Troubleshooting the SCOTTY I-Split

Before you contact our support team, there are a lot of small checks that you can run, which might resolve your problem.

Quick check list:

• Is the I-Split receiving power (check green “PWR” LED)?

• Is the telephone number correct (note: USA locations often require two telephone numbers)?

• Are you sure your ISDN device is dialing (green “CN” LED’s blinking during call)?

• Is the ISDN device and the network set for Euro ISDN?

• Is the ISDN device set for 2x64 kbps calls (i.e. 1 BRI non “Bonding”)?

• Is the network really working properly and configured for high speed data?
  
  Inmarsat users: the terminal must be registered for high speed data, the signal should be at high, the batteries should be full.
  
  Check the GAN’s display while calling, is the call being rejected by the network?
  
  Is the Inmarsat network congested?

Isolate the problem:

• Can you make a 64 kbps call without using the I-Split?

• Can you make a 64 kbps call with the I-Split?

• Can you receive calls?

• Does replacing or exchanging the cables help?

• Do different network options work?
  
  Inmarsat GAN users: exchange or replace the GANs, try terrestrial ISDN.

• Can you connect to a different location?

• Do other end-devices function on this network (e.g. other videoconferencing equipment or PC with an ISDN card)?

• Inmarsat users: does changing satellites, LES’s help?

Quick fixes:

• Try resetting the I-Split (press red “RST” button).

• Try restarting the ISDN device.

• Try restarting the network access equipment (e.g. TA, NT Box, Inmarsat modem).

• Inmarsat GAN users: try waiting a few hours, try a different LES and/or satellite, try using two separate satellites or LES’s - sometimes the network is simply congested.
