Glossary
A time division multiplex (TDM) bus that provides 1024, 2048, or 4096 time slots for exchanging voice, fax, or other network resources on a PCI (H.100) or CompactPCI (H.110) backplane. The Enterprise Computer Telephony Forum (ECTF) developed the H.100 hardware compatibility specification that defined the CT Bus, a high-performance mezzanine bus. The CT Bus works with both SCbus and Multivendor Integration Protocol (MVIP) compatible products. The ECTF implementation of the CT Bus for CompactPCI bus is called the H.110 standard.
A collective name for the DataKinetics system environment and the SS7 stack.
Intel® Dialogic Configuration Manager. A Windows application the enables the configuration of Intel® Dialogic products.
The software and libraries that implement Global Call on SS7.
Destination Point Code. Identifies the address (point code) of the SS7 network node to which a Message Signal Unit (MSU) should be directed.
A generic term for an Intel® Dialogic network interface card, such as, D/300SC-E1, D/240SC-T1, DTI/300SC-E1, etc.
A digital transmission link that carries information at the rate of 2,048 Mbps. This is the rate used by European carriers to transmit thirty 64 Kbps digital channels for voice or data calls, plus one 64 Kbps channel for signaling, and one 64 Kbps channel for framing (synchronization) and maintenance.
Inter Process Communication. In a DataKinetics environment, IPC refers to the method by which modules communicate with each other using messages.
ISDN User Part. A layer in the SS7 protocol stack. Defines the messages and protocol used in the establishment and tear down of voice and data calls over the public switched network, and to manage the trunk network on which they rely.
Integrated Services Digital Network. A service that offers simultaneous digital data and voice communication over a single copper pair wire in residential and business phone connections. There are two basic flavors, BRI (Basic Rate Interface) which is 144 Kbps and designed for the desktop, and PRI (Primary Rate Interface) which is 1.544 Mbps and designed for telephone switches, computer telephony and voice processing systems.
Layers 1 to 3 of the SS7 protocol stack equivalent to the Physical, Data Link and Network layers in the OSI protocol stack. See also MTP 1, MTP 2 and MTP 3.
Message Transfer Part Level 1. Defines the physical and electrical characteristics of the signaling links of the SS7 network. Signaling links use DS0 channels and carry raw signaling data at a rate of 56 Kbps or 64 Kbps (56 Kbps is currently the more common implementation).
Message Transfer Part Level 2. Provides link-layer functionality. Ensures that two end points of a signaling link can reliably exchange signaling messages. It provides error checking, flow control and sequence checking.
Message Transfer Part Level 3. Provides network-layer functionality. Ensures that messages can be delivered between signaling points across the SS7 network regardless of whether the signaling points are directly connected. It provides node addressing, routing, alternate routing and congestion control.
Originating Point Code. Identifies the address (point code) of the SS7 network node from which a Message Signal Unit (MSU) originated.
Public Switched Telephony Network. The worldwide voice telephone network accessible to all those with telephones and access privileges.
An Intel® NetStructure™ SS7 ISA board solution.
The standard bus for communicating within an SCSA node. The SCbus features a hybrid bus architecture consisting of a serial message bus for control and signaling, and a 16-wire TDM data bus.
Signal Connection Control Part. A layer in the SS7 protocol stack that allows a software application at a specific node in an SS7 network to be addressed. It also supports Global Title Translation which frees an originating signaling point from having to know every possible destination to which a message may have to be routed.
Service Control Point. Databases that provide information necessary for advanced call-processing capabilities.
A signaling data link is a bidirectional transmission path for signaling, comprising two data channels operating together in opposite directions at the same data rate.
The Intel® NetStructure™ SS7 server solution.
Signaling Point. Any point in a signaling network capable of handling SS7 control messages. Examples of Signaling Points are: SSP (Signal Switching Point), STP (Signal Transfer Point), and SCP (Signal Control Point).
Signaling System Number 7. A common channel signaling standard that defines the procedures and protocols required for the connection of network elements in the Public Switched Telephone Network (PSTN).
Signal Switching Point. Telephone switches (end offices or tandems) equipped with SS7-capable software and terminating signaling links. They generally originate, terminate or switch calls.
Signal Transfer Point. A signaling point capable of routing control messages to another signaling point. STPs receive and route incoming signaling messages towards the proper destination and perform specialized routing functions.
A digital transmission link with a capacity of 1.544 Mbps (mega bits per second). T-1 uses two pairs of normal twisted wires and can handle twenty-four voice conversations, each one digitized at 64 Kbps.
Transaction Capabilities Part. A layer in the SS7 protocol stack that defines the messages and protocol used to communicate between applications (deployed as subsystems) in SS7 nodes. TCAP is used for database services such as calling card, 800, and AIN, as well as switch-to-switch services including Repeat Dialing and Call Return.
Telephone User Part. 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.
A generic name given to an SS7 stack protocol at layer 4 or above, such as, ISUP, TUP, ICAP, MAP etc.
