Figure 70 IMA Link Status Screen Configuring the T1/E1 Interface 99 The IMA Link Status screen lists the following information pertaining to the IMA status of an individual link in an IMA group. NE Tx State-The near-end transmit state in the interworking link state machine. Table 23 lists the possible link states. NE Rx State-The near-end transmit state in the interworking link state machine. Table 23 lists the possible link states. FE Tx State-The far-end transmit state in the interworking link state machine. Table 23 lists the possible link states. FE Rx State-The far-end transmit state in the interworking link state machine. Table 23 lists the possible link states. Table 23 Possible IMA Link States State not in group unusable blocked usable active Tx Condition Rx Condition This link is not part of the IMA This link is not part of the IMA group. group. This is caused by LOS, which would result in back clock from the framer if the port is in looped timing. This is caused by AFA, excessive delay, or mismatched protocol. This link is ready to pass data. This link is ready to pass data. This link is passing data. This link is passing data. NE Rx Failure-Near-end Rx failure status in the interworking link state machine. lists the possible IMA link failure status conditions. Table 24 lists the possible IMA link failure status conditions. FE Rx Failure-Far-end Rx failure status in the interworking link state machine. Table 24 lists the possible IMA link failure status conditions.
