Procedure 7-3 (continued)
Testing STM-1/4/16/64/OC-3/12/48/192 protection switching with traffic on 6xE3DS3 service
interface
Action
Step Action
1 Connect the test equipment, the near end 6200, and the far end 6200 network
elements as shown in the Figure 7-3 on page 7-16.
2 Select the type of protection required.
Daisy-chaining the E3/DS3 ports at the near end
3 Connect the Rx of the E3
/DS3 port 1 to the Tx of the E3/DS3 test set and Tx
of the 6
th
E3/DS3 port to the Rx of the E3/DS3 test set as shown in Figure 7-3
on page 7-16.
4 Connect the other consecutive ports in tandem, that is connecting the Tx of
one port to the Rx of the following port of the same interface.
Testing all the E3/DS3 ports in the 6xE3DS3 service interface, both at the near and far end
5 Feed E3/DS3 traffic from the test set to the first E3/DS3 port and the
remaining E3/DS3 ports are connected in tandem so that all the ports are
sourced from the same test set.
6 Loopback all the E3/DS3 ports of the far end network element. The traffic
generated at the test set will be looped back to the test set. The E3/DS3 ports
of the near and far end are connected through the optical ports which will
transport the signal generated by the test set.
7 Verify ‘0’ bit errors at the E3/DS3 test set.
8 Record the data in Table 12-3 on page 12-6.
The result verifies that all the E3/DS3 ports function correctly.
If Then
1+1 MSP/APS is required Provision 1+1 MSP/APS group on
the optical port, both at the near and
far end network elements.
Provision the cross- connects
between the E3/DS3 ports and the
working optical port.
SNCP/UPSR is required Provision the cross-connects
between the E3/DS3 ports and the
optical ports in SNCP/UPSR mode.
