96 MultiModemISI Hybrid Series, ISIHI-2S/2U
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes
*!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.
*!D3=0-63 Sets the TEI to a fixed value from 0 through 63
*!D3=240 Sets voice channel for dynamic TEI negotiation (factory default)
*!D3=241 Disables TEI
!L Display Network Configuration
Values: n/a
Default: n/a
Displays the current DN, SPID, TEI, Data protocol, and switch type.
!L Displays the current network configuration
>Dn Embedded Protocol Analyzer
Values: 0, 1, 2, 3, 98, or 99
Default: n/a
Records and analyzes various protocols on the B-channel, D-channel, and DTE-DCE
interface. The Embedded Protocol Analyzer is useful as a diagnostic tool, in that essential
data messages display, which enables you to observe interactive operations of the TA,
Central Exchange, and remote communications equipment.
>D0 Displays B-channel traffic, decoded as V.120
>D1 Displays D-channel traffic, decoding layers 2 and 3 (Q.921 and Q.931)
>D2 Displays D-channel traffic, decoding layer 2 only (Q.921)
>D3 Displays D-channel traffic, decoding layer 3 only (Q.931)
>D5 Displays async PPP data
>D6 Displays sync PPP data
>D98 Disables Embedded Protocol Analyzer, buffered data unchanged
>D99 Enables Embedded Protocol Analyzer, clearing buffered data
!N1=n DN 0
Values: n = 24-character string
Default: null string
Sets directory number (DN) for channel 0. The directory number is a telephone number
assigned to the TA at subscription time by the ISDN service provider. The DN is a string
of up to 24 characters; valid characters are 09, the * character, and the # character.
!N1=n Sets the DN for the data channel
