Protection
Use the Protection subtab to view, create, edit, and delete node protection groups.
Displays the protection group type:
1:1: 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: 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-N-14 card protects E1-N-14 cards. E1-N-14, 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: A protection group for transponder or muxponder cards (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) 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 card.
Splitter: 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 DWDN networks.
The protection group name. If the name is not defined by the user, the protect card slot and type appear.
The protect slot (for 1:1 and 1:N), or the protect card and port (for 1+1 and Y Cable).
Indicates whether a 1+1 protection group has bidirectional switching turned on. If it is on, both transmit (Tx) and receive (Rx) signals switch to the protect port when a failure occurs to one signal.
Indicates whether the protection group is revertive, that is, whether traffic reverts to the working card or port after failure conditions remain corrected for the amount of time entered in the Reversion Time field.
The amount of time that must elapse before the traffic reverts to the working card. Traffic can revert when conditions causing the switch are cleared.
Displays the Create Protection Group dialog box to create a new protection group.
Displays the Edit Protection Group dialog box to edit the highlighted protection group.
