Type
|
Identifies the protection group type. Options are:
1:1: (ONS 15310-CL, ONS 15327, and ONS 15454 only) Pairs a working
electrical card (DS1-14, DS3-12, DS3-12E, EC-1, DS3XM) with a protect
electrical card.
1:N: (ONS 15454 only) Assigns one protect card (DS1N-14, DS3N-12,
DS3N-12E) for several working cards.
1+1: Pairs a working OC-N card/port with a protect OC-N card/port.
1+1 Optimized: (ONS 15454 only) A line-level protection scheme using two
lines, working and protect, for the OC-3-4 and OC-3-8 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.
Y Cable (port): (ONS 15454 DWDM 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 DWDM only) Splitter protection is automatically
provided with the TXPP_MR_2.5G and MXPP_MR_2.5G cards.

Cards that are available to be the working card.
|
Bidirectional Switching
|
(1+1 groups only) If checked, both Tx and Rx signals switch to the protect port when a failure occurs to one signal. If 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.
