<strong>Test</strong> <strong>Plan</strong> <strong>for</strong> <strong>Optical</strong> <strong>Grooming</strong> <strong>Switches</strong><br />
TCA060: Removal of central, critical switch matrix card.<br />
Purpose:<br />
Confirm that critical centralised switch matrix cards are 1+1 protected and can be replaced<br />
without loss of traffic<br />
<strong>Test</strong> method:<br />
1. Begin with configuration A and no circuits configured<br />
2. Break fibres PAR#7-LON#1. PAR#6-LON#2 and PAR#5-NY#3<br />
3. Set up unprotected STS-1 trail from PAR#8 to NY#6<br />
4. Confirm SONET tester is error free and that trail is routed Paris-LA-NY<br />
5. Per<strong>for</strong>m supplier specified operation to remove a central switch card in LA node<br />
6. Check management system and STS-1 traffic<br />
7. Replace card and check management system.<br />
8. Per<strong>for</strong>m supplier specified operation to reactivate card.<br />
Expected result:<br />
No loss of traffic on STS-1<br />
Within 10 seconds management system shows alarm indicating card out<br />
Any other comments:<br />
In theory the architecture may be such that there are no central, critical switch card.<br />
If so, the supplier should state this and BTexact will seek paper evidence. If BTexact<br />
are satisfied then the test will be considered passed.<br />
TCA061: <strong>Test</strong> replacement of central, critical switch matrix card<br />
Purpose:<br />
To confirm operation when central, critical switch card is replaced<br />
<strong>Test</strong> method:<br />
1. Following successful completion of TCA060<br />
2. Replace switch card<br />
Expected result:<br />
The traffic on STS-1 trail should not be affected<br />
Within 10 seconds the replaced card should be visible on management system –<br />
card status, location and available resources<br />
Any other comments:<br />
None<br />
TCA062: <strong>Test</strong> removal of network element control card<br />
Purpose:<br />
Generally there are cards within a network element which are used <strong>for</strong> management and<br />
control of the switch. Check that if removed there is no loss of traffic and an alarm is raised.<br />
<strong>Test</strong> method:<br />
1. Following successful completion of TCA061<br />
2. Remove control card from LA node<br />
