Cisco Module NIM-2MFT-T1/E1 : Dual-Port T1/E1 Support ,
Multi-Protocol Flexibility For ISR 4000 Routers
The Cisco NIM-2MFT-T1/E1 is a high-performance network interface
module designed for ISR 4000 series routers, providing dual-port
T1/E1 connectivity with multi-protocol flexibility. Ideal for
enterprise branch offices, service providers, and legacy network
upgrades, this module ensures seamless integration of traditional
TDM (Time-Division Multiplexing) networks with modern IP-based
infrastructure.
Key Features & Benefits
✔ Dual-Port T1/E1 Support – Each module delivers two independent T1
(1.544 Mbps) or E1 (2.048 Mbps) ports, optimizing rack space and
reducing hardware costs.
✔ Multi-Protocol Flexibility – Supports CAS (Channel Associated
Signaling) and CCS (Common Channel Signaling), along with SF/ESF
(T1) and PCM30/31 (E1) framing for global compatibility.
✔ Enterprise-Grade Reliability – Features hardware-based error
detection, BERT (Bit Error Rate Test), and QoS (Quality of Service)
for mission-critical voice and data traffic.
✔ Hot-Swappable & Scalable – Easily installed in Cisco ISR 4000
series routers without downtime, supporting modular expansion.
✔ Seamless Cisco Integration – Managed via Cisco IOS XE, compatible
with SD-WAN, VPN, and NetFlow for unified network control.
