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 Table 2-4 on page 2-17.
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 Chapter 4, “Turn Up a Node.”
• If the node has been turned up, complete the “NTP-D35 Verify Node Turn-Up” procedure on
page 5-2.
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.
