TVP-221H User’s Guide

Draw an application diagram to illustrate / clarify application including:

1.Local gateway: IP setup

2.Local gateway: local telephone number setup

3.Local gateway: remote gateway IP & remote telephone number setup

Note: The Diagram below of Gateway A & B could be any combination of either the TVP-224HR (connected to switch by WAN port) or the TVP-221H (Connected by LAN port). The switch that joins these two gateways serves the purpose of initial lab configuration. Under this configuration, both GW must be in the same IP segment. Once the dial plans have been entered and tested, the switch would be replaced by the public internet and the gateways would then have to be updated with the field application Internet Access Settings (eg. Public IP Address, Subnet Mask and Gateway IP Address). In addition, all remote destinations in the dial plan must be updated with the actual application / field IP Addresses.

This diagram serves the purpose of illustrating the possible analog phone / PBX / PSTN integration / applications of the Gateway. However, disconnect cadence provided by your phone company for your PSTN line and disconnect cadence provided by your PBX may require additional matching with the gateway. This will require the assistance of your PBX supplier and /or Systems Integrator. Please also see User’s Guide for additional information.
