A CPX installation is scalable: first by populating an individual shelf, then by adding additional shelves. Each CPX shelf occupies 12 RU (21 inches high) and is 17 inches deep.

Using optional mounting brackets, the shelf can be installed in 19-inch EIA310, Bell Wide, Bell Narrow, and NEBS2000 racks. Reversible mounting brackets allow installation in 23-inch racks.

Asingle CPX-1000 can manage than 18,800 subscriber telephone lines (at 9:1 concentration ratios) on a voice-over-broadband network, including:

Circuit-to-packetconversion—converts DS0s from the Class 5 switch into cell-based ATM format.

Routing—routes cells to and from IADs at subscriber locations.

Call administration—manages call-control signaling to both the Class 5 switch and the IADs.

Traffic management—monitors the connection over the access network to each end user.

Concentration management—supports line

￿concentration levels up to 40:1.

System and Service Administration—acts as the administrative platform for managing voice-over-packet services.

The CPX supports up to 4,000 IADs, and supports two types of T1 modules, which may be used interchangeably: The Octal T1 module provides 8 T1 ports, and up to 6 modules may be placed in the CPX. Echo cancellation or echo cancellation and compression is provided on separate cards. The 12-port T1 ECAC module provides 12 T1 ports, and up to 7 modules may be placed in the CPX. Also, echo cancellation and compression is provided directly onboard, eliminating the need for separate EC or ECAC cards.

The CPX also supports two types of STS-1 cards, which may be used interchangeably. Up to 6 STS-1 cards may be installed in each CPX. The STS-1 module does not provide onboard echo cancellation or compression—you must use separate modules. The STS-1 ECAC module includes onboard echo cancellation and compression, eliminating the need for separate EC or ECAC cards.
