Use the Create Protection Group dialog box to create a 1:1, 1:N, 1+1, or Y-cable protection group.
|
|
|
Sets 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.

|
Identifies the protection group type. Options are:
• |
1:1 —(ONS 15454 SDH only) A working electrical card is paired with a protect electrical card of the same type. If the working card fails, the traffic from the working card switches to the protect card. |
Note |
For 1:1 protection on STM1E-12 cards, use the STM1E 1:1 FMEC. |
• |
1:N —(ONS 15454 SDH only) Allows a single card to protect up to five working cards (four for the DS3i_N-12 card) of the same electrical level. For example, an E1-42N card protects E1-42N cards. E1-42N and DS3i-N-12 cards use 1:N protection. |
• |
1+1: A working STM-N port is paired with a protect port of the same type. |
• |
Y Cable (port) —(ONS 15454 SDH only) A protection group for TXP or MXP cards that are connected to a Y-cable. The cable splits the single client signal, sending one signal to the working transponder or muxponder card, and the second signal to the protect transponder or muxponder card. A Y-cable must be connected to the cards after the protection group is created. |
• |
Splitter —(ONS 15454 SDH only) Appears automatically when a TXPP_MR_2.5G or MXPP_MR_2.5G card is installed. These cards contain two trunk ports that provide trunk-side protection in DWDM networks. |
• |
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. |

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.
|
|
Lists the cards that are available for protection.
|
|
Lists the cards that are available to be the working card.
|
|
(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.
|
|
If checked, traffic reverts to the working card after failure conditions remain corrected for the amount of time entered in the Reversion Time field.
|
|
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.
