Routing Table Structure; Session Router Configuration Task List - Patton electronics SmartNode Series Software Configuration Manual

SmartWare Software Configuration Guide
Due to the tree search algorithm implemented in the session router very large routing tables can be scanned
very quickly with minimal impact on the call setup delay. The SmartWare session router supports the following
routing criteria:
• Calling Party Number (CnPN); also called Source-Nr, A-Nr, MSN, DDI or CLIP
• Called Party Number (CdPN); also called Destination-Nr or B-Nr
• ISDN Bearer Capability; also called ISDN Service or information transfer capability (ITC)
• Day of Week; Mon–Sun
• Time of Day; hour:minute
• Date; year/month/day

Routing table structure

Every routing table has the same general format:
type <name> {<key>|default} {dest-table <dst-name> | dest-interface <dst-name> | none} [<function>]
Identifies the type of the table according to the routing criteria
type
<name> Is a unique name identifying the table. Use "speaking" names
<key> Is the matching key , according to the routing criteria. The Session Router reads through the
table to find the best matching key. Having found one, it examines the other elements in that
row. The default matching key is followed if no other row matches. If no default entry is config-
ured and no other entry matches, the call is routed to the fallback destination configured on
the interface.
dest-table Specifies the routing table (name) to be used as the next in the decision tree. The call setup is
forwarded to the table and matched against the keys.
dest-interface Specifies the CS interface (name) to be used as the outgoing interface.
<function> Is the name of a number manipulation function to be executed before the call setup is for-
warded to the next routing table or the destination interface
Note
To support broadcast features the routing table needs a default entry!
Session router configuration task list
To configure the session router, perform the tasks in the following sections and in order as listed below.
• Map out the goals for the session router (see
• Configure the entry table on circuit interfaces (see

Session router configuration task list

The session router allows you to solve practically any call routing
and number manipulation requirement that you may have. The
Session Router is very flexible in allowing the construction of
decision trees based on linked routing tables. However you
should take care not to use too many tables and an over-elabo-
rate structure. The configuration may become large and difficult
to manage. For complex configurations we recommend offline
editing and configuration downloads.
