Application
Note 1: In addition to the systems and application compatibility chart above, information at a
card and shelf level can be found in the Compatibility Section of Product Compatibility
(NN43001-256).
Note 2: It is possible for a Main Office Call Server and MG 1000B to temporarily run different
software releases, provided the Main Office is running CS 1000 Release 5.0. This allows
customers to add a single additional MG 1000B for CS 1000 Release 5.0 without having to
upgrade their entire network of MG 1000Bs.
Note 3: Mixed software configuration between a CS 1000 Release 5.0 Main Office and a CS
1000 Release 3.0 MG 1000B must be temporary.
Note 4: Mixed software configuration between a CS 1000 Release 5.0 Main Office and a CS
1000 Release 4.0/4.5 MG 1000B can be indefinite.
Note 5: In Normal mode, IP users use the feature set of the Main Office. In Local mode, IP
users use the feature set of the MG 1000B. Analog or Digital users always use the feature set of
the MG 1000B.
