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

• H.100/H.110 extension and expansion
