PRI1 and PRI2
TEI address – The Terminal Equipment Identification number for the ISDN PRI
line connected. The TEI must be identical for both devices on one ISDN PRI line.
The default value is 0.
CRC – Enable/disable receiving CRC on Layer 1 on the ISDN PRI interfaces (in
both modes the gateway sends the CRC).
Progress Indicator Value
Define which progress element value will be sent in the selected ISDN messages. The
correct setting of these parameters depends on the current settings of the opposite
device (PBX / Router). This parameter is primarily designed for opening the B–channel
before call connection – transferring call state tones (e.g. ringing tone) from GSM /
UMTS networks. The following table contains common values of progress elements.
