EAGLE - ANNEX A.2. ISDN NATIONAL-1 communications guide (USA) 56
3.- Configuration Parameters for the Eagle TA
3.1.- Terminal Adapter Configuration Menu
3.1.1.- ISDN U / ISDN S Selection
SETUP->TA CONFIG->ISDN U <*> (*indicates the option selected)
ISDN S < >
ISDN U should be selected if the U interface has been used (RJ-11 jack marked ISDN-ANSI). If
this option is configured incorrectly, the effect will be the same as if we did not have an ISDN
line connected (“Inactive” status with National-1 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.
