  • PRI2 (e1-32) – define one PRI2 channel or a range of PRI2 channels via which call routing will be enabled.
  • VoIP (vxx,V) – calls are routed via the VoIP interface.
• Prefix list – prefixes to be used for a selected LCR row. Set up to 32 prefix lists.
  
  • Prefix list 1–32 – call routing will obey the rules set in Prefix list 1–32. The count of digits to be dialled is governed by the Prefixes setting. 
  • All prefixes – all the prefix lists are permitted. Prefix lists 1–32 will be searched from 1 to 32. The first match will be used routing. For incoming GSM calls, the Count of digits from the GSM incoming group parameter will be applied.
  • Count of digits – all the prefixes are permitted. Routing is only limited by the count of digits to be dialled. 
• Time limitation – set a time validity limitation for a selected LCR row.
• Weekend usage – enable/disable a row on weekends.
• Call duration limit – set the maximum duration (minutes) for an outgoing call to the GSM/UMTS network.
• Groups – define the outgoing GSM groups or interface via which outgoing calls will be routed from 2N^® StarGate. If the defined interface is inactive or the outgoing GSM group tariff is exhausted, the next row will be applied.
  • GSM groups 1–32 – outgoing GSM groups. Set the tariff to be used. Refer to the GSM outgoing groups subsection for details.
  • PRI1 (P) – ISDN PRI1 interface. Refer to the ISDN parameters subsection for details.
  • PRI2 (E) – ISDN PRI2 interface. Refer to the ISDN parameters subsection for details.
  • VoIP (V) – VoIP interface. Refer to the VoIP parameters subsection for details.
• Tariffs – select the tariff group (free minute counter) to be used for the outgoing call. Refer to the GSM outgoing groups subsection for details.
• Ignore tone detection in last group – having detected a user defined tone (refer to GSM basic settings), the GSM gateway automatically terminates the call and seeks for another call setup way. If this parameter is activated, the GSM gateway ignores the tone detection results and sets up a call when this is the only possible call establishing way.

CLIP Routing Table + CallBack

Use the table to set a fixed CLIP assignment of incoming CLIPs from GSM to the numbers of extensions to which incoming calls are routed automatically. Also, set the CLIP list in the GSM network for which CallBack is enabled.

• GSM number (CLIP) – user Id in GSM/UMTS.
• Used service
  
  • Autodial – enable/disable CLIP routing for the selected CLIP.
  • Reject call – reject call for the selected CLIP.
  • Ignore call – ignore call for the selected CLIP.
  • Tone dial-in – incoming GSM calls is accepted + dialtone is activated for the selected CLIP.   
  • DISA message dial-in – incoming GSM calls is accepted + voice message is activated for the selected CLIP. 
• Dial to VoIP/ISDN – VoIP/ISDN destination number for the CLIP routing function.
• Auto CallBack – enable/disable the CallBack function for the selected CLIP according to the Gateway configuration / GSM basic settings / Calls / Source interface for CallBack setting.
• Call duration limit  – set the maximum call duration (minutes).

Ethernet Configuration

This window helps you configure the Ethernet interface of your gateway.

• Use DHCP – enable/disable the DHCP client function in 2N^® StarGate / BlueTower.
• IP address – fixed IP address (v4) of the 2N^® StarGate / BlueTower Ethernet interface.
• Subnet mask – subnet mask for the 2N^® StarGate / BlueTower Ethernet interface.
• Default gateway – IP gateway IP address (v4) in the Ethernet network.
• DNS server1 – primary DNS server.
• DNS server2 – secondary DNS server. Used as a back-up when DNS server 1 is not functional.

Login Configuration

The window helps you set the access password and name for the 2N^® StarGate / BlueTower web interface. Use the same data for Telnet connection too.

Web Configuration

Set additional parameters for the gateway web interface.

• Auto logout – set the count of minutes in which the current user should be logged out automatically.
• Enable web session lock – by default, one Admin user may only be connected to the GSM gateway at a moment. If another authorised user tries to log in, the previous session will be aborted automatically. By activating this function you disable such automatic logout and block any further access attempts.
• Simple login form – change the login window graphic layout. Upon activation, the GSM gateway login page will have an anonymous appearance. This function is recommended for connecting the gateway to the Internet directly.
• Use SMS user for SMS operations on the web – enable/disable the user authorised for SMS sending/receiving only.
• SMS user name/password – the gateway enables independent connection of a user authorised for SMS receiving/sending only.

Report Configuration

This window is used for setting details on automatic tracing generated by the GSM gateway.
