How do I set up a wireless 3G connection?

Connecting your codec over 3G is very similar in principle to connecting over IP. The only difference is that you are wirelessly connecting to your ISP instead of connecting via a LAN. Connect to your ISP/cell-phone provider and then use the Quick Start connection procedure for your preferred connection profile (i.e. mono, stereo, mono/IFB and dual mono program) over IP.


Very Important Warning:

Tieline CDMA EV-DO 3G modules don’t use SIM cards and need to be activated and provisioned in order to connect to cell-phone networks in the U.S.A. Use the procedure outlined in this manual to program your module before use over these networks. 

Important Note:

As a factory default, GSM/3G settings are programmed for AUTODETECT. If you plug a 3G or USB module (with a 3G phone connected) into your codec it will program it to operate in 3GIP mode by default. If you use a GSM module or plug a GSM cell-phone into the serial port of your codec it will program it to operate in GSM CSD mode by default. If you wish to use a 3G phone in GSM mode, you will need to change the Wireless Network setting in the GSM/3G Wizard to either GSM CSD or GSM HSCSD - depending on the connection you wish to use. The "Ss" wireless signal strength reading on the codec screen should be between 4 and 9 to connect reliably.
  1. Insert a Tieline 3G module (with a SIM card installed for UMTS/HSDPA networks or provisioned & activated for EV-DO networks) into your codec and then power up the codec.
  2. Scroll to the 3GIP1 connection with the codec MENU SELECTOR and press SOFTKEY 3 Wiz and then select SOFTKEY 4 OK. Next select [Wireless Network →3G/UMTS IP] > [3G/UMTS IP Network →select your network] > [Auto Reconnect Disable]. Select SOFTKEY 4 OK to complete configuration and return to the main LCD connection screen.
  3. If 3GIP1> Prs Entr is displayed, press ENTER/DIAL to connect to your 3G network. If 3GIP1> Enter # is displayed, dial the SIM card cell-phone number using the codec keypad and then press ENTER/DIAL to connect to your 3G network. This is because some cell-phone networks require you to dial this number to connect.
  4. Once you have connected the codec connection will display 3GIP1> Cntd Goto IP
  5. Now scroll to IP1 on the main codec LCD screen and connect using the Quick Start IP profile you have selected, i.e. mono, stereo, mono/IFB or dual mono. Type the IP address of the codec you are dialing. (Note: Use the * or # button on the codec keypad to enter the periods (.) in the IP address).
  6. Press the ENTER DIAL button on the remote codec’s grey keypad to begin dialing. In many situations it is only possible to dial from the remote codec to the local codec with IP connections because only the studio codec is using a public IP address.
  7. Try to maintain a link quality (LQ) reading for your connection of between 70% and 100%.To negotiate higher bit-rates press “F2” then “3”; for lower bit-rates press “F2” then “9”. For best performance, the dialing codec should be used to renegotiate connection bitrates up and down. If you hear audio drop-outs the current bit rate cannot be sustained and should be renegotiated down.
  8. To disconnect, hang up your IP connection and then hang up the 3G connection.
  9. To change other 3GIP settings select SOFTKEY 4 OK and scroll to [Configuration] > [GSM/3G Setup] > [3G Module].

Note on Cell-phone Use with Tieline USB Modules:

Turn on your 3G cell-phone and wait 30 seconds before you connect the phone to the USB module via its USB cable (this cable should be available from your cell-phone manufacturer). Within 30 seconds a 3GIP1 connection should appear on the main codec connection LCD screen.
