The SPA-2XCT3/DS0 has been a valuable addition to our network. It supports channelized T3 to DS0 connections reliably, offering excellent performance for our needs.
Reliable and fast. The SPA-2XCT3/DS0 performs flawlessly, handling T3 to DS0 connections with ease and enhancing the performance of our infrastructure.
The SPA-2XCT3/DS0 is perfect for our requirements. It provides stable, high-performance connectivity, ensuring seamless communication across our network.
We've integrated the SPA-2XCT3/DS0 into our setup, and it's provided stable and reliable performance. It's a great solution for channelized T3 connections.
The SPA-2XCT3/DS0 module is a fantastic upgrade for our system. It handles T3 connections effectively and integrates easily into our network.
The Cisco SPA-2XCT3/DS0 is a 2-port channelized T3 to DS0 Shared Port Adapter that provides two DS3 interface ports, each channelized into up to 672 individual DS0 time slots for granular voice and data deployments on supported Cisco routers.
The SPA-2XCT3/DS0 is compatible with Cisco 7200 series routers (including 7204VXR, 7206VXR, 72012, 72040) and the Cisco 7301 when installed in a supported WAN interface card slot.
Each T3 port on the SPA-2XCT3/DS0 supplies up to 672 DS0 channels, enabling high-density voice and data interconnectivity with individual timeslot access.
The adapter uses two standard female BNC connectors for DS3 coaxial cables, allowing direct connection to your service provider’s T3/DS3 network.
Yes. The SPA-2XCT3/DS0 is a hot-swappable module that can be installed or removed from the router’s WAN slot without powering down the chassis.
You need a Cisco IOS Software image with the Advanced IP Services or Enterprise Service feature set that includes channelized T3/DS0 support; no additional hardware license is required.
Yes. The SPA-2XCT3/DS0 supports per-timeslot configuration and grouping of DS0 channels for fractional T1, voice trunks, or custom data circuits.
Each channelized T3 port delivers up to 44.736 Mbps of aggregate throughput across all 672 DS0 timeslots.
Typical applications include high-density Voice over IP gateways, PBX trunking, call center interconnectivity, and DS0-based data transport in enterprise networks.
Power off the router (optional due to hot-swap), insert the module into an available WAN interface slot, secure the captive screws, attach DS3 coax cables to the BNC connectors, and power on (if needed). Then configure via CLI.
No. The adapter draws all required power from the host router chassis; no separate power connection is needed.
Use Cisco IOS commands such as 'show controllers ds3 <slot/port>' and 'show interfaces <interface-id>' to view alarms, signal status, and individual DS0 channel statistics.
Check physical layer alarms with 'show controllers ds3', verify channel-group configurations, perform loopback tests, and inspect cable continuity and framing/crc settings.
The SPA-2XCT3/DS0 provides two channelized DS3 (T3) ports with up to 672 DS0 channels per port, whereas the SPA-2T1/E1 supports two T1 or E1 ports with up to 48 DS0 channels total.
Cisco provides a limited one-year hardware warranty for the SPA-2XCT3/DS0, with options to purchase extended service contracts through Cisco SMARTnet.
You can acquire the SPA-2XCT3/DS0 from authorized Cisco resellers, distributors, or directly through Cisco’s online commerce portal.
