central office. You can set the TA to NET3, AT&T 5ESS, NT DMS- 100, or US National ISDN-1. If you don't know the switch type, get the information from the local phone company. AT command: !CO=

•SPIDs and DNs ________________________

The TA must be configured with the Service Profile Identifier (SPID). The SPID, assigned by the local phone company, is for the specific BRI line where TA is attached. The SPID field is empty prior to configuration. AT command: AT!C6= and AT*!C6

The Directory Number (DN) is the phone number another user would call to contact this TA once it is attached to the ISDN. AT commands: AT!N1= and AT*!N1=

Note: SPIDs only apply for North American switch types.

International Users

The terminal adapters ship already configured for NET3, which should work for most telephone lines in Europe. If you want to customize settings, refer to the “Optional Settings” below.

Optional Settings

•Data TEI _____________________________

The Data TEI is the TEI (terminal endpoint identifier) assigned to the data channel. You can select Auto TEI, a fixed TEI, or Disable. A TEI is a number used by the central office switch to uniquely identify each device that is 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. AT command: !D3=

•Voice TEI _____________________________

The Voice TEI is the TEI assigned to the voice channel. You have the same choices as for Data TEI: Auto TEI, fixed TEI number, or Disable.

AT command: *!D3=
