Chapter 3 Node Setup
Creating Protection Groups
Procedure: Create Protection Groups for Optical Cards
Step 1
From the CTC node view, click the Provisioning tab.
Step 2
Click the Protection subtab.
Step 3 Under Protection Groups, click Create .
Step 4
In the Create Protection Group dialog box ( Figure 3-2 ), enter the following:
• Name —Type a name for the protection group, up to 32 alphanumeric characters.
•
Type —Choose 1+1 as the protection type. The protection selected determines the ports that are
available to serve as protect and working ports.
•
Protect Entity —Choose protect port from the list. Because 1:1 protection is pre-provisioned, no
XTC cards or MICs appear under available cards.
Based on these selections, a list of available working ports displays under Available Entities.

Step 5 From the Available Entities list, choose the port that you want to provision as the working port. This port
will be protected by the port you selected in Protect Entity. Select the top arrow button to move it to the
Working Entities list. You cannot move more than one port.
Step 6
Complete the remaining fields:
•
Bidirectional switching —(optical cards only) if checked, both transmit and receive channels switch
if a failure occurs to one.
Table 3-3 Protection Types
Type Cards Description
1:1 XTC Default and only available protection for electrical circuits (cannot be
changed).
1+1 Any optical Pairs a working optical port with a protect optical port. Protect ports
must match the working ports. For example, Port 1 of an OC-3 card can
only be protected by Port 1 of another OC-3 card. Cards do not need to
be in adjoining slots.
Unprotected Any Unprotected cards can cause signal loss if a card fails or incurs a signal
error. However, because no card slots are reserved for protection,
unprotected schemes maximize the service available for use on the ONS
15327. Unprotected is the default protection type.
