3.5 GSM Groups Menu

The menu helps you add, edit and view the GSM groups. 

Tip

  • Highlight the GSM / SIM groups by colour to make their listings clearer.
  • Create new GSM / SIM groups simply by copying an already established group. Click on the button in the list of GSM / SIM groups.

 Add GSM Group

Use this function to add new GSM groups to the configuration manually.

  • General info 
    • Description – type a text to be used for easier orientation in the configuration.
    • Highlighting – select the user colour codes for easier group listing.
  • Gateway routing – set the outgoing/incoming group for the LCR table of the GSM gateway whose modules are assigned to the selected GSM group. The following priorities are respected:
    1. SIM group (SIM card) setting;
    2. GSM group (GSM module) setting;
    3. User setting in the GSM gateway.
  • Outgoing group – select the outgoing group for the GSM gateway LCR table.
  • Incoming group – select the incoming group for the GSM gateway LCR table.
  • Recharging and activation – use this item to control the SIM card activation and recharging for the GSM modules of the selected GSM group. 
  • BTS lock – if the GSM modules in the selected GSM group support the BTS lock and the function licence is valid, 2N® SIM Star Server will send information on the required BTS to the gateway upon every GSM module login, i.e. upon every outgoing call.
    • BTS lock type – select the BTS type for GSM module locking:
      • Use the assignment table – the GSM modules will use the BTS as specified in the table below the selection.
      • Use random available BTS for each call – a different, randomly selected BTS with a signal level above the Minimum signal level value will be used for each new outgoing call.
    • MCC+MNC – network code for the selected BTS Id.
    • BCCH Freq – BTS code.

Caution

  • The GSM group assignment settings affect the call routing process in the GSM gateway connected. Therefore, leave the default parameters unchanged if in doubts.
  • If BTS is set incorrectly, the GSM module will be blocked and unable to log in to GSM/UMTS!

Tip

  • We recommend you to use the 2N® BTS Lock SW for finding the BTS Id. Connect the SW to a remote GSM gateway using the Telnet protocol and display the available BTS. Refer to the Management / GW & SB/SC firmware / Support files menu for this utility.
