Cisco 1600 Series Modular Routers

Cisco IOS Reliability Services: Hot Standby Router Protocol (HSRP); advanced routing protocols such as Open Shortest Path First (OSPF) and Enhanced Interior Gateway Routing Protocol (EIGRP) for load balancing, multipath routing, and minimizing network congestion

End-to-end QoS controls: Priority Queuing (PQ), Custom Queuing (CQ), Weighted Fair Queuing (WFQ), Generic Traffic Shaping (GTS), and Resource Reservation Protocol (RSVP)

Generic Routing Encapsulation (GRE) Tunneling

Virtual Private Dialup Network (VPDN) tunneling: Layer 2 Forwarding (L2F) Protocol

Standards-based encryption based on Data Encryption Standard (DES)

Cisco IOS technologies offer the most complete solutions for VPN security and mission-critical reliability/availability with features such as:

VPNs - A VPN connects private networks and remote users together by using a public network (such as the Internet) but provides services and capabilities that seem like those offered by dedicated private lines. Internet-based VPNs can significantly reduce WAN costs. In order for VPNs to provide the same benefits as dedicated lines, they must offer similar levels of security and mission-critical quality to guarantee availability.

Note: see Cisco IOS Firewall Feature Set data sheet for further details on optional firewall functionality.

The Cisco 1605-R router with Cisco IOS Firewall Feature Set, two Ethernet interfaces, and one WAN slot for all popular WAN connectivity, makes an ideal integrated and flexible firewall for small offices. This integrated router/firewall effectively segments an internal, secure local area network (LAN) from a perimeter LAN exposed to an untrusted network (such as the Internet), thus creating a "demilitarized zone."

CBAC provides stateful application-layer security by examining traffic sessions on a per-application basis, and allowing return traffic through the firewall. When a session is initiated internally, CBAC writes a temporary, session- specific ACL entry, and deletes the ACL entry upon session termination.

Improved logging and alerts

Attack detection and prevention

Java blocking

Context-based Access Control (CBAC)

Additionally, the optional Cisco IOS Firewall Feature Set, available on all Cisco 1600 models, provides formidable firewall functionality, including:

Router/route authentication

Lock and Key (dynamic ACLs)

Standard and Extended Access Control Lists (ACLs)

Perimeter Security - This refers to the security which controls traffic entry and exit between any network boundaries, such as between private networks, intranets, extranets, or the Internet. Cisco IOS perimeter security technologies provide a highly flexible, superior solution with standard features such as:

In order to leverage the unprecedented opportunities offered by communications and commerce over the Internet, private information, must remain secure. Cisco IOS security services provide many technologies to build a custom security solution. The elements of security services include perimeter security, encryption, and VPN tunneling.

The ISDN BRI Leased Line S/T card is designed specifically for the Cisco 1603 and 1604 routers. It is intended for users which require a dial-up ISDN BRI line (from the Cisco 1603 or 1604 router's fixed-WAN port) and an ISDN leased line (from the ISDN BRI Leased Line card inserted into the Cisco 1603 or 1604 router). This card is automatically configured only in ISDN leased line mode. ISDN leased line is also known as ISDN Digital Subscriber Loop (ISDL).
