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 E2 UNI module offers an E2 8Mbps G.703 port supporting native ATM cells, which allows the AP to connect with other ATM equipment with an E2 UNI port, either directly or via an E2 G.703 8Mbps leased line. This module can also be used as an uplink for connection to another AP chassis at the other end of an E2 G.703 8Mbps leased line.
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 E2 G.703 8Mbps interfaces with 75 ohm BNC connectors
- can be used in any AP chassis
- hot swap interface module, with configuration automatically loaded onto the replacement module
