The value of sdpBindApipeAdminConcatCellCount specifies
the maximum number of ATM cells to accumulate
into an MPLS packet. The remote peer will also signal the
maximum number of concatenated cells it is willing to
accept in an MPLS packet. When the lesser of (the
configured value and the signaled value) number of cells
is reached, the MPLS packet is queued for transmission
onto the pseudowire.
