| Server | A networked computer that stores information and makes it available upon request
to client programs that may be located on other computers. "Client-server"
computing is the basis of virtually all local area networks and the World Wide
Web.

| Service Control Point (SCP) | The node in the common channel
signaling network to which informational requests for service handling,
such as routing, are directed and processed. The SCP is a real time database
system that, based on a query from a service
switching point (SSP) and via a signaling
transfer point (STP), performs subscriber or application-specific service
logic; then sends instructions back to the service switching point on how to
continue call processing.
|

| Service Switching Point (SSP) | A Signaling Point that can launch queries to
databases and receive/interpret responses used to provide specific customer
services.
|
| | |
| Signaling Point (SP) | A node in the CCS network that
originates and/or receives signaling messages, or transfers signaling messages
from one signaling link to another, or both.
|
| | |
| Signaling System 7 (SS7) | A digital data network carrying signaling information that interfaces with
the telephone company voice/data network for services using the American National Standards Institute (ANSI) Common
Channel Signaling (CCS7) protocol. Also known as CCS/SS7.
|
| | |
| Signaling System 7 Network | A digital data network carrying signaling information that interfaces with
the telephone company voice/data network for services using the American National Standards Institute (ANSI) Common
Channel Signaling (CCS7) protocol.
|
| | |
| Signaling Transfer Point (STP) | A specialized switch that provides SS7 network
access and performs SS7 message routing, screeningand transfer of signaling
message through the common
channel signaling network.

| SIP | The Session Initiation Protocol (SIP) is an Internet Engineering Task Force (IETF ) standard protocol for initiating an interactive user session that involves multimedia elements such as video, voice, chat, gaming, and virtual reality.

| softphone | Softphone: A softphone is a multi-media application
that works in association with VoiP technology enabling you to make
calls direct from your PC or laptop.

| SONET (Synchronous Optical Network) |
- An optical interface standard that allows different digital signals to be transported
using a base transmission rate of 51.84 megabits per second OC-1
(Optical Carrier) STS-1 (Synchronous
Transport Signal). Higher rates are direct multiples of the basic OC-1 building block.
- A
Private Line service offered through Verizon Wholesale that uses
industry standard interfaces for implementing a robust, survivable
transport technology.

| Switch |
A device that can be controlled to interconnect two circuits.
In the context of Frame or LAN
switching, this refers to a device that filters, forwards and floods frames
based on the frame destination address. The switch learns the addresses associated
with each switch port and builds tables based on
this information to be used for the switching decision. Some switches are high
speed implementations of bridges where switching
decisions are made by computer chips, usually an Application Specific Integrated
Circuit (ASIC).

| Synchronous | A form of communications where characters or bits are sent in a continuous
stream, with the beginning of one signal continuous with the end of the preceding
one; separation of one from the other requires the receiver to maintain a synchronization
to a master timing signal.
|
| | |
| Synchronous Optical Network (SONET) | An optical interface standard that allows different digital signals to be transported
using a base transmission rate of 51.84 megabits per second OC-1 (Optical
Carrier) / STS-1Synchronous Transport
Signal). Higher rates are direct multiples of the basic OC-1 building block. (
