Redundancy Support by the MGX-SRM-3T3/B

The need for back cards and the choice of bus for redundancy support depends on whether the

MGX-SRM-3T3/B must provide bulk distribution:

•With bulk distribution, the T1 service modules do not use back cards. The MGX-SRM-3T3/B uses the distribution bus to support redundancy.

•Without bulk distribution, the supported service modules must have back cards. The redundant card set requires a special redundancy back card (the R-RJ48-8T1 or R-RJ48-8E!). The primary card sets use standard back cards (RJ48-8T1 or RJ48-8E1).

With redundancy provided by the SRM, no Y-cables are necessary because the MGX-SRM-3T3/B itself passes the traffic to the redundant front card if a failure necessitates switchover. Conversely, any card with 1:1 redundancy supported by Y-cabling does not require an SRM. For example, the FRSM-VHS cards have 1:1 redundancy through a Y-cable. The MGX-SRM-3T3/B redundancy feature is particularly important for cards that do not have Y-cable redundancy—the T1 and E1 service modules.

Configuring Redundancy Through the Redundancy Bus

For redundancy that utilizes the redundancy bus, the characteristics are:

•Both the primary and the redundant front cards must have back cards. The secondary back card must be the version specifically designed to be redundant cards. Examples are the R-RJ48-8T1 and R-RJ48-8E1, where the first “R” means redundant.

•An MGX-SRM-3T3/B can redirect traffic for only one failed card at a time regardless of the number of redundant groups you have configured to rely on that MGX-SRM-3T3/B for redundancy.

To configure redundancy through the redundancy bus:

Step 1 Execute addred on the active PXM:

addred <redPrimarySlotNum> <redSecondarySlotNum> <RedType>

where:

redPrimarySlotNum

is slot number of the slot containing the primary card.

 

The slot numbers are 1–6, 9–14, 17–22, and 25–30.

redSecondarySlotNum

is slot number of the slot containing the secondary card

 

of the card pair. The ranges are 1–6, 9–14, 17–22, and

 

25–30.

RedType

is a number that specifies the type of redundancy. Enter a

 

1 to specify 1:1 redundancy. Enter a 2 to specify 1:N

 

redundancy. Only an SRM can support 1:N redundancy.

Step 2 Check the redundancy status for all cards by using dspred.

To remove redundancy, use delred.
