About your ISDN Simulator
Virtual Console’s “BRI-8U” ISDN simulator is an ISDN switch with eight BRI “U” interfaces, whichprovides call
switching services for Basic Rate Interface (BRI) terminal equipment. All our ISDN simulators conform to the
ISDN architecture and to individually programmable switch types (Table 1). Our products are extensively used
with ISDN routers, modems, ISDN telephones, faxes and commercial H.320 videoconferencing products.

Figure 1: ISDN Functional Architecture
User Manual
The ISDN simulator appears to the customer-side Functional Groupings as the Loop Termination (LT) at
the telephone central ofce. These Functional Groupings, examples of which are shown in, include ISDN-
compliant Terminal Equipment (TE1), Network Terminations (NT1 and NT2) and Terminal Adapters (TA).
To an NT1 or NT2, the simulator provides the “U” interfaces.
Over these physical interfaces ow the protocols described in Figure 2.
While Q.931, the ISDN primary “dialing” protocol, usually is used to set up dynamic ISDN calls, ISDN simulator
also supports semi-permanent “nailed up” B channels that act like private leased lines. Refer to ISDN Manager
chapter for conguring “Leased Line” mode.

Selecting a ISDN Switch type
User Manual
To use ISDN simulator you must set the switch type. Use drop down menu in ISDN Manager application to
select appropriate BRI switch type. Selected BRI switch type must match the one congured on ISDN device.
Once that is done, you will always need to set the phone numbers (i.e., DN) and, if the congured switch type
requires it, the SPID numbers.
“Caller ID”, or, in formal ISDN terminology, “calling number identication presentation”, is always enabled and a
part of standard call setup procedure dened in Q.931 standard.
Chapter 3: Product Description
The Virtual Consoles ISDN simulator provides a “Telco in a box” for a variety of device testing scenarios
including ISDN routers, modems, ISDN telephones, faxes and H.320 video conferencing stations Commercial

User Manual
The device has the most common connectors and indicators on its front panel. In a rack installation with
routers, you would typically want the front panel on the same side as the router interface connectors. Less
frequently used connectors and switches are on the back. Do note that the “Reset” button function can be
invoked remotely through the ISDN Manager interface.
Ports / Interfaces
The simulator has eight separate BRI “U” interfaces
Power
ISDN Console simulator is powered from a 9-12 DC or AC, 500 mA supply that plugs into a standard
household outlet. International power supplies are available if you need to use the device in a country that
does not use 120 VAC 60 Hz.
Note: Power supply may be slightly warm when operating.
The simulator does not provide inline power to connected ISDN devices. They will need independent power
sources.

User Manual
Cabling
Straight-through RS-232 cable with DB9 M/F connectors is supplied with each ISDN Simulator for the ISDN
Manager or console management. To connect ISDN devices to the simulator, also use a straight-through CAT3
or CAT5 cable with RJ45 connectors.
Controls
A hardware “Reset” button is on the back panel of the ISDN Simulator. You can also Reboot ISDN Simulator
remotely using ISDN Manager application or AT command (ATZ) sent via console port.
The button on simulator is labeled as “Reset”; the button in ISDN Manager is labeled as “Reboot”.
LEDs
Each of the eight RJ45 ports has two integrated Green LEDs (LEFT and RIGHT). The left LED on port 1 is
always “ON” to indicate presence of power, even when no device is connected. On all other ports, the right
LED turns solid GREEN when a device is connected at the physical layer. The left LED on all other ports, dark
until layer 2 initializes, turns green when layer 2 is up.
As layer 3 activity begins, the left and right LEDs will begin to blink. If the switch type requires SPIDs and a
SPID is invalid for a B channel, the associated channel LED -- left for B-channel 1, right for B-channel 2 -- will
blink slowly.
If either SPIDs are not required, or the correct SPID is used, once the B-channel 1 is up, the left LED will begin
blinking rapidly. In like manner, when the B-channel 2 comes up, the right LED will begin to blink rapidly.
Chapter 4: Controlling and Configuring your ISDN
Simulator
Your simulator is controlled by ISDN Manager application or AT commands. Connect to this COM port on your
PC to RS-232 port on simulator with the supplied 6-foot straight-through DB9 cable. We recommend that you
use the ISDN Manager application, which provides a graphic interface with several convenient click buttons.
In test racks, you may nd it more convenient to control simulator with AT commands.

Conguring the ISDN Simulator with ISDN Manager
Virtual Console’s “ISDN Manager” application is the principal means of conguring and controlling ISDN
simulators. It is a Windows application supported for Windows 2000 and Windows XP. The ISDN Manager
version for this product also supports 8-port BRI U, as well as PRI, simulators.
Figure 4: ISDN Manager Screens

User Manual
On the main screen, you set the “switch-type” (see Table 1).
To set individual port characteristics, click on the appropriate “Port” tab. The screen will then show the current
phone number and, when applicable, SPID number (see Table 6) for each B channel on the port. You can then
set the values as required.
If you need to congure a B channel in “nailed up”, “semi-permanent”, or “dedicated line” mode, check the
appropriate box at the top of the ISDN Manager screen.
Conguring ISDN Simulator via Terminal Server
Many test environments control all devices from a single point, using a terminal server to connect to all devices
at a remote site. You can control the ISDN simulator in this manner. You must set the asynchronous interface
on the terminal server to the values in Table 3, and use the commands in Table 5.

Flow Control Hardware
From a terminal server, since you cannot press display buttons, modem-style AT commands must be issued
for all functions.
Since these commands apply to B-channels, you need to understand which B channel numbers apply to which
physical U interface (Table 4).
Table 4: Conguring the ISDN Simulator via Terminal Interface
BRI physical interface First B-channel number Second B-channel number
Port 1 0 8
Port 2 1 9
Port 3 2 10
Port 4 3 11
Port 5 4 12
Port 6 5 13
Port 7 6 14
Port 8 7 15
Once you understand the logical numbering, you can complete the commands (Table 5). The “x” parameter in
this table refers to the BRI channel number in Table 4.
