Study Group 15 has
consented a Recommendation that will address a key concern in the evolution to
next generation networks (NGN).
the proposed move to packet switched networks, carriers, mobile operators and
system integrators all have a need to support time-division multiplexing (TDM)
over packet networks. TDM, experts say, today forms all of the transmission
network and a good part of the access network.
role of this Rec - G.8261 - is to outline the requirements for the support of a
crucial part of TDM's operation in packet networks. The Recommendation's
authors say that without proper synchronization, applications such as mobile
telephony simply will not work.
G.8261 analyses synchronization aspects in packet networks, with
particular focus on the Ethernet, and outlines the minimum requirements for the
synchronization function of network elements. In particular it focuses on the
transport of synchronization information required for the transport of TDM
signals over packet networks. The transport of SDH signals is for further
