Physical Components
The Dispatch Application Processor (DAP) is usually installed in a standard rack.
DAPs are usually deployed in groups (clusters) of up to 6 DAPs. DAPs and DAP-
clusters vary with age and capacity. The DAP (Figure 2-6) exists in several
configurations:
• IMP-DAP — that supports 300 EBTS sites and 45,000 users
• N-DAP — that may be a 6-DAP cluster with up to 1000 EBTS sites and
90,000 users
• T-DAP — That supports clusters 1000 EBTS sites and 180,000 users
The DAP consists of:
• Standard System Controllers
• Input Output Controllers
• Central Processing Unit
• Router Controller
• Mass Storage Devices
