EAGLE - ANNEX A.2. ISDN NATIONAL-1 communications guide (USA) 55
The Eagle’s Universal Terminal Adapter can work with the NATIONAL-1 protocol (the most
widely used in the USA). Selection of the desired protocol, in our case the NATIONAL-1, must
be configured in the unit’s setup.
In Europe and in other geographic areas, there is a protocol called EURO ISDN. There are
minor differences between the EURO ISDN in different countries. These differences do not
affect the Eagle.
1.4.- Directory Numbers (DN’s)
These are the telephone directory numbers assigned to the line.
In the National-1 protocol, there will be two numbers, each associated with one of the line’s
channels. These numbers must be programmed in the unit for it to work correctly “NUMBER
LINE X” option) and therefore, each channel will only respond to its associated number (Note: In
the USA, the directory number that must be programmed in the terminal should not contain the
area code, in other words, use only the seven-digit local number.)
If the directory numbers are programmed incorrectly in the unit, it will be able to make outgoing
calls but will not respond to incoming calls.
1.5.- SPID’s (Service Profile Identification Numbers)
In the case of the NATIONAL-1 protocol, the SPID’s (Service Profile Identification Number) as
well as the directory numbers (DN’s) must be programmed in the terminal. SPID’s are numbers
that the phone company assigns, which are associated with each of the line’s two channels. If
the SPID’s are not configured correctly, the terminal will not work.
1.6.- Line characteristics for the USA. Model line request.
In the case of the USA, ISDN lines have many configurable parameters, such as the protocol
used, number of channels, type of call the channels accept (analog and digital, only analog,
etc.), etc.
To ensure that the line’s characteristics are appropriate for use with the Eagle, we recommend
you use the line request model of ANNEX A-9 to request it:
2.- Connecting the Eagle to the ISDN line
If the U interface is to be used (more common in the USA), the line will be connected to the RJ-
11 jack (6 pins) on the back of the equipment marked ISDN-ANSI, using a 6-pin modular
telephone cable (RJ-11 to RJ-11). Note that the connection point to the U interface provided by
the phone company may be a 6-pin RJ-11 type jack or an 8-pin RJ-45 type (the standard allows
both types). If the jack provided is an RJ-45 type, the RJ-11 connector (6 pins) on the cable
may be inserted into the center of the RJ-45 jack (8 pins).
