International Direct Distance Dialed calls generally consist of an international 
access code, a country code, and a national number. Both codes may vary in 
length. DEFINITY ECS support for International Direct Distance Dialed calls elim-
inates any restriction on the grouping and format of digits on Automatic Route 
Selection numbers. Call routing is determined by the digits and the length of the 
dialed number.
Multinational World Class Automatic Alternate Routing allows the Automatic Alter-
nate Routing number (Electronic Tandem Network number) to be any number of 
digits in length.
Digit conversion can be used to reroute numbers, initially dialed to use Automatic 
Route Selection, to be converted to use Automatic Alternate Routing and vice 
versa. This utility can analyses a maximum of 18 digits. In this way, destinations 
in a customer’s network can be called using the public network number. This fea-
ture can also be used to reroute certain Direct Distance Dialed destinations to 
specified alternate destinations (such as intercept, attendant, or another Direct 
Distance Dialed number).
Network Management Features
DEFINITY ECS has a variety of features that enable you to manage your network 
resources effectively. Here are just a few examples of DEFINITY ECS features 
that can be used to manage your network — Time of Day Routing, Automatic 
Route Selection, Automatic Alternate Routing, Additional Network Feature Path 
Replacement, Look Ahead Routing, Subnetwork Trunking, Generalized Route 
Selection, Facility Restriction Level, Bearer Capacity Class, Remote Network 
Access, Public Network Call Priority, and Authorization Codes.
Time of Day Routing
Time of Day Routing allows you to select the most economical routing of Auto-
matic Route Selection and Automatic Alternate Routing calls based on the time of 
day and week a call is made.
With Time of Day Routing, your company can take advantage of lower calling 
rates during specific times. If your company has locations in different time zones, 
you can maximize the use of your public or private network facilities by utilizing 
those in the location that has the lowest calling rates at the particular time a call is 
made. You can also use this feature to change the routing patterns when an 
office is closed and to eliminate unauthorized calls. You can set up eight sepa-
rate time of day charts to control routing at different times of the day.
