Displays the protection group type:
• |
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 Front Mount Electrical Connection (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 E1-42 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 —(ONS 15454 SDH only) A protection group for transponder or muxponder cards (TXP_MR_10G, TXP_MR_10E, TXP_MR_2.5G, MXP_2.5G_10E, MXP_2.5G_10G, MXP_2.5G_10E_C, MXP_2.5G_10E_L, MXP_MR_2.5G, MXPP_MR_2.5G, MXP_MR_10DME_L, and MXP_MR_10DME_C) that are connected to a Y-cable. The cable splits the single client signal, sending one signal to the working transponder (TXP) or muxponder (MXP) card, and the second signal to the protect transponder or muxponder card. |
• |
Splitter —(ONS 15454 SDH only) Appears automatically when a TXP or MXP card is installed. These cards contain two trunk ports that provide trunk-side protection in dense wavelength division multiplexing (DWDM) networks. |
|
|
The protection group name. If the name is not defined by the user, the protect card slot and card name appear.
|
|
The protect slot (for 1:1 and 1:N protection), or the protect card and port (for 1+1 and Y Cable protection).
|
|
The working slot, card, and port.
|
|
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.
