R0106-HP MSR Router Series Layer 2 - WAN Command Reference(V7)

130
Parameters
check-index: Specifies a called-number verification index in the range of 1 to 3.
called-party-number: Specifies an acceptable called number. You can include a colon-separated
subaddress when you specify the called number, for example, 66668888:13525. The value must be a
case-sensitive string of 1 to 40 characters.
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 66668888:1352 5 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 bytes for CE1/PRI and CT1/PRI interfaces and 1 byte for BRI interfaces.

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 this command only when no calls are present on the ISDN interface.
Examples
# Set the call reference length to 1 byte on the PRI interface Serial 2/3/0:15.
<Sysname> system-view
[Sysname] interface serial 2/3/0:15
