!C0=n Network Switch Type
Values: n = 0, 1, 2, or 5
Default: !C0=2 (International—NET3)
!C0=5 (USA—US N1-1)
Selects one of the network switch types supported by ISIHx cards. International factory
default setting is !C0=1 (Northern Telecom DMS-100). Default for USA is !C0=5 (USA—US
N1-1).
!C0=0 AT&T 5ESS
!C0=1 Northern Telecom DMS-100

!C6=n SPID 0
Values: n = 0–20-character string
Default: null string
Specifies 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
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.
!D0=n V.120 LLC Information Element
Unit: Decimal ASCII code
Values: n=0 (disable),
n=1 (enable)
Default: !D0=0 (disabled)
Some switches do not support ISDN SETUP messages that contain a LLC (Low Layer
Compatibility) Information Element (IE). When these switches receive a LLC IE in the
SETUP they immediately reject the call and then the TA reports NO CARRIER. The LLC IE
for V.120 may be disabled by using !D0=0 to avoid problems with switches that do not
support a LLC IE. The V.120 LLC IE only helps the answering TA determine the type of
digital call and various options associated with that call and so it is not necessary.
