  • Page 4: Chapter 1: Introduction And Description

    You have acquired one of the finest ISDN terminal adapters (TAs) available today, model MTA128ST/NT from Multi-Tech Systems. The MTA128ST is a desktop TA with an S/T interface port to connect it to the ISDN network and an analog port to connect it to a telephone, modem, or fax machine. The MTA128NT is a desktop TA with a U-interface to connect it to the ISDN network and an analog port to connect it to a telephone, modem, or fax machine.

    POTS port via an RJ-11 jack. This User Guide will help you install, configure, and operate your terminal adapter. Features The MTA128ST/NT communicates over public ISDN telephone lines. Features include: • Compatibility with EuroISDN (ETSI/DSS1/NET3), French VN4, and Japanese INS64 switch protocols •...
  • Page 6 If your ISDN product operates with a S/T outlet interface, you need an NT1 device to connect to the ISDN switch. MTA128ST adapters need an NT1 device to connect to the ISDN switch, but the MTA128NT adapter does not require NT1 device. In the UK, and in many European countries, NT1 device is supplied by your telephone company.

  • Page 39 MTA128ST/NT does not. The MTA128ST/NT is looking for a SABME command from the Impact IQ to finish establishing the V.120 connection. However, the Impact IQ won’t send a SABME until it has data to send. Have the Impact IQ send a character by pressing any key (such as the space bar) on the terminal attached to the Impact IQ.
  • Page 40 AT”HO (that’s a double quote) and then establish the data connection again. The garbage characters should disappear. Each time a 3Com Sonix terminal adapter originates a V.120 call, the MTA128ST answers the call as a V.110 call. The Sonix sends V.110 information in the SETUP message to the network. Since the MTA128ST’s default is with Auto Protocol Detection enabled (ATS52=1), it looks at SETUP information from the Sonix and determines erroneously that it is a V.110 call.
