Product Review

The Cisco SPA-2CHT3-CE-ATM adapter provides efficient T3/E3 circuit emulation and ATM connectivity, supporting high-performance applications with its compatibility across Cisco XR 12000, ASR 1000, and 7600 Series Routers. With two T3 ATM ports and 10 Gigabit Ethernet, it offers versatile network integration and supports up to 2000 virtual circuits, enhancing ATM QoS with VC & VP shaping. However, its operational temperature range and power consumption may limit deployment flexibility in environments with extreme conditions or limited power availability.


The Cisco SPA-2CHT3-CE-ATM is a specialized adapter designed for T3/E3 circuit emulation and ATM, catering to a variety of high-performance network demands. This adapter is compatible with multiple Cisco router series, including the XR 12000, ASR 1000, and 7600, making it a versatile solution for network infrastructure upgrades or expansions. With its dual T3 ATM ports, it provides a reliable connection for transmitting data across networks at high speeds. Additionally, the 10 Gigabit Ethernet port type ensures fast data transfer rates, suitable for demanding applications and services. One of the standout features of the Cisco SPA-2CHT3-CE-ATM is its support for Inverse Multiplexing over ATM (IMA) and ATM User-Network Interface (UNI) versions 3.0 and 3.1, enhancing its utility in various network configurations and ensuring compatibility with a broad range of network standards. Furthermore, the adapter can handle up to 2000 virtual circuits, offering substantial capacity for data transmission and network management. Its ATM Quality of Service (QoS) support for VC and VP shaping allows for efficient traffic management, ensuring a smooth and reliable network performance. The physical specifications of this adapter include a compact design with dimensions of 0.8 inches in height, 6.75 inches in width, and 7.28 inches in depth, and it weighs just 0.75 lbs. Despite its small size, it is a powerful device with a power consumption of 20 W. It operates within a temperature range of 5 °C to 40 °C, with a storage temperature range from -40 °C to 70 °C. This wide range of operating and storage temperatures ensures that the adapter remains functional in various environmental conditions. The humidity levels for operation and storage are set from 5% to 85% and 5% to 95%, respectively, allowing it to withstand different moisture conditions without compromising its performance. Network management is facilitated through Simple Network Management Protocol (SNMP), making it easy to integrate and monitor within existing networks. The adapter also supports Online Insertion and Removal (OIR), allowing for maintenance or upgrades without significant network disruptions. This feature is particularly beneficial in environments where network uptime is critical. LED indicators on the device provide immediate visual feedback on the SPA status, per-port status, carrier and alarm conditions, active connections, and loopback tests. These indicators help in quickly diagnosing issues and monitoring the adapter's operation without the need for extensive console checks. -
