Configuring Redundancy Through the Distribution Bus

Redundancy by way of the distribution bus applies to T1 channels you linked for bulk distribution. For a redundancy configuration on the MGX-SRM-3T3/B that utilizes the distribution bus:

•

•

•

No back cards are necessary.

The MGX-SRM-3T3/B can support multiple switchovers for different 1: N redundancy groups.

Slots 9, 10, 15, or 26 are not supported.

Before you specify redundancy with bulk distribution, linkage must exist between a T3 line on the MGX-SRM-3T3/B and a primary service module with the T1 lines. No linkage should exist on the secondary service module. To configure redundancy through the CLI:

Step 1 Execute addred on the active PXM:

addred <redPrimarySlotNum> <redSecondarySlotNum> <RedType>

where:

redPrimarySlotNum

is slot number of the slot containing the primary card.

 

Permissible slot numbers are in the range 1–6, 11–14,

 

17–22, and 27–30.

redSecondarySlotNum

is slot number of the slot containing the secondary card of

 

the card pair. Permissible slot numbers are in the range

 

1–6, 11–14, 17–22, and 27–30.

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.

Bit Error Rate Testing Through an MGX-SRM-3T3

The MGX 8850 switch can perform a bit error rate test (BERT) on an active line or port. This type of testing disrupts service because a BERT session requires the tested path to be in loopback mode. In addition, the pattern test replaces user-data in the path with the test pattern. The applicable line types and variations for a DS1 are:

•

•

•

•

A T1 or E1 line

Fractional portions of a T1 line that add up to a DS1

A single 56-Kbps or 64-Kbps DS0

A DS0 bundle consisting of N x 64-Kbps DS0s

With a set of MGX-SRM-3T3/B cards in the system, you can initiate a BERT session on an MGX-FRSM-2CT3 or any eight-port service module. (In contrast, the MGX-FRSM-2T3E3, MGX-CESM-T3, and MGX-CESM-E3 do not use the MGX-SRM-3T3/B for BERT. See the sections for these service modules in this chapter for applicable BERT.)
