1000-A2-GN22-00 2. CPX-1000 Voice Services Platform Description
The capacity of the CPX shelf configured with either T1 modules
depends on the shelf configuration and the concentration and
redundancy options selected.
A CPX 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.
CPX-1000
Operation
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 2–2 illustrates this functionality when providing access to
the PSTN via T1, using the 12-port T1 ECAC module.
