Attributes for SNAX/XF and SNAX/APN
SNAX/XF and SNAX/APN Configuration and Management Manual—425836-006
14-12
CALLADDR - for SNAX/XF Only
LUs, or if the PU is a switched floating PU, the BINDTABLE attribute value must be
specified in the ADD LU or ALTER LU command.
If a BINDTABLE parameter is specified in an ESS table entry, it overrides the
parameter specified in the ADD command.
CALLADDR - for SNAX/XF Only
CALLADDR specifies the remote DTE network address of a PU on an X.25 line.
This attribute is valid only for PUs that use X.25 lines or Token-Ring lines. For incoming
calls, it is used for network address validation. For outgoing calls, it is used as the
remote network address to be called.
For permanently subordinated PUs used for dial-in connections, this attribute is
optional. If, however, the CALLVALIDATE attribute for the PU specifies CALLADDR,
this attribute is no longer optional, and you must specify it.
For switched floating PUs and for PUs subordinate to a switched line, you can specify
one of the following attribute combinations:

CALLVALIDATE and either CALLADDR or CONNID attribute

CALLVALIDATE and both CALLADDR and CONNID attributes

PUIDBLK and PUIDNUM attributes

CALLVALIDATE, CALLADDR, CONNID, PUIDBLK, and PUIDNUM attributes
SNAX/XF uses the CALLADDR specification when it attempts to match the calling
address provided by dial-in users with the corresponding switched floating PU or PU
subordinate to a switched line. If a match is found for a switched floating PU, the call-in
operation continues, and the PU is assigned to the line on which the call was received.
Otherwise, SNAX/XF rejects the call unless there are PUs configured that require no
validation.
The CALLADDR attribute can be removed through the ALTER PU command by
specifying a null string (" ") as the value.
Default: None
Value: String of 1-15 numeric characters (0-9) or 1-15 hexadecimal characters
(0-9 and A-F)
Objects: PU
Note. When using SNAX/CM with SNAX/XF, you can duplicate CALLADDR values on different
lines with multiple ports. The same values can be specified for a switched floating PU as were
specified for a PU permanently subordinated to a switched line using either a single port or
multiple ports. This change allows a PU access to several SNAX/XF lines to support larger
switched networks.
