J0 should remain unaltered.<br />
<strong>Test</strong> <strong>Plan</strong> <strong>for</strong> <strong>Optical</strong> <strong>Grooming</strong> <strong>Switches</strong><br />
Any other comments:<br />
If truly transparent system Section Span/Regenerator Section overhead bytes not<br />
should be altered.<br />
TCA053: Automated checks on each byte in the Regenerator and Multiplex section<br />
using test script.<br />
Purpose:<br />
Automated test script to investigate the transparency of the network equipment.<br />
<strong>Test</strong> method:<br />
1. Following on from successful completion of TCA052<br />
2. Run automated test using tool developed by BTexact to check each byte in the Section<br />
Span/Regenerator Section and Line Span/Multiplex Section, except A1, A2, J0, B1, B2,<br />
K1, K2 & H1/H2/H3 pointers 1 , recording the time at which the test was started. The tool<br />
will provide a report to indicate which bytes are sent and received correctly.<br />
Expected result:<br />
For a transparent system the SONET/SDH section overhead will remain unaltered.<br />
For a semi-transparent only a small part of the section overhead shall be processed, as clearly<br />
stated by suppliers equipment documentation.<br />
Any other comments:<br />
1 Cannot use remote control script to test these bytes. A1, A2, J0, K1 & K2 can be tested manually,<br />
separately if required. B1, B2 & AU pointers are automatically generated and so cannot be inserted<br />
arbitrarily, although B1 & B2 error handling are included as separate tests.<br />

BLOCK 10. Alarm reporting – including “flapping” alarms<br />
<strong>Test</strong> Block description:<br />
Investigating the ability of the switch management system to accurately and quickly<br />
display network events.<br />
Procedure:<br />
Blocks of tests to proceed in sequence from TCA054 to TC0XX.<br />
<strong>Test</strong> equipment needed:<br />
Four SONET/SDH test sets.<br />
Switch management system.<br />
Optomechanical with automated control.<br />
<strong>Test</strong> equipment placement and set-up:<br />
• Using set-up <strong>for</strong>m previous test block (Transparency of vendors system).<br />
TCA054: measure approximate time interval between breaking path, and GUI reporting<br />
fault and fault cleared.<br />
Purpose<br />
To measure the response time <strong>for</strong> displaying of alarms<br />
<strong>Test</strong> method:<br />
1. Insert optomechanical switch in main working trunk.<br />
