ATM Uplink Module

There are four variations of the ATM Uplink module:

• 2-port Synchronous Optical NETwork (SONET)/ Synchronous Digital Hierarchy (SDH) OC-3c/STM-1 Single Mode Fiber (SMF)
• 2-port SONET/SDH OC-3c/STM-1 MMF (MultiMode Fiber)
• 2-port SONET/SDH OC-12c/STM-4c SMF
• 2-port SONET/SDH OC-12c/STM-4c MMF

Each module has two physical interfaces that are capable of being active simultaneously.

The major features of the ATM Uplink module are:

• LANE V2 Client - with LANE 1 compatibility, supports 128 interfaces
• QoS (Quality of Service) support for UBR, nrt-VBR, rt-VBR, and CBR
• ATM UNI (User-to-Network Interface) V 3.0, 3.1 and 4.0 signaling
• RFC 1483 support
• ILMI (Integrated Local Management Interface) Version 4.0
• PNNI (Private Network - to - Network Interface) non-transit
• Link Failover
• Spanning Tree
• Load sharing

NOTE: All ATM protocols are ATM Forum standard.
