Chapter 4 - AT Commands, S-Registers, and Result Codes

Command: !D3=n

Function: SAPI-0 Data TEI

Values:

n = 0–63, 240 (auto), 241 (disable)

Default:

!D3=240 (Auto TEI)

Description:Use !D3= to set the terminal endpoint identifier (TEI) for the data channel. A

 

TEI is a number used by the central office switch to identify uniquely each

 

device 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 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 TEI to a fixed value from 0–63

 

!D3=240

Sets data channel for dynamic TEI negotiation

 

!D3=241

Disables TEI

Command: *!D3=n

 

Function:

SAPI-0 Voice TEI

Values:

n = 0–63, 240 (auto), 241 (disable)

Default:

*!D3=240 (Auto TEI)

Description:Use *!D3= to set the TA’s terminal endpoint identifier (TEI) for the voice

 

channel. See the !D3= command description.

 

*!D3=0–63

Sets TEI to a fixed value from 0–63

 

*!D3=240

Sets voice channel for dynamic TEI negotiation (default)

 

*!D3=241

Disables TEI

Command: !DN=n

 

Function:

Disable Data DN/MSN

Values:

n = 1 or 2

 

Default:

All ports are enabled.

Description:!DNn disables a Data DN/MSN which disables the associated TA port from

 

receiving any data calls. However, the port will still be able to originate data

 

calls. This is useful for applications where a specific port is for dial-out only.

 

Since the TA has only one serial port, both Data DN/MSN 1 and 2 would

 

have to be disabled to not accept a call. Disabling only one of the Data DN/

 

MSNs will cause the TA to not accept bonded calls (ML-PPP or Softbonding).

 

!DN=1

Disables Data DN/MSN 1

 

!DN=2

Disables Data DN/MSN 2

Command: *!DN=n

 

Function:

Disable Voice DN/MSN

Values:

n = 1

 

Default:

All ports are enabled.

Description:*!DNn disables a Voice DN/MSN which disables the associated TA port from receiving any voice calls. However, the port will still be able to originate voice calls. This is useful for applications where a specific port is for dial-out only or one does not want to accept voice calls at that time.

*!DN=1

Disables Voice DN/MSN 1
