Usage guidelines
Called-number verification enables an ISDN interface to accept only calls placed to specific called
numbers. You can configure the ISDN interface to verify only the called number or both the called
number and the called subaddress. The ISDN interface will accept a call only if the called-number
information matches one entry in the list of acceptable called numbers.
Examples
# Add
66668888
:
13525
to the list of acceptable called-numbers on BRI 2/4/0.
<Sysname> system-view
[Sysname] interface bri 2/4/0
[Sysname-Bri2/4/0] isdn check-called-number 1 66668888:13525
isdn crlength
Use
isdn crlength
to set the length of the call reference for calls placed on an ISDN interface.
Use
undo isdn crlength
to restore the default.
Syntax
isdn crlength call-reference-length
undo isdn crlength
Default
The call reference length is 2 by tes for CE1/PRI and C T1/PRI interfaces and 1 by te for BRI
interfaces.
Views

Predefined user roles

Parameters
call-reference-length
: Specifies an ISDN call reference length, in bytes. Available values include 1
and 2.
Usage guidelines
Call reference is a sequence number that identifies a call. A call reference can be reused after it is
released when its associated call is released.
When the router is connected to a peer device that cannot recognize the call reference length, you
must configure the router with the same call reference length as the peer device.
You can configure the command only when no calls are present on the ISDN interface.
Examples
# Set the call reference length to 1 byte on PRI interface Serial 2/3/0:15.
<Sysname> system-view
[Sysname] interface serial 2/3/0:15
[Sysname-Serial2/3/0:15] isdn crlength 1
isdn ignore connect-ack
Use
isdn ignore connect-ack
to enable ISDN to enter the ACTIVE state without an
acknowledgment after it sends or receives a CONNECT request.
