110 MultiModemISI Hybrid Series, ISIHP-2S/2U/4S/4U/4SD
Terminal Adapter AT Commands & S-Registers
Values: n = 0- to 20-character string
Default: null string
Specifies the channel 1 service profile identifier (SPID) that the ISDN
service provider assigned at subscription time. The voice SPID string can
have up to 20 characters.
Note: For DMS-100 switches, any ASCII character except the underline (_)
character is valid. For NI-1 and AT&T switches, only the digits 0–9 are
valid. (Not needed for NET3 switch type.
!D3=n TEI 0
Values: n = 0–63, 240 (auto), 241 (disable)
Default: !D3=240 (Auto TEI)
Sets the terminal endpoint identifier (TEI) for channel 0. A TEI is a number
used by the central office switch to identify uniquely 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. If your ISDN service provider assigned a fixed TEI at
subscription time, you must configure the TA with the fixed TEI number.
You can also use !D3= to disable the data channel, which may be useful
when multiple TAs are attached to a network terminator bus.
!D3=0–63 Sets the TEI to a fixed value from 0
through 63
!D3=240 Sets the data channel for dynamic TEI
negotiation (factory default)
!D3=241 Disables TEI
*!D3=n TEI 1
Values: n = 0–63, 240 (auto), 241 (disable)
Default: *!D3=240 (Auto TEI)
Sets the terminal endpoint identifier (TEI) for channel 1. A TEI is a number
used by the central office switch to identify uniquely 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.
