The ATM OC-3 network module supports the ATM forum standard ATM Adaptation Layer 5 (AAL5) with the following ATM Quality of Service (QoS) traffic classes: Unspecified Bit Rate (UBR), UBR+, real-time Variable Bit Rate (VBR-rt), non-real-time VBR (VBR-nrt), Available Bit Rate (ABR), and Constant Bit Rate (CBR). Voice over IP (VoIP) and H.323 over ATM is supported over the WAN using the currently available onboard voice Digital Signal Processors (DSPs), analog voice and fax network modules, and voice interface cards.
The network module has modular optics supporting the Cisco Pluggable Optical Modules (POMs) and Cisco Small Form-Factor Pluggables (SFPs), simplifying the selection of network modules from six offerings to one. The SFPs support STM-1 framing standards over multimode, single-mode intermediate-reach, and single-mode long-reach fiber-optic interfaces. The module is a single-port module with LC-type connector. The single-mode SFPs combined with the ATM network module provide high-speed trunking for users with access to a fiber WAN, whereas multimode is ideal for connecting high-speed servers, switches, or hubs equipped with OC-3/STM-1 fiber connections.
