APX EIA530 UNI Interface Module

The APX UNI interface modules enable connection to ATM services, either as network or switch ports, or are used as trunk ports for non-ATM applications. Each UNI modules provide a single ATM interface port, with the range being standards compliant and covering all standard Telecom data rates.

The APX EIA530 UNI module offers an EIA530 serial port supporting native ATM cells, which can operate asymmetrically at up to 20Mbps. This module allows the AP to connect with other ATM equipment via an EIA530 circuit (e.g. a satellite link, or an encrypted serial link). This module offers an EIA530 DTE interface which can connect directly to an EIA530 satellite modem or an EIA530 encrypter, thereby offering a flexible bandwidth ATM over serial service (e.g. ATM over satellite).

Each UNI module performs physical layer and ATM layer functions including framing, alarm processing and cell delineation. Flexible clocking options remove network synchronisation problems. Status LED's are provided to indicate that real traffic is passing across the ATM interface.

Management and configuration of this module is achieved via the simple menu driven user interface. Extensive statistics and status information are gathered at all layers and are available to the user interface as a diagnostic aid. OAM alarm and loopback functions are supported as per UNI 3.1

Additionally SNMP Traps may be generated to indicate Link Up/Down. These modules can be "Hot Swapped" to ease maintenance, with replacement modules recovering immediately without further configuration.

This module has the following features:

• standards compliant EIA530 DTE interface with 25-way male D-type
• operates asymmetrically at up to 20Mbps in each direction
• can be used in any AP chassis
• hot swap interface module, with configuration automatically loaded onto the replacement module

Applications supported:

• ATM over satellite (including asymmetric services)
  
• ATM over serial (including encrypted links)
