developments. For example, the first release of a
document is 01.01, and the next release of the document in a subsequent
BCS is 02.01. The second two digits increase by one each time a document
is revised and rereleased for the same BCS.
