Glossary

This chapter provides a brief list of terms used in this guide.

A

The hardware component (the LS1010) used in conjunction with your virtual switch controller system. Also referred to as access server.

The Cisco network access server for the virtual switch controller is the LS1010.

Adjacent point code. The point code of the next hop in the system for the bearer channels; usually it is the STP (signal transfer point).

Application Programming Interface.

Small program, often used in the context of a Java-based program, that is compiled and embedded in an HTML page.

Auxiliary signaling network.

Asynchronous transfer mode.

B

Create flat files that are ready for use by the VSC database.

C

The piece of hardware into which cards are installed.

Common channel signaling.

Circuit Emulation Services. A circuit type (called endpoints in SGCP).

Proprietary Cisco protocol based on ISUP.

Element management service tool that has a GUI.

Common Object Request Broker Architecture.

Continuity testing. COT is a requirement of the SS7 protocol specifications. It tests the bearer channels' status using either loopback or tone detection and generation.

Coding Unit. A type of access device. (See Access Device.)

D

Dial Access Solution. Cisco's SS7 DAS product connects Cisco Access Servers to the SS7 network. Uses different configuration than the VSC solution.

Send flat files that are ready for use to the VSC data repository.

Destination point code. This is part of the routing information for a signal.

G

Graphical user interface.

H

Hypertext Markup Language.

I

Information element.

Integrated Services Digital Network (ISDN) User Part. An upper-layer application supported by SS7 for connection set up and tear down.

J

Java Database Connectivity.

L

The set of signal channels for an SS7or C7 signal path purchased from a carrier. Each has a unique signaling link code.

N

Network access server. A type of access device. (See Access Device.)

Network Element Management System.

The highest level of your VSC system. You have only one network, within which you create your sites.

The network indicator determines the type of call that is being placed: 0 = international, 1 = reserved, 2= national, and 3 = national spare.

O

Open Database Connectivity.

Own point code. The point code of the Cisco VSC2700 virtual switch controller.

P

Private branch exchange.

S

Simple Gateway Control Protocol. Used for controlling Voice over IP gateways by an external call control element (called a call-agent in SGCP).

Route of a signal channel that carries signaling data.

A group of closely related configuration data. It can be the name of a physical location or it can be a name you choose to give to one segment of your overall system.

Signaling link code. Code that identifies a linkset.

Simple Network Management Protocol. It is used almost exclusively in TCP/IP networks and provides a means to monitor and control network devices and to manage configurations, statistics collection, performance, and security.

Signaling System 7. A digital signaling system.

Signal transfer point.

Service unit (telephony) or signaling unit.

T

A Cisco Technical Assistance Center. There are 4 TACs worldwide. See "Preface" for more information.

Identification information, including a number plus other information.

Route of a bearer channel that carries voice traffic.

The part of your telephony controller system where signals are identified, converted, and routed.

V

Voice over asynchronous transfer mode.
