MINI-LINK BAS 3-6
Technical Description EN/LZB 111 0542 P2B
3.2.3 Generic MINI-LINK BAS Network
The generic MINI-LINK BAS network is made of several SN.
Each SN can be seen as a totally independent, tree-structured sub-
network, having the direct access to each backbone network and
offering end-user services.
The SNs are mutually independent, that is, there is no traffic crossing
the SN boundaries toward another SN without passing through the
backbone network. Each CP can manage a number of different System
Nodes (SNs). The numbers of SNs each CP can manage is mainly
dependent on the total number of ATs.
A single EM can manage up to 10 CPs. In the management
perspective the CP is the agent whilst the EM is the manager. The sub-
network controlled by the CP is therefore referred as NE.
A single CP can control up to 30 SNs. However, in order to optimise
the control architecture performance, it is recommended not to exceed
128 ATs per CP; therefore, the real number of CP to be deployed
strictly depends on the topology of each SN, and less than 30 SNs
could be actually allowed under the same CP.
