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.
Value Meaning Event
0 No progress element sending B-channel closed
1 Call is not end-to-end ISDN or may be in-band information B-channel opened
2 Destination call address is non-ISDN B-channel opened
3 Origination call address is non-ISDN B-channel opened
4 Call has returned to the ISDN B-channel closed
8 In-band treatment has been applied B-channel opened
10 Delay in response at the call interface B-channel closed
PRI Functions
– set this value to enableDay of deleting statistics on PRI (every month)
deletion of statistic data on x-th day of a month.
– sDigits count in SETUP (en-block) et the number of digits to be sent in the
SETUP message as ENBLOCK. The others digits will be sent in the OVERLAP dial
mode. Example of use:
Called party number: 6012345678, digits count in SETUP = 7
Outgoing signalling messages: SETUP (contains 6012345)
INFO (6)
INFO (7)
INFO (8)
– with this parameter activated, theReceive dial number from Subaddress
gateway uses the digits in the Subaddress field instead of the Called party
number for outgoing dialling.
– a specific feature designed for theHungarian dial tone after 2 digits
Hungarian national dialling plan. The gateway activates a specific dialtone for
second dialling after receiving two digits.
– when the ISDN PRI is in the TE mode, theDon't send ConnectAck on TE
gateway will not send the CONNECT_ACK message.
Use CLIR if requested from ISDN (SETUP) – enable automatic CLIR
resending to GSM/UMTS if required so by the ISDN.
Caution
Wrong settings of these parameters may cause malfunction of the ISDN
PRI line (call connection)!
