About This Item
Full Description
There is a requirement for the A-bis interface to be open to allow interoperation between BTSs of different manufacturers working to the same BSC. The present document addresses this requirement from O&M point of view, which allows this interworking to take place. It shows the split of NM functions between BSC and BTS. The procedures and coding of the messages are specified in detail. In practice, in addition to the present document it is necessary that the content of manufacturer-dependent information fields be specified to fulfill the functionality.
It is essential for operation that a BSC can handle the functions used by all its BTSs. Therefore, all items in the present document are considered mandatory unless otherwise indicated in the present document.
