Overview
ATM Uplink Module Overview
The ATM (Asynchronous Transfer Mode) Uplink module provides
LAN Emulation (LANE) or RFC 1483 connectivity over an AT
network. The module comes in four variants:
■ 2-port SONET (Synchronous Optical NETwork)/SDH
(Synchronous Digital Hierarchy) OC-3c/STM-1 SMF (Single
Mode Fiber)
■ 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 multiple physical interfaces capable of being
simultaneously active.
Table 1-1 lists the modules wavelengths.
Table 1-1. Wavelength
The major features of the ATM Uplink module are:
■ LANE V2 Client - with LANE 1 compatibility, supports up to
128 switch ports
■ QoS (Quality of Service) support for Unspecified Bit Rate
(UBR), non real-time Variable Bit Rate (nrt-VBR), real-time
Variable Bit Rate (rt-VBR), and Constant Bit Rate (CBR)
