BER test
Overview
This test proves the transmission quality of the link by monitoring one VC channel over a
longer period of time.
Estimated duration
Preparation time: 5 minutes, test duration: 1 hour.
Test setup
The figure below shows a possible test setup:
Remark:
ode A is expected to be a 1645 AMC node.
Procedure
Proceed as follows to perform a BER test:

pattern.
...................................................................................................................................................................................................
2
Make on node A a bi-directional VC-12 cross-connection from TP1.1 to LP1.x,q (x =
physical port, q = VC-4 number).
...................................................................................................................................................................................................
3
Make on node B a bi-directional VC-12 cross-connection from LPy.1,q to a 2 Mbit/s port.
Provision an outloop on this 2 Mbit/s port.
...................................................................................................................................................................................................
4
Start a bit error performance test for 1 hour.
...................................................................................................................................................................................................
5
Verify that the requirement mentioned below is met.
