INVERSE MULTIPLEXING OVER ATM
Function
Start LASR procedure on one or more links. The links
involved may either be new links or existing links with a
failure/fault/inhibiting condition. TX_LINK_VEC and
RX_LINK_VEC are 32-bit vectors with the same bit mapping
as TX_PHY_VALID or RX_PHY_VALID respectively, the bits
corresponding to the new links are set to ‘1’. If the group
configuration is symmetric, the TX_LINK_VEC and
RX_LINK_VEC should be identical.
Parameters
Group Tag and vector of LIDS to be included in LASR
Pre-requisite Link records need to be properly initialized by PM prior to
issue this command. Also RDAT/TIMA needs to be initialized
properly to reflect the new links, if any.
Restriction
This command will be rejected if there is currently an active
LASR procedure.
7. Delete_link
Function
Remove links from the group. The TX_LINK_VEC and
RX_LINK_VEC fields indicate the links to be removed. If the
group configuration is symmetric, the TX_LINK_VEC and
RX_LINK_VEC should be identical.
Parameters
Group Tag and vector of LIDS to be deleted
Pre-requisite None.
Restriction
Deletion of a TRL Link is a special case. A group will not be
able to operate normally without both the TX TRL and the RX
TRL. Therefore, the TRL link should not be deleted unless it
is the last link in the direction.
Also, IMA protocol requires there to be at least 1 link in both
directions, therefore PM should not delete the last link left in
either direction in cases other than a complete group
removal.
8. SET_RX_PHY_DEFECT
Function
Indicate to RIPP that the given link(s) have/have not physical
