Chapter 1 - Introduction and Description
dialing extension 201, dials extension 202 and is now connected to the local telephone network at the
sales office. The corporate caller could then dial any telephone number from the sales office PSTN
and this would be a local call.
The regional office is set up very similar to the corporate office with the exception that a MVP200 is
connected between the network and the PBX. This enables two voice/fax channels to be used at the
regional office. A person in the regional office can pick up a telephone and dial a trunk extension (for
example, trunk extension 10) on the local PBX. This is the same as dialing a 9 for an outside line. A
second dial tone is heard, the caller would then dial the corporate MultiVOIP at one of the following
extensions (101 thru 104). When the third dial tone is heard, the caller could then dial any telephone
at the corporate office by dialing its extension, for example, extension 4123.
To configure a MultiVOIP, the COM port of a PC is connected to the Command port on the MultiVOIP.
Configuration software is loaded onto your PC and your unique LAN parameters must be established.
The configuration software is based on a standard Windows Graphical User Interface (GUI) which
simplifies your selection process to a single parameter group within a dialog box. For example, your
LAN IP parameters are contained in a single dialog box as shown below. You can configure your
network IP address and mask for the MultiVOIP 400 and the gateway address for the corporate
router on the same dialog box.
For your corporate MultiVOIP, the Ethernet Frame Type is Type II, the IP Address is 201.22.122.118,
the Subnet Mask Address is 255.255.255.128, and the router Gateway Address is 201.22.122.1.
Once the LAN parameters are established, you can set up the voice channel parameters.
The channel setup parameters define the voice side of the MultiVOIP, the voice channel interface.
FXS (Ground and Loop Start) are for connecting to a standard analog telephone set, FXO (Foreign
Exchange Office) interface connects to the station side of a PBX, and E&M (Ear and Mouth)
connects to the trunk side of the PBX. Along with each interface there are additional parameters that
need to be considered, such as for FXO, the dialing options for DTMF (Touch-Tone) or Pulse, the
method of disconnecting (Current Loss or Tone Detection), and for E&M, signaling, mode, and the
wink timer settings in milliseconds.
In our typical application, you would configure the corporate office channel parameters for an E&M
interface. With this interface, you would have to consult with your in-house telephone people to
