IMA OPERAT ION
This chapter is a brief introduction of how a group and links are
configured, started, inhibited, deleted and so on.
6.1
IMA INITIALIZATION
ConfigDev
command is the first command to be issued to initialize
the device. If this command is not issued, the default value will be used.
6.2
CONFIGURE A GROUP
After a group is configured, an ID (IMA ID) is allocated to a physical
group, links are assigned to that group and other parameters needed for
the groups proper operation are set. The IMA ID should not be changed
during the whole life cycle of the group except that the group is
restarted.
Table-50
is the list of group parameters that should be config-
ured.
Table-50 Parameters for IMA Group Configuration
Parameter Name
Description
Group ID
The physical group ID used for this IMA group.
NE IMA ID
The IMA group logical ID#.
Mfor Tx (M
tx
)
The frame length that the NE Tx would like to use.
Acceptable Mfor Rx (M
rx
)
The frame length proposed by the FE Tx that the NE Rx can accept.
Max delay compensation value (cells)
The maximumdifferent link delay value a group is expected to have.
Version Backward Compatibility
Whether IMA 1.0 is supported
TxUtopia port
The Utopia address where ATMtraffic comes from
RxUtopia port
The Utopia address where ATMtraffic goes
Symmetry mode
The group link’s configuration and operation mode.
Timng clock mode
The transmssion timng clock mode.
Stuff mode
The SICP insertion method.
Stuff adv mode
The stuff pre-notify mode. Valid value is 1 or 4.
Timer for GSMstart up Ack
This is the timer for GSMto return fromstart-up Ack to start-up state when there is no response fromthe FE.
Timer for GSMConfigure Abort
This is the timer for GSMto return fromstart-up Abort state to start-up state.
Timer for GSMto report Rx=active
This is the timer for Group wide start-up procedure to report Rx=Active state.
Timer for GSMto report Tx=active
This is the timer for Group wide start-up procedure to report Tx=Active state.
Tx TRL
The transmt timng reference link. (Physical ID)
Alpha
The number of consecutive invalid ICP cells for the IFSMstate machine to exit SYNC state. Default value is 2.
Beta
The number of consecutive errored ICP cells for the IFSMstate machine to exit SYNC state. Default value is 2.
Gamma
The number of consecutive valid ICP cells for the IFSMstate machine to enter SYNC state. Default value is 1.
P
tx
The mnimumnumber of active Tx links for the group to enter operational state
P
rx
The mnimumnumber of active Rx links for the group to enter operational state
All the Tx links’ physical IDs
The physical links’ ID used for transmssion.
All the Tx links’ logical IDs
The logical link ID for each Tx link.
All the Rx links’ physical IDs
The physical links’ ID used for receiving.
All Tx links’ line interface Work Mode

All Rx links’ line interface Work Mode
The line interface Work Mode for each Rx link.
All Tx links’ line interface clock mode
The line interface clock mode for each Tx link.
All Rx links’ line interface Work Mode
The line interface clock mode for each Rx link.
