Second device at Port 2:
SPID 0835866401
DN
835-8664
(1-800-835-8664)
NOTE: Not all communications devices are programmed with a SPID or
DN. Some devices need an additional number called a Terminal
Endpoint Identifier (TEI). If you must assign a TEI, use a different
number (between 1 and 63) for each device you connect to the
Simulator. If automatic TEI assignment is a selectable option, choose it.
In short, follow the instructions for your device, using the numbers
listed above, when applicable.
Step 11
After any identification numbers are programmed into your
device, it notifies the Simulator using an initialization
procedure. If the procedure is successful, and your device is
connected to the U interface, the U-SYNC LED will light after
synchronization is complete.
NOTE: If the U-SYNC LED does not turn on, the device may need to be
rebooted or momentarily disconnected (powered down) and
reconnected to make it initialize. If the device did not require SPID
programming, the U-SYNC LED may not turn on until you place your
first call.
Step 12
Repeat the above steps for additional devices. The Simulator
provides power for up to four communications devices and two
NT-1’s. Each communications device must be programmed
with a different SPID and/or DN.
Step 13
If you later need to rearrange the connections between the
Simulator and your devices, disconnect the devices from the
Simulator, press RESTART on the Simulator’s power switch,
wait for the STATUS LED to turn to a solid green, then
reconnect your devices. If you move a device from one port to
another, its SPID and DN must be reprogrammed using
available numbers from Table 1. You do not need to restart
simulation if you change a device’s SPID or DN when it
remains at the same port.
IMPORTANT: Some devices let you change the ISDN protocol to
support the type of ISDN switch the telephone company has installed. If
you change your device’s protocol, you must change the Simulator’s
Switch Type configuration to match. If you change any one device’s
ISDN protocol, then all devices connected to the Simulator must be
configured for that protocol.
Step 14
Now you can operate your devices as recommended by the
manufacturer.
