Virtual TA Concepts 

The term 

Virtual TA 

means the local Ethernet-connected hosts or PCs use popular 

CAPI-based software such as RVS-COM or BVRP etc. to access the router as a 

local ISDN TA for FAX sending or receiving via the ISDN line. Basically, it is a 

client/server network model. The Virtual TA server built into the router handles the 

connection establishment and release. The Virtual TA client, installed in the 

Ethernet-connected host, creates a CAPI-based driver to relay all CAPI messages 

between applications and the router's CAPI module. 

Note

: 

1. The Virtual TA client is only supported on Microsoft Windows 95 OSR2.1/98/98 

SE/Me/2000 platforms. 

2. The Virtual TA client only supports the CAPI 2.0 protocol and has no built-in 

FAX engine. 

3. One ISDN BRI interface only has two B channels. The maximum number of 

active clients is also 2. 

4. Before you set up the Virtual TA, you must set the correct country code. Click 

ISDN Setup

 in the 

Basic Setup 

group. 

As the following application chart shows, the Virtual TA client can make an 

outgoing call or accept an incoming call to/from a peer FAX machine or ISDN TA 

etc.
