2. CPX-1000 Voice Services Platform Description
STS-1 Module
The STS-1 module consists of two cards (
Figure 2–14
) that supports
one STS-1 interface containing 672 DS0s (28 DS1s) in a single
physical interface. This interface may be connected directly to the
Class 5 Switch, or it may be routed through an external STS-1 mux
before being connected to the switch.
STS-1 Processing Card
—processor that controls the 28
DS1s within an STS-1 circuit.
STS-1 Transition Card
—provides the STS-1 interface via
Tx and Rx coaxial connections, plus a BITS timing interface.
The STS-1 card features on-board echo cancellation. If compression
is required, an Echo Cancellation and Compression card may be
added. Debug interfaces are also provided.
The STS-1 module increases the traffic capacity of the CPX over
what can otherwise be obtained by using T1 modules. When
configured for redundancy (1 + 1), these modules occupy shelf
slots 11-16 in pairs.
