Chapter 3 Turn Up a Node
NTP-G31 Install the DWDM Dispersion Compensating Units
Note
The DWDM node type is determined by the cards that are installed. For example, if two
32DMX-O and two 32MUX-O cards are installed but no AD-xC-xx.x or AD-xB-xx.x cards are
installed, CTC considers the node a hub node. However, if one 32DMX-O and one 32MUX-O
card are installed with no AD-xC-xx.x or AD-xB-xx.x cards, CTC considers the node a terminal
node. For more information, refer to
Step 8
Repeat Steps
through
until all the DWDM cards are installed in the node.
Step 9
If OPT-PRE cards are installed, complete one of the following steps for each OPT-PRE card based upon
the Cisco MetroPlanner shelf layout. If OPT-PRE cards are not installed, you have completed this
procedure.
•
If the Cisco MetroPlanner shelf layout does not include DCUs, install a 4-dB attenuator with a
tolerance of +/–1 dB between the OPT-PRE DC TX and RX ports for each OPT-PRE installed in the
shelf.
•
If the shelf layout includes DCUs, complete the
“NTP-G31 Install the DWDM Dispersion
Compensating Units” procedure on page 3-41
for each side of the shelf that requires a DCU.
Stop. You have completed this procedure.
