1.4 System Parameters
The following information is the knowledge required for installing and
operating the IS425A.

Contact your local telephone company to find out the correct switch type.
The IS425A software supports the following switch types.
•AT&T 5ESS Custom
•AT&T 5ESS National ISDN-1 (NI-1)

Service Profile IDentifier (SPID)
When you subscribe to the ISDN line, you need to determine how many
SPIDs (one to eight per ISDN line) your application requires. The IS425A
can use either one or two SPIDs. The most frequently used SPID formats are:
FORMAT DETAIL
AArea Code + Phone Number + Suffix
B01 + Phone Number + Suffix
These formats are defined as follows:
1. “Area Code” is the standard three-digit area code.
2. “Phone Number” is the standard seven-digit phone number, also
called the Directory Number (DN).
3. “Suffix”
•For Format A, the suffix could be:
a) 0101 d) 0100
b) 0000 e) 000

2 Hardware Installation
2.1 General Procedures
To ensure a successful installation, we recommend that the installer
prepare the following items before proceeding:
1. Select adequate communication software (HyperTerminal, Terminal,
ProComm Plus, etc.)
Note: For the operation and installation of the communication software, please
refer to the communication software manual.
♦If you want to use the AT commands set with Windows 95
then HyperTerminal is the communications software supplied
by Microsoft. (We suggest using the BLACK BOXbMan to
Machine Interface software instead of the AT command set.)
♦You may use the AT command set if you are using Windows
3.X via the Terminal software or any similar software. The
MMI may or may not work on your version of Windows 3.X
2. Subscribe to ISDN from your telephone service provider. Tell the
telephone service provider that you are going to use an ISDN
Terminal Adapter with a built in NT1. Refer to Chapter 10 for a
detailed explanation of ISDN ordering.
3. Have your personal computer (PC) or workstation ready.
4. Check the packing list. If something is missing, please contact Black
Box for assistance.

2.3 Installing the IS425A
Plug It In
⇒Warning: Always turn the IS425A power off before connecting
or disconnecting cables.
1. Plug the DB9 cable into the IS425A’s DATA Port. Insert the other
end of the cable into a communication port on the PC/workstation or
other Data Terminal Equipment (DTE).
2. Plug the RJ11 cable into the IS425A’s U-Interface. Insert the other
end of the cable into the ISDN wall jack.
3. Plug the RJ45 cable into the IS425A’s S/T-Interface. Insert the other
end of the cable into the ISDN S/T terminal equipment.
4. Plug another RJ11 cable into the IS425A’s Tel 1 and/or Tel 2 Port.
Insert the other end of the cable into any analog device (traditional
telephone, modem, fax machine or answering machine).
5. Plug the AC/DC power adapter into the POWER connector.
6. Secure the power adapter cord on the rear panel by using the attached
hook on the right side of the POWER connector.
7. Insert the other end of the AC/DC power adapter into the wall socket.
Termination Resistance Setting
You may need to adjust the termination resistor if your IS425A is
connected to any other ISDN terminal equipment, especially ISDN
phones. Position DIP Switches 7 and 8 on the rear panel to set the
termination resistance. In most cases, the default setting is 100Ω.
Switch Positions ON OFF
DIP Switch7 100Ω0Ω
DIP Switch8 100Ω0Ω
S/T Bus
Termination If an equal amount of resistance (0 to 100 Ohms) is
applied to both the IS425A and to the S/T
equipment farthest from the IS425A, it assures the
maximum power of the transmitted signal, thus it
improves signal quality.

Turn on the Power
Please check the LED indicators when you turn the power switch ON. All
the LEDs should flash in a preset sequence for a few seconds. If the U-
Interface line is not plugged into the IS425A then the LED indicators will
stop flashing and only the green Power LED and the red Line LED will be
lit. If the U-Interface is connected, the Line LED will turn green.
Congratulations you have just installed the IS425A!
