Cisco AS5300 - Universal Access Server Configuration Manual

Configuring the Cisco AS5300 Network Access
Server
This chapter describes how to configure the Cisco AS5300 network access server (NAS) to receive calls
from the Cisco 1604, Cisco 766, and remote modem users as presented in Chapter 1, "Dial Case Study
Overview".
Network Topology, Hardware, and Software Parameters
In the network topology shown in Figure 2-1, the PRI telephone number assigned to the Cisco AS5300
at the central headquarters site (hq-sanjose) is 4085551234. This number is often called the hunt group
number, which distributes calls among the available B channels. All four PRI trunks on the Cisco
AS5300 are assigned to this number by the PRI provider. The directory numbers for the remote devices
are configured on the Cisco AS5300 and then, subsequently configured on the remote devices
themselves.
The subnet 10.1.2.0 255.255.255.0 is configured on the Cisco AS5300 and is used for the loopback
interface and the local IP address pools as described in Chapter 1, "Dial Case Study Overview".

Table 2-1 provides detailed information about each end of the connection. This is the network
administrator's top-level design table and is used in conjunction with the network topology diagram
shown in Figure 2-1 for planning and organizing the network.
