Routing for Outside Calls
2
This topic examines routing for hypothetical outside calls, to show how the system 
manager in Scenario 2 maximizes cost benefits from the private network. As you 
study the example call routes in 
, review the general setup 
as described in 
 and 
.
Note the following facts about routing for outside calls in this scenario:
A PRI dial-plan routed call can be routed across the private network to a 
telephone extension. However, even if ANI information is available, it 
cannot be displayed at the recipient’s extension. An example is not 
included, but the display would show information about the tandem tie 
trunk only, for example: 
7,(75.
Remote access callers to one system can dial non-local extension 
numbers.
From System C at headquarters, 2B data calls made over the outside PRI 
facility can achieve a higher data rate, 128 kbps, than intersystem video 
calls, which are routed over T1 data tie channels at 112 kbps.
PassageWay Telephony Services clients receive screen pop on incoming 
customer calls that they receive on outside PRI facilities, but they do not 
receive screen pop on those rare occasions when calls are transferred 
from headquarters in Chicago.
