Step 6
After the Simulator’s provisioning is established, press RESTART. The
settings are retained in non-volatile memory until you change them.
You now have two ISDN-BRI telephone lines ready to provide Circuit
Mode Voice (Speech, 3.1 kHz Audio, 7 kHz Audio), and/or Circuit
Mode Data (56 Kbs Restricted, 64 Kbs Clear) services on two B
Channels.
Step 7
Refer to the instructions supplied by the manufacturer for installing
your communications device or computer application on an ISDN-BRI
telephone line. For most devices, you will use a procedure similar to
the following:
NOTE: The instructions may specify that your communications device re-
quires power from a secondary source, such as a wall adapter. It may not be
necessary to connect a power source when using the Simulator. See Specifi-
cations for more details.
Step 8
Determine which ISDN-BRI interface is compatible with your device.
The interface may be either S/T or U. The S/T Interface is commonly
called the “Phone” outlet from an NT-1 and is used for most end-user
communications devices. However, some adapters and communica-
tions devices connect to the U Interface, also called the “Line” outlet.
Use 8-Pin Modular (RJ-45) telephone cord for all connections.
IMPORTANT: Either or both Simulator ports may be used during simulation,
but only one interface (S/T or U) may be selected at each port. The Simulator
auto-detects the active interface. If both interfaces at one port are connected,
the Simulator defaults to the S/T interface.
If your communications device is compatible with the S/T Interface, connect to the
Simulator’s S/T Interface at either port. Some instructions may require that the
device be connected to the “Phone” outlet of an Network Termination-1 (NT-1)
device. If you do not have an NT-1 available, use the Simulator’s S/T Interface.
Step 9
If you have an NT-1 and want to install it between your device and the
Simulator, connect the NT-1 “Line” outlet to the Simulator’s U Inter-
face at either port. Allow several seconds (5-30) for the port’s U-SYNC
light to turn green, then connect your communications device to a
“Phone” outlet on the NT-1. Most NT-1’s provide two “Phone” outlets,
providing a convenient method for connecting two devices at each
Simulator port.
NOTE: The Simulator’s U-SYNC light shows synchronization only for the U
Interface. The U-SYNC light is not an indicator for the S/T Interface, which
synchronizes in less than a second.
Step 10 Next, you may be instructed to program one or more identification
numbers into your communications device or computer application.
The numbers may be a Service Profile ID (SPID) and sometimes a
telephone number (Directory Number or DN). The Simulator, like an
ISDN switch, expects specific SPID’s and DN’s to be assigned to any
particular port. When programming these numbers into your commu-
nications device, you must assign the number(s) listed in the following
table:
