6-19 MINI-LINK BAS
EN/LZB 111 0542 P2B Technical Description
The resource collector provides HHs with a function that allows these
latter to verify whether new connections are allowed or not. This of
course takes into consideration the operational and administrative
states of both the ATM interfaces and the involved boards.
There is no direct interface among HHs.
Examples of HHs are:
• ET
• Cellmux
• MINI-LINK BAS, RN and AT
• CE units
6.5.4 MRS & MRI
The interface towards the EM is handled by the Managed Resource
Interface (MRI), which is a generic Erlang language based interface
between the Managed Resource Server (MRS) on one side and the
management interfaces on the other side (Figure 6-8).
The MRS acts as a sort of “dispatcher”, by forwarding the requests
coming from the EM to the appropriate main application or the HH.
MRS does not know anything about the configuration parameters of
the equipment in the network, nor their values: it only knows which
are the currently “managed objects” and how to have access to them,
what HHs is involved and what is the relevant instance, that is which
shelf or board.
