Glossary
PRBS | Pseudo Random Bit Sequence. A technique used for bit error rate testing on T1/E1/J1 |
| trunks. |
Q.SAAL | Link conforming to |
RAI | Remote Alarm Indication (Yellow alarm). |
route | An MTP3 concept that determines how signaling is distributed over linksets. A route |
| consists of a destination point code and the linkset ID of one or two linksets over which |
| traffic to the destination node should be routed. When two linksets are provided, the user |
| can choose to load share traffic or treat the linksets as primary and secondary. |
s7_log | A utility that enables messages received from the protocol stack to be logged in a text |
| file. Typically used for diagnostic purposes. |
s7_mgt | A utility that performs one time protocol configuration of all protocol modules using |
| configuration parameters from the config.txt file. |
s7_play | A utility that can be used to generate messages from a text file and send them to the |
| system. Typically used for diagnostic purposes. |
SCCP | Signal Connection Control Part. An SS7 stack layer that allows a software application at |
| a specific node in an SS7 network to be addressed. |
SLS | Signaling Link Selection field. A field in the MTP3 routing label used to determine the |
| selection of an outgoing link for messages being routed to another point code. |
SS7 | Signaling System Number 7 |
SS7 Protocol Stack | A set of software modules that implement the various layers of the SS7 protocol stack. |
SS7MD | An identifier for the family of Dialogic® Multi Dimension Network Interface Boards. |
SS7MDDVR | Device driver for Dialogic® Multi Dimension Network Interface Boards. |
ssdm | A process that runs on the host interfacing with the device driver to download software |
| to the board and enable message passing to and from the board. |
STP | Signaling Transfer Point. |
system.txt | A text file used for system configuration. |
TCAP | Transaction Capabilities Application Part. An SS7 stack layer that enables the deployment |
| of intelligent network and mobile services by supporting |
| exchange between signaling points using the SCCP connectionless service. |
ttu | An example program that demonstrates how a user application can interface with the |
| TCAP protocol module. |
TUP | Telephone User Part. An SS7 stack layer that is the predecessor to ISUP (Integrated |
| Services User Part). TUP was employed for call control purposes within and between |
| national networks, both wireline and wireless. ISUP adds support for data, advanced |
| ISDN, and IN (Intelligent Networks). See also ISUP. |
upe | A worked example of exchanging messages with the MTP3 module. |
VCI | Virtual Channel Indicator |
VPI | Virtual Path Indicator |
