STE User’s Manual Installation
Rel. 2.6 2-13
1 is a small electronic box that, if you need one it must be purchased by a STE user. An example of an
NT-1 is the Tone Commander NTIU-220TC. For more information about them, call 800-245-9780 or visit
their web site at: http://www.tonecommander.com. Other sources are also available.
A STE needs the NT-1 to operate on a U-interface; however, it needs no additional parts for the S/T-
interface.
If required, enter the information in
Table 2-14 .
STEP 7: Determine where the ISDN Line will be physically terminated.
The service provider will install the line up to the point of connecting it to your facility. Once connected it
is usually your telecom department’s responsibility to run the wiring to the exact STE location. The STE is
a point-to-point ISDN device requiring an S/T (RJ-45) type connection. Point-to-point is defined as having
“one Terminal Equipment per ISDN line.” Make sure you write down all the information about your ISDN
service in
Table 2-14 as it is required to program the STE during the installation phase.
2-5.1.2 ISDN Connector Pin-outs
The ISDN PORT , an RJ-45 connector, is located on the rear of the STE. An ISDN Network Cable is
provided to connect the STE to a wall jack. Make sure your wall jack, or a pre-connected wire that will
mate to the STE, is wired as shown in
Table 2-15 .
Table 2-15. ISDN Connector Pin-outs
Pin Signal Name Pin Signal Name
1 No Connection 5 ISDN RX-
2 No Connection 6 ISDN TX-
3 ISDN TX+ 7 No Connection
4 ISDN RX+ 8 No Connection
2-5.1.3 Additional ISDN Information
For additional information for ISDN, please go to the government web site at:
http://wired.securephone.net or http://www.securephone.net (then select wired…).
2-5.2 Set ACTIVE NETWORK PORT to ISDN
The STE must have power applied but should not be connected to the ISDN service while making the
initial settings. You do not need a FORTEZZA PLUS
KRYPTON™
ENHANCED CRYPTOCARD for any
installation procedure, including placing the initial (test) call.
Make sure you have received all the installation information from your service provider for
Table 2-14 as it
is required to program the STE.
See Figure 2-1 to locate switches and connector. At the rear of the STE unit, set both ISDN
TERMINATION SWITCHES to “ON” (up position).
The ACTIVE NETWORK PORT setting determines which service the STE will use to operate. Table 2-16
provides a listing of the variables associated with the ISDN service and the factory default settings. Use
the service provider information in
Table 2-14 to make the settings the following procedures.
