Inability to patchadd P2P PVC for ADSL-IMA on MA5100 using BMS

Publication Date:  2012-07-25 Views:  58 Downloads:  0
Issue Description
When customer tries to patchadd P2P PVC and choose the PVC type as ADSL-IMA, he got an error  "Operation failed. Failure cause: The message transmitted by MDP failed."
BMS version V200R011C02B026.
Alarm Information
Operation failed. Failure cause: The message transmitted by MDP failed.
Handling Process
Enable the Narrowband service manager process, the error disappeared.
Root Cause
Because the customer is managing BroadBand products only and not managing any narrowband ones, he disabled the narrowband process. The IMA is a multiplexing E1s so it is a narrowband service not broadband, so process related to narrowband must be enabled.
Suggestions
You must know what a process is responsible for before disabling it.
