T
erminal Adapter
*!D3=n TEI 1
Values:n = 0–63, 240 (auto), 241 (disable)
Default:
*!D3=240 (Auto TEI)
Use the *!D3= command to set the ISIHI-2S’s 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
Use to display the ISIHI-2S’s current DN, SPID, TEI, Data protocol, and switch type.
!L Displays the current network configuration
>Dn Embedded Protocol Analyzer
Values: 0, 1, 2, 3, 4, 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 Display B-channel traffic, decoded as V.120
>D1
Display D-channel traffic, decoding layers 2 and 3 (Q.921 and Q.931)
>D2 Display D-channel traffic, decoding layer 2 only (Q.921)
>D3 Display D-channel traffic, decoding layer 3 only (Q.931)
>D4 Display B-channel traffic, decoded as X.75
>D5 Display async PPP data
>D6
Display sync PPP data
>D98 Disable Embedded Protocol Analyzer, buffered data unchanged
>D99 Enable Embedded Protocol Analyzer, clearing buffered data
!N1=n DN 0
Values: n = 24-character string
Default: null string
Sets the 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
