Class 4 service A connection-oriented service that allows fractional parts of the bandwidth to be used in a virtual circuit. Class 6 service A connection-oriented multicast service geared toward video broadcasts between a central server and clients.

Includes acknowledgement of data delivery or nondelivery. class of A specified set of delivery characteristics and attributes for frame delivery. service CLI Command-line interface.
