SendSeqNo for VRU ICM interface

SendSeqNo for VRU ICM interface

SendSeqNo for VRU ICM interface

Hoping somebody can clarify how the sequence number is incremented during an active dialogue between the VRU and the PG.  It is my understanding the sequence number is incremented by one for each message between the two systems. So, for example,

·VRU sends REQUEST_INSTRUCION with a sequence of 1 to the PG.
·The PG will send a RUN_SCRIPT_REQ with a sequence of 2 to the VRU.
·The VRU will then send RUN_SCRIPT_RESULT with a sequence of 3 to the PG.
....and so forth.  

So BOTH the VRU and the PG need to increment the sequence number by 1 for each exchange.  Is this the correct usage for this interface?  
A Cisco tech in the UK informed me it is the VRU that controls the sequence number increments but I can't find this anywhere in the VRU ICM interface specs.  



RE: SendSeqNo for VRU ICM interface

I just wanted to add that the VRU runs under the ICM spec for version 4.1.3.
