CPX-1000 Operation

The capacity of the CPX shelf configured with either T1 modules depends on the shelf configuration and the concentration and redundancy options selected.

ACPX shelf using either STS-1 or 12-port T1 card with ATM OC-3 can support over 2,000 simultaneous calls and 16,000 subscriber lines (8:1 concentration).

Carriers can upgrade the CPX network by adding additional CPX-1000s, all of which can be managed by a single JetVision workstation.

Call control, circuit-packet switching, network interfaces, provisioning, and management, are divided into four basic functional blocks:

Management processing (MP)

Call Processing (CP)

PSTN interface (T1 or STS-1)

￿Packet interface

Figure 2–2illustrates this functionality when providing access to the PSTN via T1, using the 12-port T1 ECAC module.
