the MAC address field to be unique. If data duplication appears in
the VCI information of the CMUX, it will lead to the duplication of
MAC address field in the BOOTP request package, and thus result in
the BOOTP failure and the OML establishment failure.
Solution: check the BSC configuration and make sure the data
are correct and unique.
IV.
Incorrect BSC routing information configuration
The OML of the BTS connects two IP gateways, i.e. the MPU in
the switch subrack and the CMUX in the BM subrack in the BSC,
and the uplink and downlink routing table information are different.
Error in information configuration of any of the gateways will result in
the OML establishment failure.
A typical example is that the BTS fails to establish the TCP
connection of the OML after BOOTP request is completed
successfully.
In such case, please first check the routing information of BAM
and see if it can connect to the MPU board of the switch subrack
properly; and then check the routing information of the CMUX and
see if it can connect downwards to the BTS and upwards to the BAM.
If there is an error in the routing information configuration, modify the
routing configuration of the switch subrack and the routing
information of the CMUX of BSC.
V.
Incorrect OMC data configuration
The OMC plays a role of BOOTP Server and TCP Server during
the establishment of OML. During the BOOTP process, it will first
