Procedure 7-1 (continued)
Testing STM-1/4/16/64/OC-3/12/48/192 protection switching with traffic on 63xE1DS1 service
interface
Step Action
2 Select the type of protection required.
Daisy-chaining the E1/DS1 ports at the near end
3 Connect the Rx of the E1/DS1 port 1 to the Tx of the E1/DS1 test set and Tx
of the 63rd E1/DS1 port to the Rx of the E1/DS1 test set as shown in Figure
7-1 on page 7-6.
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 E1/DS1 ports, both at the near and far end
5 Feed E1/DS1 traffic from the test set to the first E1/DS1 port and the
remaining E1/DS1 ports are connected in tandem so that all the ports are
sourced from the same test set.
6 Loopback all the E1/DS1 ports of the far end network element. The traffic
generated at the test set will be looped back to the test set. The E1/DS1 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 E1/DS1 test set.
8 Record the data of 63xE1DS1 testing in Table 12-1 on page 12-3.
The result verifies that all the E1/DS1 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 E1/DS1 ports and the
working optical port.
SNCP/UPSR protection is required Provision the cross-connects
between the E1/DS1 ports and the
optical ports in SNCP/UPSR mode.
