2 Call-Handling Scenarios
Network Configuration Scenarios
System Manager. The system manager manages one remote system
(System D) and one on-site system. The system manager accesses
System D by dialing its Remote Access code, which is included in the non-
local dial plan. For security reasons, she changes her barrier code two or
three times a week. The system manager has an MLX-20L telephone and
uses System Programming and Maintenance (SPM) for the on-site and
remote systems. The system manager has a dedicated modem to ensure
immediate access to the remote system. Her PC is directly connected to
the on-site system.
To help with her own assessments of facilities usage, the system manager
uses the system's MERLIN LEGEND Reporter application. Working closely
with customer service and sales supervisors, she analyzes the
effectiveness of the system's facilities during peak and off-peak incoming
calling periods. She ensures that customer service and order-taking agents
understand how to get the most from the lines/trunks that the company
has. MERLIN LEGEND Reporter helps managers balance staffing, staff
training, and facilities needs to serve customers effectively and efficiently.
Network Planning
In this sample scenario, the two systems are linked in a private network using T1
tandem tie trunks that support fractional point-to-point use. Some channels are
dedicated to voice traffic, emulating analog tie trunks, and some are dedicated to
T1 Switched 56 data.

trunks for this company. A few extensions are shown to demonstrate how calls are
handled and how they display for call recipients at different types of extension
equipment. Similarly, sample PSTN facilities are shown in order to illustrate
routing when non-local callers use them or when outside calls are transferred or
routed across the network.
Non-Local Dial Plans and Facilities Planning
This section shows how non-local dial plans, switch identifiers, UDP routing, ARS
routing, and remote access are set up for each system. Not all details are
provided for all facilities and extensions.
Table 2–8, page 2–42
routes for pooled facilities when people in one system call people at non-local dial
plan extensions. Pools of T1 Switched 56 channels are reserved for video and
data calls, and intersystem 2B data calls are supported at 112 kbps. At
headquarters, executives conduct videoconferences over PSTN facilities at 128
kbps.
