Configuration Utilities
3.2 Before You Start
Whatever method you use to configure your TA, consider your choices beforehand
and record your selections on the following pages; then refer to them during the
configuration procedure.
Network Configuration
4 Network Switch Type ______________________________________________
Select the network switch type your ISDN service provider uses at its local
central office. You can set the MTA128ST to NET3 (DSS1), 1TR6, VN4,
INS64, NI-1, AT&T 5ESS, or DMS-100. If you do not know the switch type,
you can get the information from your ISDN service provider. AT command:
!C0=.
4 Data TEI ________________________________________________________
The Data TEI is the TEI that is 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 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
can also disable the channel, which may be useful when multiple TAs are at-
tached to a network terminator bus. AT command: !D3=.
4 Voice TEI _______________________________________________________
The Voice TEI is the TEI assigned to the voice channel. You have the same
choices as for the Voice TEI: Auto TEI, a fixed TEI number, or Disable.
AT command: *!D3=.
4 SPIDs and DNs __________________________________________________
The TA must be configured with the Service Profile Identifier (SPID). The
SPID is assigned by the local phone company and is for the specific BRI line to
which the TA will be attached. The SPID field will be empty prior to configu-
ration. AT commands: 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=.
