Multi-Tech Systems ISIHP-4SD, ISIHP-4U manual D3=n TEI

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=0–63Sets 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.
