Support
BIP.1
Does the implementation support a number N (1
≤ N ≤ 32) of
transmission links within an IMA group operating at the same
nominal link cell rate (LCR)?
M
(R-1)
Yes X No__
1
≤ N ≤ 8
BIP.2
Does the implementation support the IMA interface connected to
another interface over clear channel facilities (implies cells
generated by transmit IMA shall only be terminated at the receive
IMA)?
M
(R-2)
Yes X No__
BIP.3
Does the interface specific TC sublayer of the implementation pass
all cells to the IMA sublayer or provide an indication that a cell was
received (this includes HEC errored cells)?
M
(R-3)
Yes X No__
BIP.4
Does the implementation prohibit cell rate decoupling at the
interface specific TC sublayer?
M
(R-4)
Yes X No__
BIP.5
Does the implementation assign a LID unique within the IMA
group to each Tx IMA link on each physical link?
M
(R-5)
Yes X No__
BIP.6
Does the implementation ensure that the LID does not change
while the link is a member of the IMA group?
M
(R-6)
Yes X No__
BIP.7
Does the implementation distribute ATM cells arriving from the
ATM layer over the N links in a cyclic round-robin fashion, and on a
cell-by-cell basis?
M
(R-7)
Yes X No__
BIP.8
Does the implementation distribute ATM cells over the links using
an ascending order based on the LID assigned to each link within
the IMA group?
M
(R-8)
Yes X No__
BIP.9
Does the implementation support the ICP cell format defined in
Table 2 on page 31 to convey IMA configuration, synchronization,
status, and defect information to the far-end?
M
(R-9)
Yes X No__
BIP.10
Does the implementation perform cell rate decoupling by inserting
IMA Filler cells in place of ATM cells when there is no cell available
at the ATM layer?
M
(R-10)
Yes X No__
BIP.11
Does the implementation accept, on receive, ATM cells from the N
links according to ascending order based on the LID received in
the ICP cells on the incoming link?
M
(R-11)
Yes X No__
BIP.12
Does the implementation, on receive, compensate for link
differential delays and rebuild the original ATM cell stream?
M
(R-11)
Yes X No__
BIP.13
Does the implementation discard received Filler cells and cells with
bad HEC?
M
(R-11)
Yes X No__
BIP.14
Does the implementation process and discard incoming ICP cells?
M
(R-11)
Yes X No__
BIP.15
Does the implementation aggregate, on receive, the ATM cell
stream to the ATM layer?
M
(R-11)
Yes X No__
BIP.16
Does the implementation preserve the order of incoming cells?
M
(R-11)
Yes X No__
BIP.17
Does the implementation use the ICP cell to maintain IMA protocol
synchronization?
M
(R-12)
Yes X No__
