Test Plan for Optical Grooming Switches 2. At A insert legal Tandem Connection Access Point Identifier (TC-APId) as expected by B Expected result: • No alarms/errors expected. TCA045: Test unexpected Tandem Connection Access Point Identifier. Purpose: Confirm action when unexpected TC-APId path trace is received at B. Test method: 1. Set A to “Transparent” and B to terminate the TCM bytes. 2. At A insert different TC-APId to that expected at B. 3. Check for TC-APId between A & B using testers in through mode. Expected result: • May raise alarm on management system. • Should receive path AIS (AIS-P / AU-AIS) downstream on tester at B. • B should terminate the N1 byte with “00h”and raise a remote defect indicator upstream (TC-RDI) (observed at A). TCA046: Errors with TCM section. Purpose: Confirm TCM operation – Errors with TCM section. Test method: 1. Set A to “Transparent” and B to terminate the TCM bytes. 2. Insert B3 errors at tester No. 1. Expected result: • Measure same number of B3s at B. • Measure RDI & OEI (outgoing error indication) at A from B. • Management system should indicate errors occurring within the TCM section. TCA047: Errors external to TCM section. Purpose: Confirm TCM operation – Errors external to TCM section. Test method: 1. Set A to “Transparent” and B to terminate the TCM bytes. 2. Insert IEC at tester No. 1(incoming error count) in A. Expected result: • Expect to measure same number of B3 errors at B and to record OEI back at A. • Management system should indicate errors occurring outside the TCM section. TCA048: TC-AIS external to TCM section. Purpose: Confirm TCM operation – AIS external to TCM section. Test method: 1. Set A to “Transparent” and B to terminate the TCM bytes. 2. Insert incoming AIS in the IEC into A using tester No. 1. 38
Test Plan for Optical Grooming Switches Expected result: • Expect to measure AU-AIS at B and to record ODI back at A. • Management system should indicate AIS occurring outside the TCM section. TCA049: Link test. Purpose: To check TCM source for errors Test method: • Set A and B to terminate the TCM bytes. • Terminate TCM at A and B • Insert B3 errors in A, using tester No.1. Expected result: • Expect to measure same number at B using tester No. 4. • The inserted TC-APId, number ofB3 errors and IEC of the TCM source can be verified with tester No. 2. • The B3 errors measured at tester No. 4 must agree with B3 errors transmitted by tester No. 1 and with the B3 and IEC errors measured at tester No. 2. • The N byte is terminated at B. • Management system should indicate errors occurring outside the TCM section.

TCA53 to TCA57 Test Block description: Investigate Transparency of vendors system to SONET / SDH overhead bytes. Procedure: Block of test to be proceeded in sequence from TCA50 to TCA54. Test equipment needed: Four SONET/SDH test sets. Switch management system. Computer running Exact Test software interfacing to testers. Test equipment placement and set-up: A SONET/SDH protocol tester to monitor traffic at Port A. • Clock from received optical • Optical OC-48 A SONET/SDH protocol tester to monitor traffic at Port B. • Clock from received optical. • Optical OC-48 A SONET/SDH protocol tester to through-mode within main trunk in direction between Port A and Port B • Clock from received data. • Through mode. • Out of service, transparent. 39
