DDTS Issue Description
CSCdv37382 The addcid command can put VISM into the fail state. If non-AAL5 cells are sent to
an AAL5 PVC of VISM, this can cause the VISM SAR chip to hang and VISM to go
into failed state. This is because, in case of AAL5, the last bit of the Payload type
indicator is used to determine which cell contains the end of that payload. All cells
which have this bit set to 0 are held in the reassembly buffer until the cell with this
bit set to 1 arrives. In case of non-AAL5 cells, this bit will never get set to 1, and
ultimately this buffer will overflow. So, care should be taken that only AAL5 cells are
sent to AAL5 PVCs of VISM.
