FACILITY DESCRIPTION
Faktaansvarig - Subject responsible
Destination Number Group. All possible carriers
are proposed when John has dialled a Route Ac-
cess Code. When the user has entered a direc-
tory number of a single trunk, Least Cost Routing
proposes just those carriers that can be reached
via the particular trunk.
Further use of the output
• The cost analysis calculates the predicted cost
for possible carriers.
Example
The Destination Number Group for the United States is
„111“. The carriers „PTT“ and „Ferrari“ support this
Destination Number Group.
Cost Analysis
Least Cost Routing starts with the calculation of the
predicted cost after a possible carrier has been
determined.
Inputs, Databases and Outputs
This chapter shows the information required for the
Cost Analysis and provides a short description of the
output and its further use.
Input for the analysis
• Destination Number Group (output of the num-
ber analysis)
• Possible carriers (output of the carrier analysis)
• Date
• Time of the day
General database for the analysis
• Predicted call duration [2035]
• Daytype table [Maintenance /system /day types]
(3 types: dt1 = WORKDAY, dt2 = PARTIAL
WORKDAY, dt3 = HOLIDAY)
• Exception Days Table [Maintenance /system /ex-
ception days]
Carrier-specific database for the analysis
• General Call Cost Profile [8440]
• Cost Time Scheme (list price) [8445].
• Cost Time Scheme (special price) [8450]. This
table is useful if tenants have special agree-
ments with the network provider.
• The billing principle [8403] used for the calcula-
tion of the predicted cost. You may choose be-
tween „Pulses“ and „Duration“.
• Pulse Cost Level Table (list price) [8455] if the bil-
ling principle is „Pulse“.
• Pulse Cost Level Table (special price) [8460] if
the billing principle is „Pulse“ and tenants have
special agreements with the network provider.
• Duration Cost Level Table (list price) [8465] if the
billing principle is „Duration“.
• Duration Cost Level Table (special price) [8470]
if the billing principle is „Duration“ and tenants
have special agreements with the network provi-
der.
Carrier and tenant-specific database for the analysis
• Tenant-Specific Call Cost Profile [8428] if tenants
have special agreements with a carrier.
• Cost per metering pulse [8423] if the billing prin-
ciple is „Pulse“.
• Discount factor [8425] if the billing principle is
„Duration“.
Output of the analysis
The result of the analysis is a breakdown of costs of
the possible carriers.
Further use of the output
• The breakdown of costs is the input for the carri-
er selection.
The Designers’ Way of Thinking…
A table is the most popular way to arrange numbers.
Yes, there is no doubt about it. But tables have some
disadvantages. A table is composed of only three
dimensions: lines, columns and values. A table is as
flat as a piece of paper.
