1.0 FEATURES

• High functionality, low cost implementation of

the ECTF H.100/H.110 interoperability

specifications.

• Simple to connect PCI and cPCI™ board-level

circuitry to the universally accepted CT Bus™.

• Ultra slim profiling (176-pin LQFP package).

• Up to 128 programmable connections (64

transmit and 64 receive) to any of the 4096 time-

slots on the H.100/H.110 CT Bus.

• 8-channel stream-to-stream switching for data

stream connections at variable rates.

• Implementation of all compatibility signals for

complete interoperability with existing 4 MHz

SCbus™, 8 MHz SCbus, 2 MHz MVIP-90™

devices, and H-MVIP™.

• Master PLL meets AT&T 62411 MTIE and jitter

attenuation requirements to provides reliable

clock synchronization for network-grade

connection to digital network interfaces.

• Supports all H.100/H.110 CT Bus clock fallback

features.

• Choice of constant or minimum switching

delay on a per time-slot basis.

• 3.3 V I/O with 5 V tolerant input.

• Supports multiplexed and nonmultiplexed

address/data bus modes for both Intel and

Motorola microprocessors.

• Supports CT Bus optional message channel

interface, for both H.100 (PCI) and H.110 (cPCI)

applications.

• Supports a variety of framing formats via a

configurable local bus.

• Efficient microprocessor interface access to

Local and CT Bus data streams through direct

parallel access to/from transmit and receive

switch.

• Direct Parallel Access to/from Transmit and

Receive switch allows efficient microprocessor

interface access to local and CT Bus data

streams.

1.1 Applications

• Low- to medium-density computer telephony hardware (PCI and cPCI platforms)

• Enhanced service platforms

• Private branch exchanges (PBXs)

• Wireless base stations

• Internet telephony systems

• Digital trunking equipment
