OVERVIEW
This chapter provides information on the D IAL P LAN , including discussions
on interface configurations for the following modules:
• Dual T1/PRI (network and user terminations, for PRI and RBS)
• Dual Nx 56/64 (user termination)
• Quad BRI/U (network and user terminations)
In addition, a section is included on using the D IAL P LAN with Frame Relay
(see Connecting Packet Endpoints in Frame Relay on page 11-28).
The D IAL P LAN submenus (see Figure 11-1) set global ATLAS 550 switch
parameters as well as individual parameters for each ATLAS 550 port han-
dling a switched call. The individual ports are separated into two port
types: network and user. Network ports terminate a connection from the
Network. User ports terminate incoming calls and, in turn may be con-
nected to user equipment. Network Term on page 11-3 and User Term on page
11-6 provide clarification for these two port types. (See also Figure 11-2 on
page 11-2 for the menu structure.)
