3. SDH/SONET analyzer
The required transmission rate depends on the optical circuit packs used within the
ring. The optical circuit pack with the lowest transmission rate determines the
transmission rate which should be used for the test. For example, if OP2G5, OP10
and OP40 circuit packs are used, an STM-16/OC-48 transmission signal is required.
4. ESD Wrist Strap.
Prerequisites
Prior to performing this task, you must have done the following:
1. Set up the 2-fiber MS-SPRing/BLSR test (see section
2. Logged in to
WaveStar
®
CIT as Super User (see chapter 5, section
) if
WaveStar
®
CIT User Login has been
enabled during
WaveStar
®
CIT installation.
Automatic ring switching
Proceed as follows to test the automatic MS-SPRing/BLSR ring switching:
.................................................................................................................................................................................................
1
Start a signal transmission via the SDH/SONET analyzer.
Result:
No bit errors are present.
.................................................................................................................................................................................................
2
Remove the fiber connection between NE-A and NE-B.
Result:
An immediate switch to the “Protection” path is caused (a short traffic
interruption of about 15 ms can be observed)
.................................................................................................................................................................................................
3
Connect the
WaveStar
®
CIT PC to NE-A and perform an NE login as described in
chapter 7, section
.................................................................................................................................................................................................
