Specifications

Product Description:

The Cisco Systems Cisco1604-R Modular Router is a robust, enterprise-class networking device designed for businesses and branch offices that require reliable WAN connectivity with ISDN BRI and built-in NT1 support. Combining a 10Base-T Ethernet port with an ISDN BRI U-interface (with integrated NT1), this router enables direct connections to ISDN lines without requiring an external NT1 device, reducing setup complexity and space requirements.
Built on the trusted Cisco 1600 Series platform, the Cisco 1604-R runs Cisco IOS software and supports modular WAN upgrades, remote management, and industry-standard routing protocols. Its compact and rack-mountable design makes it ideal for small office networks, telecom applications, or legacy infrastructure requiring ISDN dial-up or backup routing capabilities.
This router is a preferred choice for environments that still rely on ISDN U-interface connections, such as certain government agencies, remote sites, labs, and specialized industrial networks.

Features:

Integrated NT1 – Native ISDN U-interface connection without external terminal adapter.
Dual WAN Interfaces – 1 x Ethernet and 1 x ISDN BRI U-interface (2B+D channels).
Modular Architecture – Expandable with optional WAN Interface Cards (WICs).
Cisco IOS Operating System – Stable, secure, and widely supported.
ISDN Features – Dial-on-demand routing, backup connectivity, and call setup.
Secure VPN-Ready – Supports ACLs and VPN tunneling for remote access.
Remote Configuration – CLI, Telnet, and SNMP for easy network administration.
Compact Design – Desktop or rack-mounted deployment.
