Access Network Design
The Access Network Design module provides IXC Frame Relay pricing and access design. IXC Frame Relay pricing supports AT&T, MCI, Sprint, and WorldCom, with customizable Frame Relay tariffs. Access designs range from simple homing of location to backbone MUX sites to secondary
concentration homing designs.
Direct Location-To-MUX Homing
Access design optimally homes locations to MUX sites by minimizing the access transmission costs. The program is able to select the optimal backbone MUX locations from a MUX candidate list provided by the user, homing locations based on each locations traffic requirement into the
backbone cloud.
Secondary Concentration
To further reduce network costs, Access Network Design supports two-level concentrations. Rather than home to a switch directly, offnet circuits may home to lower-level concentrator sites first. The circuits are aggregated at the lower-level concentrator sites before being carried to the backbone switches. The lower-level concentrator sites may be customer locations, Interexchange Carrier Points of Presence (IXC POP), or Local Exchange Carrier (LEC) wire centers, using LEC Frame Relay services or T1 Channel Banks. The program can select the optimal concentrator sites from a list of
user-supplied candidates, or program determined candidates.
Once the optimal concentrator sites are selected and the locations homed, backbone designs can then be performed and analyzed through the
backbone design module.
Customizations
Customizations for more sophisticated access network design features, such as diversity constraints and switch selection, can be negotiated. An example is the ability to handle the Microwave Drop and Insert capability of analog circuits. The drop and insert points (DIP) are candidate homing points for the offnet analog voice circuits. Analog circuits can terminate at the DIPS, and then ride on the microwave analog circuits to the backbone nodes.
