!C0=n Network Switch Type
Values:n = 0, 1, or 5
Default:
!C0=1 (Northern Telecom DMS-100)
Use the !C0= command to select one of the seven network switch types supported by
the ISIHI-2S. Factory default setting is !C0=1 (Northern Telecom DMS-100).
!C0=0 AT&T 5ESS
!C0=1 Northern Telecom DMS-100
!C0=2 NET3 (Euro ISDN)
!C0=5 US NI-1
!C6=n SPID 0
Values: n = 0–20-character string
Default: null string
Use the !C6= command to specify the channel 0 service profile identifier (SPID) that the
ISDN service provider assigned at subscription time. The data 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.)
*!C6=n SPID 1
Values:n = 0- to 20-character string
Default: null string
Use the *!C6= command to specify 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)
Use to set 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. 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 can also use the
!D3= command 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
