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.
