Signaling System No. 7: summary, description and annotation
We offer to read an annotation, description, summary or preface (depends on what the author of the book "Signaling System No. 7" wrote himself). If you haven't found the necessary information about the book — write in the comments, we will try to find it.
A complete, practical guide to the worlds most popular signaling system, including SIGTRAN, GSM-MAP, and Intelligent Networks.
- Provides in-depth coverage of the SS7 protocols, including implementation details
- Covers SS7 over IP (SIGTRAN) using real-world examples
- Covers SS7/C7 from both a North American and European perspective, providing a broad international understanding of the technology and associated standards
- Explains mobile wireless concepts and signaling, including mobile application part (MAP)
- Provides a thorough explanation of the Intelligent Network (IN) and associated protocols (INAP/AIN)
Signaling System No. 7 (SS7) is a signaling network and protocol that is used globally to bring telecommunications networks, both fixed-line and cellular, to life. SS7 has numerous applications and is at the very heart of telecommunications. Setting up phone calls, providing cellular roaming and messaging, and supplying converged voice and data services are only a few of the ways that SS7 is used in the communications network. SS7 also provides the point of interconnection between converging voice and data networks. This transition, which affects everyone who works with the data network, has bolstered the need for practical and applied information on SS7. In short, anyone who is interested in telecommunications should have a solid understanding of SS7.
Signaling System No. 7 (SS7/C7): Protocol, Architecture, and Services will help you understand SS7 from several perspectives. It examines the framework and architecture of SS7, as well as how it is used to provide todays telecommunications services. It also examines each level of the SS7 protocol-all the way down to the bit level of messages. In addition, the SIGTRAN standards are discussed in detail, showing the migration from SS7 to IP and explaining how SS7 information is transported over IP.

The table in this appendix summarizes Message Transfer Part (MTP) messages and the purpose of each. The signaling network management (SNM) procedures of MTP3 generate MTP messages. For an introduction to MTP3, refer to
NOTE
Messages in are marked as (ITU) or (ANSI) when they have the same encoding and meaning but different naming conventions.
H1/H0 Code | MESSAGE NAME | PURPOSE |
|---|---|---|
0 0 0 1 0 0 0 1 | COO Changeover Order | Indicates that traffic is being changed over from a primary link to an alternate link. |
0 0 1 0 0 0 0 1 | COA Changeover Acknowledgement | Acknowledgement sent in response to a COO. |
0 1 0 1 0 0 0 1 | CBD Changeback Declaration | Indicates that traffic is being changed back to a primary link from an alternate link. |
0 1 1 0 0 0 0 1 | CBA Changeback Acknowledgement | Acknowledgement sent in response to a CBD. |
0 0 0 1 0 0 1 0 | ECO Emergency Changeover Order | Indicates that traffic is being changed over from a primary link to an alternative link. This differs from a COO in that the last accepted FSN cannot be determined, resulting in possible message loss. |
0 0 1 0 0 0 1 0 | ECA Emergency Changeover Acknowledgement | Acknowledgement sent in response to an ECO. |
0 0 0 1 0 0 1 1 | RCT Routeset Congestion Test | Sent after receiving a TFC in order to test whether a routeset is at the congestion level specified by the priority of the RCT message. |
0 0 1 0 0 0 1 1 | TFC Transfer Controlled | Indicates routeset congestion for a destination. The level of congestion is indicated in the message to prevent messages of a lower priority from being sent. |
0 0 0 1 0 1 0 0 | TFP Transfer Prohibited | Sent by an STP to indicate that messages to a particular destination must be sent via another route because of a total loss of routing capability to that destination. |
0 0 1 0 0 1 0 0 | TCP Transfer Cluster Prohibited (A) | Sent by an STP to indicate that messages to a particular cluster must be sent via another route because of a total loss of routing capability to that cluster. |
0 0 1 1 0 1 0 0 | TFR Transfer Restricted | Sent by an STP to indicate that messages to a particular destination should be sent via another route, if possible, because of diminished routing capability to that destination. |
0 1 0 0 0 1 0 0 | TCR Transfer Cluster Restricted (A) | Sent by an STP to indicate that messages to a particular cluster should be sent via another route, if possible, because of diminished routing capability to that cluster. |
0 1 0 1 0 1 0 0 | TFA Transfer Allowed | Sent by an STP to indicate that messages to a particular destination can be routed normally. |
0 1 1 0 0 1 0 0 | TCA Transfer Cluster Allowed (A) | Sent by an STP to indicate that messages to a particular cluster can be routed normally. |
0 0 0 1 0 1 0 1 | RST ( ITU ) RSP ( ANSI ) Routeset Prohibited Test | Sent periodically after receiving a TFP to test whether the routeset state is still prohibited. |
0 0 1 0 0 1 0 1 | RSR Routeset Restricted Test | Sent periodically after receiving a TFR to test whether the routeset state is still restricted. |
0 0 1 1 0 1 0 1 | RCP (A) Routeset Cluster Prohibited Test | Sent periodically after receiving a TCP to test whether the routeset state for a cluster is still prohibited. |
0 1 0 0 0 1 0 1 | RCR (A) Routeset Cluster Restricted Test | Sent periodically after receiving a TCR to test whether the routeset state for a cluster is still restricted. |
0 0 0 1 0 1 1 0 | LIN Link Inhibit | A request to place a link in the inhibited state. An inhibited link cannot transmit user traffic from level 4. |
0 0 1 0 0 1 1 0 | LUN Link Uninhibit | A request to uninhibit a link that has been placed in the inhibited state. |
0 0 1 1 0 1 1 0 | LIA Link Inhibit Acknowledge | Acknowledgement sent in response to a LIN, allowing a link to be inhibited. |
0 1 0 0 0 1 1 0 | LUA Link Uninhibit Acknowledgement | Acknowledgment sent in response to a LUN. |
0 1 0 1 0 1 1 0 | LID Link Inhibit Denied | Sent in response to an LIN, denying the request to inhibit a link. |
0 1 1 0 0 1 1 0 | LFU Link Forced Uninhibit | Sent to request that a previously inhibited link be uninhibited. Used when the inhibited link is the only available route to a destination. |
0 1 1 1 0 1 1 0 | LLT ( ITU ) LLI ( ANSI ) Link Local Inhibit Test | Sent for a link in the locally inhibited state to test that the far-end link state is marked as remotely inhibited. |
1 0 0 0 0 1 1 0 | LRT ( ITU ) LRI ( ANSI ) Link Remote Inhibit Test | Sent for a link in the remote inhibited state to test that the far-end link state is marked as locally inhibited. |

0 0 1 0 0 1 1 1 | TRW Traffic Restart Waiting (A) | Sent as part of the MTP restart procedure to indicate that the sending of traffic should be delayed because of an MTP restart in progress. |
0 0 0 1 1 0 0 0 | DLC Data Link Connection | No specification. |
0 0 1 0 1 0 0 0 | CSS Connection Successful | No specification. |

0 0 0 1 1 0 1 0 | UPU User Part Unavailable | Sent to the originating signaling point when MTP cannot deliver a message to an MTP3 User. |
KEY: (A) Messages supported in ANSI only (ANSI T1.111-2000). All others supported by ANSI and ITU (Q.7041996). Note: ETSI MTP [] uses exactly the same message set and codings as ITU-T. |
[*] These messages are defined by the ITU and ANSI standards, but no specifications are stated as to their use. The authors are not aware of their actual use in existing networks.
