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.

Class 5 switch into cell-based ATM format.

Capacity
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.
