EAGLE - ANNEX A.3. EUROISDN communications guide (EUROPE) 62
3.1.1.- ISDN U / ISDN S Selection
SETUP->TA CONFIG->ISDN U <*> (* indicates the option selected)
ISDN S < >
Allows the type of physical interface used for the connection to the ISDN to be configured. If the
S interface has been used (RJ-45 connector marked ISDN-ETSI), select ISDN S, and if the U
interface has been used (RJ-11 connector marked ISDN-ANSI), select ISDN U.
If this option is configured incorrectly, the effect will be the same as if we did not have the ISDN
line connected (“Inactive” status with National-1 protocol and “ISDN Link Error” message when
trying to make a call with EUROISDN protocol).
3.1.2.- TEI MODE Configuration
SETUP->TA CONFIG-> ISDN X <*>-> TEI MODE -> DYNAMIC <*>
FIXED < >
The TEI (Terminal Endpoint Identification) is an identification number used in the signaling
protocol to identify each terminal connected to the same ISDN line.
The “TEI MODE” parameter allows the assignment of the TEI identifier to be configured as
DYNAMIC or FIXED mode. The dynamic mode lets the network assign the TEI. In the fixed
mode, the terminal forces a TEI = 0.
The choice of one mode or the other is only important in some special types of lines that only
allow one of the two possibilities. In general, this parameter will be left in the DYNAMIC mode.
3.1.3.- PROTOCOL Configuration
SETUP->TA CONFIG-> ISDN X <*>-> PROTOCOL -> NATIONAL-1 <*>
EUROISDN < >
This defines the protocol used by the Terminal Adapter. There are two options: the NATIONAL-
1, which is the one most used in the USA, and the EUROISDN, which is the standard protocol in
Europe.
When the National-1 protocol is configured, the line status will go through several stages before
reaching “Ready.” First it will show “Inactive,” indicating that the line is in the process of
activation, then it will show “SPID pending,” indicating that the line has been activated and is in
the process of sending the SPID’s; and finally, it will show “Ready” if the SPID has been sent
correctly, or “SPID error” if the exchange did not recognize the SPID.
When the EUROISDN protocol is configured, the line status will go directly to “Ready.”
If the NATIONAL-1 protocol is configured by mistake on a line with EUROISDN protocol, the line
status will continue to show “Inactive” or “SPID pending,” and calls cannot be made.
3.1.4.- NUMBER LINE 1 and NUMBER LINE 2
SETUP-> TA CONFIG-> ISDN X <*>-> NUMBER LINE 1 -> "Number Channel 1”
SETUP-> TA CONFIG-> ISDN X <*>-> NUMBER LINE 2 -> "Number Channel 2”
These define the Directory Numbers (DN’s) for each of the ISDN line’s channels. If the National-
1 protocol is being used, their configuration is mandatory. If EUROISDN is being used, their
configuration is optional (they can be left blank). If a number is programmed for a certain
channel, that channel will only respond to incoming calls made to that number.
If these numbers are programmed incorrectly, the unit will allow outgoing calls but will not
receive calls.
