MT90882 256 channel TDM-to-Packet Processor with Integrated TDM Switch
| Product Status - Obsolete |
|
The MT90882 is highly functional TDM to Packet bridging device. It provides a bridge between a WAN environment based on constant bit rate TDM streams and a packet domain based on Ethernet technology.
It is capable of assembling user-defined packets of TDM traffic from the WAN Access Interface and transmitting them from the Ethernet interfaces using a variety of protocols. If external processing is required (e.g., HDLC or modem termination) the traffic can be switched to a local interface using the internal TDM switch.
Features
- WAN interface, consisting of 8 input and output streams at 2.048 or 8.192 Mbps
- Up to 256 bi-directional 64 Kbps channels
- N * 64 Kbps trunking of channels across any stream and channel
- 256k by 256 k non-blocking TDM switch
- Local TDM interface, with 8 streams at 2.048, 4.096 and 8.192 Mbps
- Flexible, multi-protocol packet encapsulation
- Dual 100 Mbps 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
Typical Applications
-
Packet backplane interconnection
- Circuit Emulation over packet domain
- Internet Off-load
- Remote Access Concentrators
- H.100/H.110 extension and expansion
