Yes Finn you are right,
Sorry I should have writen Transceiver Group and Managed object directly,
To Refresh again :
A managed Object (MO) is a representation of a part of one BTS
which is given a name :Transceiver Group (TG)
of course then we have different managed object,that represent diferent part of what we want to manage in the BTS like
central function, Concentrator, Digital Path, Timing function , transmiter, receiver, time slot, etc…
Is it the same way of working for, ALCATEL, NOKIA, etc…
