OVERVIEW

The SC2000 is a custom VLSI circuit optimized for use in the call processing environment. The SC2000 provides a cost-effective means of implementing the interface between a high speed internal TDM bus and an external (expansion) TDM bus. Internal buffering allows the exchange of data between TDM buses of different speeds and architectures.

FEATURES

• Multi-time slot switching capability for N x 64K channels (N = 1 to 32).

• Architecture optimized for the call processing environment: SCSA TM, PEBTM, or MVIPTM compatible.

• Two software selectable expansion bus formats:

• SCbusTM /ST-BUSTM

• PEB

• Two software selectable local bus formats:

• ST-BUS

• PEB

• Enhanced input hysteresis threshold.

• 32 x 2048 channel switch

• Serial or parallel access to the SCbus.

• Internal support for SCbus clock fallback

• Built-in SCbus message bus interface

• Supports both Intel® and Motorola® processor interfaces

• 68-pin PLCC package

• 5v CMOS technology
