Table 2–24, page 2-93 is an overview of how the system managers set up their
systems for internetwork use of PSTN facilities. To avoid repetition, details are not
provided. As you review the table, keep the following points in mind:
■ Network calls going out to the PSTN are not routed through Systems N
and O. Even when a System O caller needs to reach the 303 area code
(rare), he or she uses PSTN trunks originating at System A. The
ground-start lines/trunks connected to System N are used for local calling
by System N users. Because of volume pricing benefits for OUTWATS
services, System O and System A users make toll calls only via System A,
even when calling a toll number in Colorado.
■ On System N support agents use a PassageWay Telephony Services
application that receives calls on PRI dial-plan routed facilities connected
to System A and directed to their calling group, Ext. 4400. This
arrangement allows them to receive screen pop of customer database
information based on the ANI calling party number. Because this calling
group number is not included in the System A non-local dial plan, System A
users cannot make intersystem calls to the group. They can reach calling
group members by dialing their individual extension numbers.
■ Customer service agents on System N receive customer calls via
T1-emulated DID lines connected to System A and routed to their calling
group, Extension 4500. Non-local users do not usually call this group; if
they need to reach an agent, they call the agent’s individual extension.
