A type of Ethernet service that is provided with dedicated bandwidth and point-to-point
connections on an SDH, PDH, ATM, or MPLS server layer network.
A type of Ethernet service provided by SDH, PDH, ATM, or MPLS networks. This
service is carried over a shared bridge and point-to-multipoint connections.
A type of Ethernet service provided by SDH, PDH, ATM, or MPLS networks. This
service is carried over a shared bridge and point-to-point connections.

An operation to check whether the protection switching protocol functions properly. The
protection switching is not really performed.
This command exercises ring protection switching of the requested channel without
completing the actual bridge and switch. The command is issued and the responses are
checked, but no working traffic is affected.
The number of the subnet that an NE belongs to, for identifying different network
segments in a WAN. The physical ID of an NE is comprised of the NE ID and extended
ID.
The traffic that is carried over the protection channels when that capacity is not used for
the protection of working traffic. Extra traffic is not protected.
If the fault persists long enough to consider the ability of an item with a required function
to be terminated. The item may be considered as having failed; a fault has now been
detected.
A feature in which for any link specified in a ring network, the source node is provided
with certain bandwidth capacities if the data packets transmitted by the source node are
constrained by the fairness algorithm.
An algorithm designed to ensure the fair sharing of bandwidth among stations in the case
of congestion or overloading.
A failure to implement the function while the specified operations are performed. A fault
does not involve the failure caused by preventive maintenance, insufficiency of external
resources or intentional settings.

Code used to select/activate a service feature (for example, forwarding, using two or
three digit codes preceded by * or 11 or #, and which may precede subsequent digit
selection).
