Here you will find documentation for the following SIGTRAN Signalling User
Adaptation Layers and related SS7 over IP information.
Signalling User Adaptation Layers and protocol layers intended to run over
Stream Control Transmission Protocol (SCTP)
[RFC 2960]
and provide adaptation between SCTP and a signalling protocol such as ISDN.
Current Signalling User Adaptation Layers for which drafts or RFCs exist are
as follows (click 'em):
- SCTP - Stream Control Transmission Protocol
SCTP is an IP transport designed for transporting signalling
information over an IP network. This is a collection of RFCs and
Intenet-Drafts for SCTP.
SCTP is an integral part of the OpenSS7 SIGTRAN stack. OpenSS7 also has several
implementations of SCTP that are independent of the
SIGTRAN stack.
- UA - Common User Adaptation Layer Documentation
This is a collection of Internet-Drafts and RFCs that apply to several
or all the Signaling User Adaptation Layers. There are also UA
extension drafts here. The SCTP RFCs and drafts are also located
here.
The OpenSS7 SIGTRAN stack
implements all of the extensions listed here.
- TUA - SS7 TCAP-User Adaptation Layer
TUA is an SS7 Signalling User Adaptation Layer for providing TCAP-User
signalling over SCTP.
TUA is intended to be used on a Provider/User basis where TCAP resides
on a Signalling Gateway (SG) and TCAP Users reside on an Application
Server (AS).
TUA is an integral part of the
OpenSS7 SIGTRAN stack.
- SUA - SS7 SCCP-User Adaptation Layer
SUA is an SS7 Signalling User Adaptation Layer for providing SCCP-User
signalling over SCTP.
SUA is intended to be used on a Provider/User basis where SCCP resides
on a Signalling Gateway (SG) and SCCP Users reside on an Application
Server (AS).
SUA is an integral part of the
OpenSS7 SIGTRAN stack.
- ISUA - SS7 ISUP-User Adaptation Layer
ISUA is an SS7 Signalling User Adaptation Layer for providing ISUP-User
signalling over SCTP.
ISUA is intended to be used on a Provider/User basis where ISUP
resides on a Signalling Gateway (SG) and ISUP call control
applications reside on an Application Server (AS).
ISUA is an integral part of the
OpenSS7 SIGTRAN stack.
- M3UA - SS7 MTP3-User Adaptation Layer
M3UA is an SS7 Signalling User Adaptation Layer for providing MTP-User
signalling over SCTP.
M3UA is intented to be used on a Provider/User basis where MTP Level 3
resides on a Signalling Gateway (SG) and MTP Users reside on an
Application Server (AS).
M3UA is an integral part of the
OpenSS7 SIGTRAN stack.
- M2UA - SS7 MTP2-User Adaptation Layer
M2UA is an SS7 Signalling User Adaptation Layer for providing
Signalling Links interface over SCTP.
M2UA is intended to be used on a Provider/User basis where MTP Level 2
resides on a Signalling Gateway (SG) and MTP Level 3 resides on an
Application Server (AS). It is not intended for peer-to-peer
operation: that is, it is not intended to emulate a signalling link
between two SCTP endpoints. For peer-to-peer operation, see M2PA, below.
M2UA is an integral part of the
OpenSS7 SIGTRAN stack.
- M2PA - SS7 MTP2-User Peer-to-Peer Adaptation Layer
M2PA is an SS7 Signalling User Adaptation Layer for providing SS7
signalling links over SCTP.
M2PA is intented to be used on a Peer-to-Peer basis and replace the
functionality provided by a traditional SS7 link.
M2PA is an
OpenSS7 Network Device.
- IUA - ISDN Q.921-User Adaptation Layer
IUA is an ISDN Signalling User Adaptation Layer for providing ISDN
signalling over SCTP.
Also included here are drafts for DUA, GR303-UA, V5UA and a number of
ISDN related RFCs and Internet-Drafts.
IUA is an integral part of the
OpenSS7 SIGTRAN stack.
- TALI - Tekelec's Transport Adapter Layer Interface
TALI is Tekelec's Transport Adapter Layer Interface for providing MTP,
SCCP and ISUP signalling over TCP and SCTP.
TALI is an integral part of the
OpenSS7 SIGTRAN stack.
- SS7/IP - Miscellaneous SS7/IP
IPlink is an old draft for providing SS7 Signalling Links over UDP.
SS7/IP is an
OpenSS7 Network Device.
