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 find it more convenient to control simulator with AT commands.
