4.4 SNC State Representations – Modes
The member companies comprising the MTNM team have varying opinions concerning the SNC state model,
and agreement could not be reached on a single state representation model. Consequently, it was agreed to
allow four different SNC state modes:

The various modes in the above table are explained in the following subsections.
4.4.1 Mode
A
In Mode A, the goal is for the EMS to represent only the current network configuration, to limit as much as
possible sharing of resources (i.e., cross connections) among SNCs, and to attempt to have a one-to-one
correspondence between the network configurations and the SNC configurations. This mode does not support
the pending state. An SNC that does not have any non-shared, active CCs in the network is considered non-
existent. Consequently, when the last non-shared cross-connect of an SNC is deactivated in the network, the
SNC is deleted by the EMS.

In Mode A, a CC, active or not, can only belong to at most one SNC. In the case of non-singleton subnetworks,
an exception to the non-sharing rule is made for SNCs of a broadcast system, i.e., a multipoint connection. The
legs of a multipoint connection are represented as individual SNCs. The legs of a broadcast system may share
CCs and always share the same source CTP.
