Product Overview
The C8300-RM-4PT-2R= is a Cisco 8000 Series Quad-Port T1/E1 Route Module designed for Cisco 8300 ISR routers. This modular component adds four T1/E1 interfaces to the chassis, enabling enterprises to integrate legacy circuits (e.g., PBX, SCADA) into modern SD-WAN or hybrid WAN architectures without compromising rack space or scalability.
Key Technical Specifications
- Interfaces: 4x T1/E1 ports with RJ-48C connectors, supporting 1.544 Mbps (T1) or 2.048 Mbps (E1) speeds.
- Compatibility: Plug-and-play installation in Cisco 8300 Series ISR chassis (e.g., C8300-2N2S-6T, C8300-1N1S-4T2X).
- Redundancy: Dual-router mode (2R) for failover support in high-availability deployments.
- Software: Managed via Cisco IOS XE SD-WAN with vManage integration for unified policy enforcement.
Addressing Critical User Concerns
Q: Why add T1/E1 ports to a modern SD-WAN router?
Many enterprises still rely on legacy T1 circuits for PBX telephony, ATM transactions, or industrial control systems. This module allows gradual migration to SD-WAN while preserving existing infrastructure investments.
Q: How does dual-router mode (2R) improve uptime?
The 2R designation enables stateful switchover (SSO) between two routers, reducing downtime to sub-second levels during hardware failures or maintenance.
Q: Can it coexist with 10G/5G interfaces in the same chassis?
Yes. The 8300 chassis supports simultaneous use of this module and 10G NIMs, letting traffic from legacy T1 systems and high-speed SD-WAN underlays share the same router.
Deployment Scenarios
- Financial Branches: Securely process card transactions over T1 while routing cloud apps via SD-WAN.
- Manufacturing: Connect PLCs/SCADA systems via T1 and prioritize IoT data with Cisco AVC (Application Visibility and Control).
- Telecom Edge: Aggregate legacy voice traffic from PBX systems onto MPLS or hybrid WAN backbones.

Why This Module Embodies Cisco’s Hybrid WAN Philosophy
In an era where “legacy” is often mislabeled as “obsolete,” the C8300-RM-4PT-2R= stands out by bridging decades-old infrastructure with cloud-native agility. Its ability to modernize networks incrementally—without forcing costly rip-and-replace projects—makes it indispensable for industries where uptime and continuity trump hype-driven upgrades. For teams navigating the messy reality of digital transition, this module is less an accessory and more a lifeline.
