Cisco C881G+7-K9 - Tabletop router, Black

The Cisco C881G+7-K9 Integrated Services Router (ISR) connects business networks using 3G cellular infrastructure. It supports HSDPA, HSPA+, and UMTS standards across four frequency bands. Designed as a wired-only gateway, this model does not include Wi-Fi, 4G, or 5G support. An integrated SIM card slot allows a direct connection to mobile data plans for primary or backup internet access. The device also features an Ethernet WAN port for traditional broadband connectivity. You can configure and monitor the router via a web-based management interface.

Local network traffic is managed through four Fast Ethernet LAN ports, providing 10/100 Mbit/s connections for office equipment. An external antenna is used to capture mobile signals in commercial environments. Traffic is secured using 128-bit AES, 256-bit AES, and 3DES encryption. The unit is powered by a 60 W AC supply. Built-in NAT and DHCP functions simplify IP management for connected local devices, and Quality of Service (QoS) prioritizes critical data streams to maintain stability during periods of network congestion.

• EIGRP and HSRP routing protocols – support dynamic routing and high-availability gateway redundancy.
• SNMPv3 and IGMPv3 management – provide secure remote administration and efficient multicast traffic control.
• IPv4 and IPv6 support – ensures compatibility with legacy and modern enterprise network architectures.
• MAC address filtering – restricts local network access to pre-approved hardware.
• Short Message Service (SMS) compatibility – allows the router to process text-based commands or alerts via the cellular network.
