ATM Adaption & Connectivity

Close

Metrodata’s ATM product range provide Rate, Interface and Media conversion functions for E1, T1, E2, E3, E4, DS3, STM1, OC3 leased line, fibre and copper ATM presentations. The Access processor range also provides a convergence function between a wide variety of interface types.

These products are 2-port ATM switching converters which perform physical interface conversion and rate adaption functions. For example allowing 155Mbit/s ATM equipment to interconnect over lower speed ATM or leased line services.

ATM Network Interfaces: E1, E2, E3, DS3, E4

ATM Equipment Interfaces: E3, DS3, STM-1, OC-3, including electrical and multimode and singlemode optical interfaces

These products are 2-port ATM feeder devices which allow non-ATM equipment e.g. PBX, Video Codec, to be integrated into an ATM infrastructure. For example allowing 2Mbit/s PBX equipment or 34Mbit/s broadcast quality video to interconnect across an ATM network.

Non-ATM Interfaces: E1, E2, E3, DS3

ATM Interfaces: E3, DS3, STM1, OC3, including electrical and multimode and singlemode optical interfaces

These products are 2-port ATM Network Termination Units which allow the connection of 155Mbit/s ATM equipment with multimode fibre or twisted pair copper connections to ATM services which are typically delivered via singlemode or BNC circuits. As well as a media conversion function they perform a service demarcation function, offering comprehensive operational performance statistics.

ATM Port 1: STM1 or OC3 155Mbit/s multimode or twisted pair RJ45

ATM Port 2: STM1 or OC3 155Mbit/s Singlemode Fibre (long haul or short haul) or BNC

The Metrodata Access Processor (AP) range is a modular platform designed to support the transport of multiple services. The Metrodata AP is based around a powerful ATM switch, and there are 3 basic chassis models of AP each supporting a different number of modules. The AP modules are hot swappable and can be used in any of these chassis.

The AP range has a comprehensive selection of interfaces, and can be used in a variety of ways depending on your application. It can be used to simply transport Non-ATM services such as IP, Serial, Leased Lines over incompatible infrastructure. Alternatively it can be used to multiplex and switch ATM connections.

The AP Range can transport most non-ATM services transparently with ATM used purely as the transport mechanism. It provides flexibility of interface, flexibility of bit-rate and flexibility of operation.

Non-ATM Interfaces: T1, E1, E2, E3, DS3, OC-3/STM-1, EIA530, HSSI, ECL, ASI, 10/100Mbit/s LAN

ATM Interfaces: E1, E2, E3, DS3, OC-3/STM-1, EIA530, HSSI, ASI.
