Business scenario: A global retail chain deploys the Cisco NIM-4MFT-T1/E1 4-port module in branch office routers to aggregate four T1/E1 circuits carrying SIP voice, POS transaction data and video traffic over an MPLS backbone. Outcome: 30% reduction in leased‐line costs, centralized provisioning of clear-channel data channels and end-to-end QoS enforcement for crystal-clear voice across 75 locations.
Technical scenario: A regional power utility uses the NIM-4MFT-T1/E1 module to terminate four E1 trunks for simultaneous SCADA telemetry streams and 24/7 emergency voice dispatch. Outcome: Hitless failover with sub-second recovery, strict clock synchronization for reliable grid monitoring, compliance with NERC CIP standards and zero packet loss on critical control channels.
Business scenario: A Tier-1 service provider integrates Cisco ISR routers equipped with NIM-4MFT-T1/E1 modules to aggregate four multi-tenant T1/E1 voice trunks for hosted PBX and wholesale SIP interconnect. Outcome: Dynamic DS0 channel allocation, 99.999% uptime with in-service firmware upgrades, rapid trunk scaling and premium SLA-backed voice quality for enterprise customers.

The Cisco NIM-4MFT-T1/E1 is a 4-port Multiflex Trunk module that delivers simultaneous voice and clear-channel data service over T1 or E1 interfaces.
This module supports four independent T1 or E1 ports, each configurable for voice, fax or clear-channel data.
Yes. Each port can be individually configured for T1 (1.544 Mbps) or E1 (2.048 Mbps) operation.
Yes. It supports both voice (CAS, PRI) and clear-channel data on all four ports, enabling concurrent voice and data transmission.
This NIM module is compatible with Cisco ISR 4000 Series and select 2900/3900 Series routers; refer to Cisco’s compatibility matrix for exact model support.
It supports synchronous applications such as ISDN PRI, Frame Relay, dedicated leased line, SCADA and other fixed-bandwidth data services.
No. You must power down the router before installing or removing the NIM-4MFT-T1/E1 module.
Power off the router, insert the module into an available NIM slot, secure the retaining screws, then power on and verify with the ‘show controllers t1’ or ‘show controllers e1’ command.
Configure the interface with ‘interface serial <slot>/<port>:23’, set framing and line code (e.g., ‘framing esf’, ‘linecode ami’), then assign IP or dial-peer settings.
Use ‘show controllers t1 <interface>’ or ‘show controllers e1 <interface>’ to display status, alarm conditions, CRC errors and line statistics.
It delivers up to 8.192 Mbps aggregate throughput, carrier-grade reliability, flexible voice/data mixing and centralized management via Cisco IOS.
Yes. It supports channelized T1/E1 (DS0 timeslots for CAS/PRI) and unchannelized clear-channel data.
Operating temperature: 0 to 40 °C, storage: –40 to 70 °C, humidity: 5 %–85 % non-condensing, per NEBS Level 3 guidelines.
Supports Cisco IOS voice features (MGCP, H.323), Frame Relay, PPP, HDLC, multiprotocol routing, QoS and security services.
The NIM-4MFT-T1/E1 includes a limited lifetime hardware warranty when purchased with a Cisco service contract for software updates and technical assistance.
Check physical cabling and framing/linecode settings, review ‘show logging’ and controller diagnostics, then escalate to Cisco TAC if errors persist.
