Chapter 3 Node Setup

Creating Card Protection Groups

Step 4 From the Available Cards or Available Ports list, choose the card or port that you want to be the working

card or port (the card(s) or port(s) that will be protected by the card or port selected in Protect Cards or

Protect Ports). Click the top arrow button to move each card/port to the Working Cards or Working Ports

list.

Step 5 Complete the remaining fields:

• Bidirectional switching—(optical cards only) Click if you want both the transmit and the receive

channels to switch if a failure occurs to one.

• Revertive—If checked, the ONS 15454 SDH reverts traffic to the working card or port after failure

conditions stay corrected for the amount of time entered in Reversion time.

• Reversion time—If Revertive is checked, enter the amount of time that will elapse after a failure is

corrected before the ONS 15454 SDH will revert to the working card or port.

Step 6 Click OK.

Caution Before running traffic on a protected card within a protection group, enable the ports of all protection

group cards. See the “Set Card Ports In Service” procedure on page 5-60.

Note To convert protection groups, see the “Converting E1-N14 and DS-3i-N-12 Cards From 1:1 to 1:N

Protection” section on page 7-15.

Procedure: Edit Protection Groups

Step 1 From the CTC node view, click the Provisioning > Protection tabs.

Step 2 In the Protection Groups section, choose a protection group.

Step 3 In the Selected Group section, edit the fields as appropriate:

• Name—Type a name for the protection group. The name can have up to 32 alphanumeric characters.

• Type—Choose the protection type (1:1, 1:N, or 1+1) from the pull-down menu. The protection

selected determines the cards that are available to serve as protect and working cards. For example,

if you choose 1:1 protection, only E1, E3, and DS3i cards are displayed.

• Protect Card or Port—Choose the protect card (if you are using 1:1 or 1:N) or protect port (if you

are using 1+1) from the pull-down menu.

Based on these selections, a list of available working cards or ports is displayed under Available Cards

or Available Ports.

Step 4 From the Available Cards or Available Ports list, choose the card or port that you want to be the working

card or port (that is, the card(s) or port(s) that will be protected by the card or port selected in Protect

Cards or Protect Ports). Click the top arrow button to move each card/port to the Working Cards or

Working Ports list.

Purpose Use this procedure to make changes to your card protection scheme.
