This standard applies to:

a) commissioning new Ethernet transport circuits at 1G, 10G and 100G;

NOTE: The tests can be used to commission circuits on networks on a green field build or networks on a brown field build.

b) commissioning new Ethernet services at 1G, 10G and 100G line rates;

c) maintainers, if TMTH does not exist to confirm service performances when Ethernet services faults are rectified; and

d) laboratory or proof-of-concept performance threshold tests for services at 100Mbps, 1G, 10G and 100G line rates.

The standard does not cover tests for:

e) underlying cabling infrastructure;

f) individual transmission equipment;

g) network synchronisation;

h) PDH and SDH services;

i) transport circuit or Ethernet services with 10G WAN Phy; and

j) IP services.

Purpose

This document details the tests which enable Ethernet transport circuits and Ethernet services on Network Rail’s packet-based transmission networks to be commissioned uniformly and provide assurance that the services are fit for handover to operations.
