Characteristics of a Flexible Multiplexer in a Plesiochronous Digital Hierarchy Environment - General Aspects of Digital Transmission Systems Study Group 15; 50 pp
This Recommendation gives the characteristics of a flexible multiplex equipment able to handle a variety of services with transparency for service provider, allowing enhanced management capabilities and to be used in the local network. Concentration function for switched services is not precluded and further study is necessary to cover this application. Tributaries of this multiplexer present usual interfaces related to services to which they are connected. Internal mapping functions are based on Recommendation G.704 and on 64 and n x 64 kbit/s signals. The handling of sub-64 kbit/s signals is not precluded. The equipment is intended to be installed in a Plesiochronous Digital Hierarchy (PDH) environment. Management of the equipment is in line with general principles of the Telecommunications Management Network (TMN).
