tutorial are belongs to hlc.
used this for only c&g exams.because they are based on that paraticular points for exam.
Transaction Capabilities Application Part
(TCAP)
•Facilitates
multiple concurrent dialogs between the same sub system on the same machine
using transaction IDs to differentiate.
•Used
to transport INAP in intelligent network and MAP in mobile network.
Message
Transfer Part (MTP)
•MTP
aggregates the physical and data link layer.
•Take
care of delivery a message to a final signaling point.
- But not responsible to delivery to final software application.
MTP –
1
•Physical
layer of stack.
•Provide
physical signaling connection.
MTP –
2
•Provide
link layer functionality.
Its performance,
•Framing
•Signaling
error detection, correction and retransmit.
•Error
monitoring and reporting.
•Link
flow control.
MTP –
3
•Provide
Network layer functionality.
•Node
addressing.
•Routing
and signaling unit.
•Monitor
the status of the signaling network.
•Congestion
control
•React
to failure in the signaling network.
Signaling Connection Control Part
•Used
as the transport layer for TCAP based services.
•Provides
end to end routing for TCAP message to their proper data base.
•Provides
connection less and connection.
•Provides
sub system numbers to allow message to be addressed to specific application or
sub systems at these signaling point.
MAP
•Used
to share cellular subscribers information among different networks.
•Application
layer protocol used.
INAP
•Used
to query data base for variety of functions not related to call setup and tear
down.
ISUP
•Used
in the establishment and tear down of voice and data call over the public
switched network and to manage the trunk network on which they rely.
B-ISUP
•Support
the control of voice and data communication on ATM system.
