The Cisco PA-MC-2T3+ Dual Multichannel T3+/DS3+ Port Adapter is a high-performance WAN interface module designed for Cisco 7200, Cisco 7300, and Cisco 7500 Series routers. Featuring two enhanced multichannel T3+/DS3+ ports, the adapter provides reliable, carrier-grade WAN connectivity for enterprise, service provider, and telecommunications networks requiring high-speed leased-line communications.
Each port supports T3/DS3 line rates of up to 45 Mbps, providing an aggregate bandwidth of up to 90 Mbps. The module supports both channelized and unchannelized T3/DS3 operation, allowing organizations to allocate bandwidth efficiently and deploy flexible WAN architectures that can adapt to changing network requirements.
The Cisco PA-MC-2T3+ supports industry-standard M23 and C-Bit Parity framing, B3ZS line coding, and multiple WAN encapsulation protocols including HDLC, PPP, and Frame Relay. These capabilities enable seamless integration with carrier networks while supporting secure and reliable point-to-point and leased-line connectivity.
Powered by Cisco IOS, the adapter supports advanced networking features such as Multilink PPP, Quality of Service (QoS), traffic management, and comprehensive network monitoring, depending on the router platform and software configuration. The integrated hardware processing architecture ensures efficient packet forwarding and dependable WAN performance for business-critical applications.
Designed as a modular plug-in port adapter, the PA-MC-2T3+ is compatible with Cisco 7200, 7300, and 7500 Series routers and can be hot-swapped on supported platforms, simplifying maintenance and reducing downtime. The module is powered directly by the host router, eliminating the need for an external power source.
Ideal for enterprise WAN connectivity, service provider networks, carrier Ethernet backhaul, branch office aggregation, high-speed leased-line access, and telecommunications infrastructure, the Cisco PA-MC-2T3+ Dual Multichannel T3+/DS3+ WAN Port Adapter delivers scalable performance, flexible bandwidth allocation, and enterprise-grade reliability for demanding WAN deployments.
