Procedure
Proceed as follows to perform the PDH option card test:
...................................................................................................................................................................................................
1
Assign the installed option card.
...................................................................................................................................................................................................
2
If an E3 or DS3 option card is installed, then provision the TUG structure of CC1,1 to
two times TU-3.
...................................................................................................................................................................................................
3
Provision for each port of the option card tributary a cross-connection to LP1.
...................................................................................................................................................................................................

Change the default Alarm Reporting/Severity settings of the applicable NES alarm
from reported “No” to “
Yes”.
E1 option card: E12cNES (2 Mbit/s Not Expected Input Signal)
DS1 option card: E11cNES (1.5 Mbit/s Not Expected Input Signal)
E3 option card: E31cNES (34 Mbit/s Not Expected Input Signal)
DS3 option card: E32cNES (45 Mbit/s Not Expected Input Signal)
...................................................................................................................................................................................................
5
Set the PDH analyzer to the appropriate PDH bit rate (and line code) and select for 1.5
or 2 Mbit/s the 2
15 -1
PRBS pattern, for all other bit-rates the 2
23 -1
PRBS pattern.
Connect the PDH analyzer to the first option card tributary port. Start a BER test.
...................................................................................................................................................................................................
6
Monitor the analyzer for correct transmission. If a DDF is applied then check for bad
contacts of the installed cable by moving each separate cable gently (or tap on it with
your fingers) near the connector at both ends, while monitoring the analyzer for error
free transmission..
