NTP- D216 Create a Low-Order Path Tunnel for Port Grouping
Step 16 Verify that the tunnel you just created appears in the circuits list. Low-order tunnels are identified by
LOT in the Type column.
Stop. You have completed this procedure.
NTP-D216 Create a Low-Order Path Tunnel for Port Grouping
Step 1 Complete the “DLP-D60 Log into CTC” task on page 17-49 at an ONS 15454 SDH on the network
where you will create the tunnel. If you are already logged in, continue with Step 2.
Step 2 If you want to assign a name to the tunnel source and destination ports before you create the circuit,
complete the “DLP-D314 Assign a Name to a Port” task on page 20-7. If you want CTC to assign a name
automatically based on circuit type, node name, and sequence number, continue with Step 3.
Step 3 From the View menu, choose Go to Network View.
Step 4 Click the Circuits tab, then click Create.
Step 5 In the Circuit Creation dialog box, complete the following fields:
• Circuit Type—Choose VC_LO_PATH TUNNEL.
• For VC3 Port Grouping Only—Check this box.
Step 6 Click Next.
Step 7 Define the circuit attributes:
• Name—Assign a name to the low-order tunnel. The name can be alphanumeric and up to
48 characters (including spaces). Circuit names should be 44 characters or less if you want the
ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the
tunnel.
• Size—The default size is VC4. You cannot change this value.
• Bidirectional—This check box is automatically checked.
Three ports form one port group. For example, in one E3 or one DS3i-N-12 card, there are four port
groups:
– Ports 1 to 3 = PG1
– Ports 4 to 6 = PG2
– Ports 7 to 9 = PG3
– Ports 10 to 12 = PG4
Low-order path tunneling is performed at the VC3 level.
Purpose This procedure creates a low-order path tunnel for the E3 and DS3i-N-12
cards. Port group tunnels can be used to transport VC3 signal rates.
