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=
