Cisco 2800/3800 Series T3/E3 ATM Network Module

Handle Increased Traffic with Low Latency

The Cisco T3/E3 ATM Network Module provides ATM WAN connectivity for enterprise regional and branch office connectivity on the Cisco 2800 and 3800 Series Integrated Services Routers. This combined T3/E3 ATM network module provides an ATM connection of either 44 Mbps for DS3/T3, or 34 Mbps for E3 using standard 75-ohm BNC connectors. Support is provided for the AAL5 framing standard, as well as ATM Traffic Management support for Unspecified Bit Rate (UBR), UBR+ (For switched virtual circuits [SVCs] only), Variable Bit Rate real-time (VBR-rt), VBR non-real-time (VBR-nrt), constant bit rate (CBR), and available bit rate (ABR) classes of traffic.

T3/E3 WAN access enables your network to carry high volumes of data and multimedia content, while providing low latency for voice over IP (VoIP).
