NTP- D280 Add a Node to a Linear ADM Manually
Step 14
Click the
Circuits
tab and verify that no incomplete circuits appear.
Step 15
(Optional) Complete the
“NTP-D343 SNCP Acceptance Test” procedure on page 5-24
.
Stop. You have completed this procedure.
NTP-D280 Add a Node to a Linear ADM Manually
Note
Optical transmit and receive levels should be in their acceptable range as shown in the specifications
section for each card in
Note
In a linear ADM configuration, two STM-N cards in 1+1 protection are connected to two STM-N cards
in 1+1 protection on a second node. On the second node, two more STM-N cards are connected to a third
node. The third node can be connected to a fourth node, and so on, depending on the number of nodes
in the linear ADM. Slots 1 to 4 and 14 to 17 or Slots 5 to 6 and 12 to 13 can be used if connections
between nodes are consistent. For example, Slot 5 on the first linear ADM node connects to Slot 5 on
the second linear ADM node for the working path, and Slot 6 connects to Slot 6 for the protect path. The
working STM-N ports have DCC terminations, and the STM-N cards are in a 1+1 protection group.
Caution
If the linear ADM carries traffic, you cannot add a node between two linear nodes unless you delete and
recreate the circuits. Use this procedure to add a node to the end of the linear ADM.
Step 1
At the new node, complete one of the following procedures:
•
If the node has not been turned up, complete all procedures in
•
If the node has been turned up, complete the
“NTP-D35 Verify Node Turn-Up” procedure on
Step 2
Verify that the new node has two STM-N cards with the same rate as the linear ADM. If the STM-N cards
are not installed, complete the
“NTP-D16 Install STM-N Cards and Connectors” procedure on page 2-7
.
Purpose
This procedure adds a single ONS 15454 SDH node to the end of an
ONS 15454 SDH linear ADM network. If the linear ADM carries traffic,
you cannot add a node between two linear ADM nodes using this
procedure unless you delete and recreate the circuits. To avoid deleting
and recreating the circuits, use the
“NTP-D337 Add a Node to a Linear
ADM Using the Wizard” procedure on page 14-15
to add a node
between two linear ADM nodes.
