Data Sheet
Note: The following conditions must apply for proper CI/NI operation:
In Bi-directional Mode, the same LCI and the same queue identifier QID must be
used for the ABR connection in forward and backward directions; for example, in
forward direction LCI=2 and QID=7, in backward direction LCI=2 and QID=7.
In Uni-directional Mode, LCI and QID must have the LSB inverted; for example,
in forward direction LCI=3 and QID=7, in backward direction LCI=2 and QID=6.
The LCI inversion (toggle) is activated by setting the LCI toggle bit in the
register to 1.
(LCI toggling and Queue toggling are not necessary for proper operation of
ABM-P but of preceding devices that expect the same LCI for forward and
backward direction of one connection (e.g. AOP PXB4340 and ALP PXB4350).)
