Before You Start

Refer to them during the configuration procedure. Before you begin, verify your switch type and TEI with your local ISDN provider and have that information readily available
Network Configuration
Network Switch Type _________________________________
Select the network switch type your ISDN service provider uses at its local central office. You can set the MTA128ST/NT to NET3 (DSS1), VN4, INS64, U.S.

Data TEI ___________________________________________
Data TEI is the TEI assigned to the data channel. You can select Auto TEI, a fixed TEI, or Disable. A TEI (terminal endpoint identifier) is a number used by the central office switch to uniquely identify each device connected to the network. When it uses dynamic TEI assignments (Auto TEI), the central office switch assigns a TEI each time the TA connects to the network. However, the ISDN service provider may assign a fixed TEI at subscription time, in which case you must configure the TA with the fixed TEI number. You also can disable the channel, which may be useful when multiple TAs are attached to a network terminator bus.
