Term Definitions
Audio Group
– a group of audio I/O channels combined for the purpose of sending voice or other audio to
multiple channels simultaneously. A common audio group would be
“all call”.
Channel
– an addressable access point on a Valcom IP paging system endpoint. Endpoints may have one or
more channels. These channels may be audio I/Os, FXO ports, FXS ports, I/O endpoints or SIP Servers. Each
channel must be assigned a unique dial code. For example, a VIP-801 Page Endpoint has a single audio I/O that
may be accessed by an assigned dial code, and therefore is a single channel device. By contrast, a VIP-824
Trunk Endpoint features four FXO ports that may be independently accessed by assigned dial codes, therefore it
is a four channel device. Individual end points have unique IP addresses, however, depending upon the endpoint,
each IP address may represent one, two or four channels.
Control Group
– Control Groups allow users to combine relays from I/O Units into groups so that they may be
controlled simultaneously. These are only used with the VIP-848 devices.
Device/Endpoint
– a component of a Valcom IP paging system that connects to the Ethernet network.
Dial Code
– a numerical address used to communicate with channels. This is sometimes referred to as a
Directory Number or Phone Number. All devices in the system must have the same length of dial code (number
of digits).
DTMF
– Dual Tone Multi-Frequency is the combination of two different frequencies to create one tone. This is
also commonly called Tone dialing.
SIP (Session Initiation Protocol)
– a standard network protocol for negotiating parameters for Voice over IP
communication.
DSCP
(Differentiate Services Code Point) -- Differentiated Services Code Point (DSCP) is a field in an IP packet
that enables different levels of service to be assigned to network traffic. This is achieved by marking each packet
on the network with a DSCP code and appropriating to it the corresponding level of service.
