Errors
The following example resets the value of the CUD for the SU $X25P1.#TERM:
-> ALTER SU $x25p1.#TERM, CUD RESET
The following example alters the value of the CUD for the SU $X25P1.#TERM2:
-> ALTER SU $x25p1.#term2, CUD “0123456789abcdef”
Hexadecimal characters beyond 9 can be either uppercase or lowercase letters.
If the called network (REMOTENET) does not require a port number in the CUD, you
can set or alter the CUD field of a subdevice with the ADD SU and ALTER SU
commands.
Errors
SCF error 511 is returned if the SU has a REMOTENET of X25UD, DATAPAC, DDXP,
or UNINET.
If REMOTENET is not specified, the NETID values are used. With no REMOTENET,
the NETID values of X25UD, DATAPAC, DDXP, or UNINET are incompatible with the
specification of a CUD string.
The following attribute name and value can be used for an X25AM subdevice (SU)
object:
CUD { “hex string”| RESET }
You can specify the CUD as a hexadecimal string with a length of 0 to 32 characters by
using the ADD SU or ALTER SU command. (Two hexadecimal characters are
equivalent to 1 byte in the CUD. Thus, a maximum of 32 hexadecimal characters is
equivalent to a maximum of 16 bytes.)
A maximum value of 32 hexadecimal characters can be specified for PTP subdevices.
The maximum value that can be specified for ITI subdevices is 24 characters (12 bytes
in the CUD field). The first 4 bytes are reserved for the protocol ID.
If the hexadecimal string exceeds the maximum length, SCF issues the following error
message:
SCF E20084 Quoted string can be no more than 32 characters
long
If nonhexadecimal characters are specified in the string, SCF issues the following error
message:
X25AM E00507 Invalid value: CUD for object name
Using the ALTER SU command, you can specify the RESET option to delete the CUD
field from the SU. The RESET value means no call user data is present in CUD field.
