Installing a Modem Card
An installed modem card will appear as an additional serial port on the MSS. If only one card is installed,
the card will appear as Port 5 regardless of which slot it is in. If two cards are installed, the card installed in
the top slot (slot 1) will appear as Port 5 and the card in the bottom slot (slot 2) will appear as Port 6.
If you are an SDK user, you can access the port by using device “tt4” for port 5 or “tt5” for port 6.
Follow these steps to properly install supported modem cards.
1 Power off the MSS by unplugging its power cable.
2 Insert a supported modem card into one of the PC card slots.
3 If desired, insert another supported modem card into the other PC card slot.
4 Power up the MSS by plugging its power cable into the outlet.
The MSS should boot up normally.
