Last Updated :

1. MTP3 :
This Message Transfer Part (MTP3) is an Part of the Signaling System And it is used for Communication in Public Switching (Communication)Telephone Networks
- Message Transfer Part Level 3 (MTP3) is an that Resides at the OSI Model At Layer 3
- This MTP3 Protocol Performs the SS7 protocol’s Networks functions
- MTP3 is an SS7 Level Protocol
- The MTP3 is For Signalling Data Link functional level for the narrowband signalling(Communication ) Networking links And For to Broadband The Signalling links
- MTP3 Protocol is responsible for the Reliable , Unduplicated and for the in-sequence Transport of SS7 Level Protocol Networking Messages Between to its Communication Partners
- MTP3 is formally defined primarily in ITU-T Recommendations for it
- These ITU-T tests are used to validate the correct implementation of the MTP3 protocol
- MTP3 Uses in 3G cellular networks
2. MTP3B :
The Message Transfer Part level 3 (MTP3B) Broadband provides the Message Routing discrimination and the distribution ( for peer to peer link )
- MTP3B is used for Broadband signaling
- It also provides the Signalling link management and load sharing
- Using This MTP3B Protocol Can Achieve The changeover between links within one link Set
- This MTP3B protocol is a broadband ISDN based protocol used typically in the System Modes Like ATM ( Asynchronous Transfer Mode )
- MTP3B Protocol is Having Three Sub Layer SSCF, SSCOP, and AAL5
- MTP3B Uses in Radio Access
