Subscriber Addressing
Each SVC subscriber is identified by an ID, or address, of up to 15 digits. Subscriber
IDs are the called and calling addresses in call setup packets.
Subscribers using a public data network (PDN) must conform to the format used by
the PDN. A private network (that will not communicate with other networks) does not
need to follow the format—any or all of the digits can be used as desired, following
the guidelines in this section.
A Remote Control ID in a SmartSwitch 1800, FRX4000, FRX6000, or SmartSwitch
9000 Frame Relay Module can be used by an FRX8000 INM or NMP to take remote
control of another Netlink device on the same network. Before this can be done, a Sub-
scriber record must be created in the FRX8000 database, with the Remote Control ID
of the remote device configured as an FRX8000 Subscriber ID.
Wildcards in Subscriber Addresses
Each subscriber is assigned to an FRX8000 port, and more than one subscriber can be
assigned to one port. To eliminate the need to specify the complete ID of every
subscriber on the port, the question mark and the asterisk (* - also called “star”) can
be used as “wildcard” characters.
A question mark in an address matches any single digit. For example,
3110??????????
is any 14-digit address that begins with
3110
.
An asterisk matches any combination of digits, including none at all. For example,
3110*00
is any address that starts with
3110
and ends with
00
, including
311000
(but not
31100
—overlapping is not allowed). Note that
*
by itself is very important, because it
matches any address.
Wildcards can be combined. The address
3110??*
is any address beginning with
3110
and containing at least two more digits.
