描述 Description

The MT9088x is a family of highly functional TDM to Packet bridging devices. It provides a bridge between a WAN environment based on constant bit rate TDM streams and a packet domain based on Ethernet technology.

特性 Features

? WAN interface, consisting of 32 input and output streams at 2.048 or 8.192 Mbs

? Up to 1024 bi-directional 64 Kbs channels

? N * 64 Kbs trunking of channels across any stream and channel

? 1 K by 1 K non-blocking TDM switch

? Local TDM interface, with 32 streams at 2.048, 4.096 and 8.192 Mbs

? Flexible, multi-protocol packet encapsulation

? Dual 100 Mbs MII interfaces for redundancy or for load balancing

? Quality of service features, including weighted fair queuing, strict priority and queue size limit thresholds

? High performance 33 MHz / 66 MHz 32 bit PCI bus

? Integral Stratum 4E PLL for synchronisation to the

TDM domain

? Power consumption of less than 0.75 W

Applications

? Packet backplane interconnection

? Circuit Emulation over packet domain

? Internet Off-load

? Remote Access Concentrators
