Which Cisco router platforms support the SPA-2XCT3/DS0 adapter?
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.
How many DS0 channels does each T3 port provide?
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.
What type of cable connectors are required for the SPA-2XCT3/DS0?
The adapter uses two standard female BNC connectors for DS3 coaxial cables, allowing direct connection to your service provider’s T3/DS3 network.
Is the SPA-2XCT3/DS0 hot-swappable?
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.
What Cisco IOS software license is required to operate the SPA-2XCT3/DS0?
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.
Can I configure fractional DS0 channel groups on this adapter?
Yes. The SPA-2XCT3/DS0 supports per-timeslot configuration and grouping of DS0 channels for fractional T1, voice trunks, or custom data circuits.
What is the maximum throughput per T3 port on the SPA-2XCT3/DS0?
Each channelized T3 port delivers up to 44.736 Mbps of aggregate throughput across all 672 DS0 timeslots.
What are the primary applications for the SPA-2XCT3/DS0 adapter?
Typical applications include high-density Voice over IP gateways, PBX trunking, call center interconnectivity, and DS0-based data transport in enterprise networks.
How do I install the SPA-2XCT3/DS0 in my router?
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.
Does the SPA-2XCT3/DS0 require external power?
No. The adapter draws all required power from the host router chassis; no separate power connection is needed.
