This channel protection feature along with the
skew compensation can be used to create robustness in the connection by diversely
routing channels. In this scenario, a single cable cut cannot disable the entire link.
The processes just described create a single large pipe with all the capacity available
to the clients. Priorities assigned to each client dictate the distribution of capacity, and
data clients provisioned to burst compete with each other for this bandwidth (statistical
multiplexing). The implementation of these basic functions creates a simple platform
that is easy to operate, manage, and deploy.
The deployment of point-to-point circuit-bonding solutions allows the service provider
to create new revenue from data services utilizing existing infrastructure. These
deployments are also the first step toward a modern full-featured transport platform.
The International Telecommunications Union (ITU) has passed several standards
making circuit bonding an industry standard from the bonding of optical circuits (OC3
and OC12s) to DS3 and DS1s. Additional work is being done in standardizing the service
management issues for services derived from bonded circuits.
