Typical Transport Evolution

• For Hybrid backhaul, Enhanced-Hybrid solution provides low delay and lowcost for TDM service, and higher efficiency for IP services.

• In later stages, when most services are IP-based and the number of TDM

services is low, running in Pure-Packet mode reduces OPEX unifying

Synchronization Standards and Protocols




Definition

Synchronous Ethernet is a technology of frequency synchronization at the

physical layer. It extracts clock signals from serial bit streams on an

Ethernet line, and transmits the data through the extracted clock signals to

implement the transfer of clock signals. OptiX RTN 900s form a

synchronous Ethernet

Standards and protocols associated:

•ITU-T G.8261: Timing and Synchronization aspects in Packet Networks

•ITU-T G.8262: Timing characteristics of synchronous Ethernet equipment

slave clock

Synchronous Ethernet

Purpose

With the IEEE 1588 ACR technology applied on a

transport network, the clock frequency is carried in an

IEEE 1588v2 packet, which traverses an asynchronous

PSN; as a result, the clock frequency of the equipment

at the two ends of the PSN is synchronized.

Standards and protocols associated:

•ITU-T G.8261/Y.1361
