    Chapter 6 - Async to Sync PPP and SLIP By default, the Omni TA128 dials the same number for both Multilink PPP connections. If the destination you are dialing requires two different telephone numbers to establish a two channel Multilink PPP connection, then the following command can be used: ATDIphone_number_1+phone_number_2 where phone_number_1 and phone_number_2 are the phone numbers of the destination.

  • Page 46: Answering Incoming Calls

    In most cases, there is no need to configure the Omni TA128 to properly answer calls. The Omni TA128 is able to decide which protocol to use by detecting the type of data that is coming in. All you need to do is set S0 to greater than or equal to 1, so the Omni TA128 will automatically answer an incoming call.

  • Page 49 Chapter 7 - V.120 ISDN Communications It takes extra time for the calling ISDN TA to negotiate V.42bis. If you know in advance that the called site has no V.42bis capability, it would be better to issue the AT&K00 command beforehand in order to get a quick connection. V.42bis is an international data compression standard commonly used in modem communications.
