TMN is an abbreviation for:
The Telecommunications Management Network is a protocol model defined by ITU-T for managing open systems in a communications network. It is part of the ITU-T Recommendation series M.3000 and is based on the OSI management specifications in ITU-T Recommendation series X.700.
TMN provides a framework for achieving interconnectivity and communication across heterogeneous operations system and telecommunication networks. To achieve this, TMN defines a set of interface points for elements which perform the actual communications processing (such as a call processing switch) to be accessed by elements, such as management workstations, to monitor and control them. The standard interface allows elements from different manufacturers to be incorporated into a network under a single management control.
For communication between Operations Systems and NEs (Network Elements), it uses the Common management information protocol (CMIP) or Mediation devices when it uses Q3 interface.
Summer's coming too fast
Winter's been here too long
If we keep wasting our days
Pretty soon they'll be gone
Oh yeah, yeah, yeah
I've been out here all night
I've been out here all day
With my eyes open wide
Hoping that you will say
Everything is all right
We can be happy too
If you look out for me
The way I looked out for you
People take what they need
Then they tell you, "Get lost"
Kindly leading you on
While they're ripping you off
Oh yeah, yeah, yeah
I've been out here all night
I've been out here all day
With my eyes open wide
Hoping that you will say
Everything is all right
We can be happy too
If you look out for me
The way I looked out for you
If I sounded insecure
It's because I wasn't sure
You were really there
I've been out here all night
I've been out here all day
With my eyes open wide
Hoping that you will say
Everything is all right
We can be happy too
If you look out for me
The way I looked out for you
You can stand there all night
You can stand there all day
You can do what you like
It doesn't matter to me
