<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 />
