For each call, the switch determines which service is required
to handle it based on the number dialed and its administration
tables. The switch will then request a particular service from
the network through an ISDN message. Call-By-Call Service
Selection provides the greatest amount of efficiency in the
engineering of access facilities.
Table D-1 summarizes the access arrangements supported by the
different switch releases.

Network Requirements for Incoming Call Routing

In order to properly route calls from a public network, such as
SDN/SDDN, the switch requires information regarding the called
number. The Dial Number Identification Service (DNIS) provides
this functionality on both robbed-bit and ISDN PRI facilities. Note
that digits sent from the network must match the dial plan of the
switch in order for the switch to properly route the call.
Therefore, when provisioning a network service the requirements
for digit delivery must be specified.
