2. IntroductionThe tests described in this document are designed to provide Telekom Malaysia with a confidence level that the MS1/4, MSV5 & ONU200 will perform acceptably. This platform and particular features tested are based on in-station and system tests by the vendor. All tests are to be performed on a node to node basis and require (optional) staff at the two nodes at the same time. This test plan should be read once in it’s entirely paying particular attention to the cautions and the procedures. If any procedure is not understood get a clarification before starting.

6. Optical Measurements

6.1 OPTICAL TRANSMIT AND RECEIVE

Objective : To verify that the transmit & receive power within the range state in the table below.

Procedure : Connect the optical card under test with the optical power meter. Connect the optical power to the fiber tail from remote station. Observe the value shown and record in the result table. The received optical power should be equal to the launch power plus fibre attenuation, in any case shall not exceed the limits as side :

7. Redundancy test

Objective : Verify that the following functional blocks on M S1/4 or MSV5 work in redundancy by performing swap on the functional blocks:

Result :

Functional Blocks Expected Results Pass/Fail Remarks

V5CM System remains operational

SWM64 System remains operational

SWM4M System remains operational

AM-34 System remains operational

8. Path Protection Test

Objective : To verify that all the path protection available is able to reroute if any case of interruption

on the worker side.

Procedure : The MS1/4, MSV5 & ONU200 equipment is able to manage the path protection of an

individual access unit or service unit. It is possible to perform this function between tributary access module and line module. In such a way, a service unit that is normally connected to the worker line, the path protection will work is case of interruption of the normal path with traffic routing to the protection path.

Interrupt the worker line. Check the status of the path protection at the online LMT session. Check the status of Service Units or Access Modules or Line Modules on the LMT

session. Report the result in the table below.

9. Synchronization Settings

Objective : To make sure that all the clock source feeding to the subrack is tested and configured.

Procedure : To test the clock source from SSU before connecting to the equipment. Print the result

and attached to this document. The MS1/4, MSV5 & ONU200 automatically selects the best available clock signal. By using STS, measure the clock output for 8 hours. Record the all the available clock status/setting in the table below.

Objective : To verify that all the clock source configured is able to switch each other.

Procedure : In case more than one clock sources available input to the MS1/4, MSV5 & ONU 200 test

also the automatic clock switching. This test can be done by disconnected one of the clock source, and observe the clock

status at the clock window.

Automatic Clock Switching (OK / NOT OK)

11. Check the Functional of Integrated Test Unit (Two-wire test) Objective : By means of local terminal, enable subscriber line test unit. The 2-wire test will be done
