Use the Edit Protection Group dialog box to edit a 1:1, 1:N, 1+1, or Y-cable protection group.
 
Item
Description
Name
The protection group name. The name can have up to 32 alphanumeric (a-z, A-Z, 0-9) characters. Special characters are permitted. For TL1 compatibility, do not use question marks (?), backslash (\), or double quote (“) characters.
Type
(Display only) Identifies the protection group type:
 •
1:1—(ONS 15454 SDH only) Pairs a working electrical card (E3-12, DS3i-N-12, STM1E-12) with a protect electrical card.
 •
1:N—(ONS 15454 SDH only) Assigns one protect card (DS3i-N-12) for several working cards.
 •
1+1—Pairs a working STM-N card/port with a protect STM-N card/port.
 •
Y Cable (port): (ONS 15454 SDH only) Pairs a working transponder or muxponder (TXP_MR_10E, MXP_2.5G_10E, TXP_MR_10G, MXP_2.5G_10G, TXP[P]_MR_2.5G, and MXP[P]_MR_2.5G) card/port with a protect transponder or muxponder card/port. A Y-cable must be connected to the cards after the protection group is created.
 •
Splitter—(ONS 15454 SDH only) Splitter protection is automatically provided with the TXPP_MR_2.5G and MXPP_MR_2.5G cards.
 •
1+1 Optimized—(ONS 15454 SDH only) A line-level protection scheme using two lines, working and protect, for the ONS 15454 SDH STM-1-4 and STM-1-8 cards. One of the two lines assumes the role of the primary channel, where traffic is selected, and the other line assumes the role of secondary channel, which protects the primary channel. Traffic switches from the primary channel to the secondary channel are based on either line conditions or a switch performed by the user. After the line condition clears, the traffic remains on the secondary channel. The secondary channel is automatically renamed as the primary channel and the former primary channel is automatically renamed as the secondary channel.
Protect Card/Port
Displays a list of cards that you can choose to be the protect card based on the protection type. If no cards are shown, no cards are available for the protection group chosen.
Available Cards/Ports
Lists the cards that are available for protection.
Working Cards/Ports
Lists the cards that are available to be the working card.
Bidirectional Switching
(1+1 protection groups only) If checked, both Tx and Rx signals switch to the protect port when a failure occurs to one signal. Leave unchecked if you want only the failed signal to switch to the protect port.
Revertive
If checked, traffic reverts to the working card after failure conditions remain corrected for the amount of time entered in the Reversion Time field.
Reversion Time
Sets the reversion time when Revertive is checked. The range is 0.5 to 12.0 minutes. The default is 5.0 minutes. Reversion time is the amount of time that will elapse before the traffic reverts to the working card after conditions causing the switch are cleared.
OK
Saves the protection group changes and closes the Protection Group dialog box.
Cancel
Cancels the protection group and closes the Protection Group dialog box.
Help
Displays context-sensitive help.
