We have to validate if the abnormalities detected in their network may be due to wrong configuration of the links in the linkset.

Solution

Combining IP links and low-speed links in same linkset will limit bandwidth availability and scalability. Creating dedicated linksets for IP links and low-speed links also can cause load sharing issues (load sharing across more than two linksets).

-- The linkset "lsnname" has 8 links out which 6 are TDM HSL and remaining 2 links are IPLIMI. It is not a recommended configuration to have combination of two different link types in the same linkset.

This is recommended only during the migration.

Change the configuration of the linkset to have only IP links or only TDM links.

-- Each IPLIM card can contain multiple links and support up to 4000 TPS. There is currently no way to assign TPS limits associated with IPLIM cards or links as we do for IPSG and IPGW.

Due to this reason there cannot be a guaranteed bandwidth for a IPLIM link, hence it is recommended to migrate to IPSG M2PA links from IPLIMI M2PA links.
