Scenario 2: Two Systems, Tandem Tie Facilities
2
Scenario 2 describes a medium-sized, mail-order company that has two locations, 
one in Chicago and one in California. This scenario includes more system details 
and fuller descriptions of business needs than do the others in this chapter. The 
various departments and staff use two MERLIN LEGEND Communications 
Systems connected by tandem T1-emulated tie trunks that provide fractional 
point-to-point service; some T1 channels are programmed for voice and others 
are programmed for data only. In this company, there is one system manager, who 
also acts as Manager of Information Systems for the company’s computer 
systems. It is designed to put networking in the context of a complete system. The 
company conducts catalog sales with supervised groups of order-takers and 
customer service representatives. It also sells to large corporate customers 
through a field sales force. 
NOTE:
It is recommended that PRI lines, rather than tie lines, be used between 
MERLIN LEGEND Communications systems in a private network that 
utilizes the Centralized Voice Mail feature. Refer to 
Table 1–1, page 1-11
 
for advantages of PRI lines.
With a view to examining networked systems in a larger context of overall 
business needs and system features, this scenario discusses the following topics:
Company Needs. General, group, and individual requirements for 
communications system and application functionality
General System Description. A summary of the equipment, features, and 
applications that meet company needs overall and specifically help certain 
work groups and individuals
Network Planning and Maintenance. A description of how the private 
network is set up and how calls are handled to fulfill the company’s 
requirements
Company Needs
2
Company needs and the solutions provided by the system fall into the following 
categories:
General. Broad concerns that affect the company as a whole and require 
basic decisions about the lines/trunks used in the system
Work Groups. Specific communications needs of groups who work 
together
Individuals. Needs of individuals, such as the system manager and off-site 
employees
 illustrates the locations and staffing.
