All SONET/SDH path alarms are configurable to be either enabled (the default) or disabled. The
MTU size is configurable per path in the range of 512 to 2092. The path uses a default MTU size
set to equal the largest possible CES packet size.
Load balancing options are not applicable to channelized CES paths.
