About the Cisco ISR 800/900/1100 C881G-4G-GA-K9 Cisco Integrated Services Router (ISR)
Cisco Integrated Services Router (ISR) models in the 800/900/1100 series deliver branch-office resilience through active-passive failover architecture with support for VRRP and DMVPN redundancy, enabling sub-second convergence for mission-critical WAN connections. The C881G-4G-GA-K9 combines a hardened routing platform with integrated 4G LTE and 3G HSPA+ cellular backup, ensuring continuous connectivity across geographically dispersed enterprise locations.
This Cisco ISR 880 Series device (part number C881G-4G-GA-K9) operates as a desktop or wall-mountable gateway, featuring 1 × 10/100 Fast Ethernet WAN port, 4 × 10/100 Fast Ethernet LAN ports with integrated managed switching, and a single Mini-SIM slot for global multi-band LTE coverage across 700/850/900/1700/1800/1900/2100 MHz frequencies plus regional variants. Built on Cisco IOS, it supports static routing, OSPFv2, EIGRP, BGP, and RIPv2 alongside IPsec VPN, GRE tunnels, and DMVPN for secure multi-site overlay networks. Security hardening includes Cisco IOS Firewall with CBAC/ZBF, NAT/PAT, ACLs, and IPsec encryption; QoS tools encompass DSCP marking, LLQ, traffic shaping, and IP SLA for application-aware forwarding. Management options include Cisco IOS CLI (console, SSH, Telnet), SNMP, and Cisco Configuration Professional. Operating temperature range spans 0°C to 40°C with external AC power input (100–240 V, 50/60 Hz) and full regulatory certification (FCC, CE, UL, RCM).
Typical Enterprise Deployment Scenarios
- Multi-branch WAN connectivity with automatic LTE failover for retail, banking, and healthcare networks
- Remote office gateway consolidating voice, data, and security services over hybrid wired/wireless links
- Field service and mobile workforce enablement via integrated cellular modem and Cisco routing protocols
- Branch-to-data-center IPsec VPN and DMVPN hub-and-spoke topologies with QoS traffic prioritization
- Industrial IoT edge gateways requiring firewall, NAT, and deterministic routing in temperature-controlled environments
Network engineers and IT procurement teams seeking reliable branch-edge routing with cellular redundancy should contact Omnixon Global for a detailed RFQ on the C881G-4G-GA-K9.
