The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and tel evision reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Cisco 700 Series Router Installation Guide

Overview

Cisco 700 series routers connect Ethernet LANs to other networks over Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) lines.

Cisco 700 series routers offer multiprotocol routing capability between WAN and LAN ports and can function as transparent bridges.

Product Features

This section describes the major features of Cisco 700 series routers.

CiscoSecure Authentication Agent Support

The CiscoSecure Authentication Agent (available for Windows 95 and Windows NT 4.0) application simplifies the use of token authentication over ISDN. There are two authentication modes: single authentication and double authentication.

CHAPTER

The Cisco 700 series router operates in single authentication mode when Token Authentication Support (TAS) is enabled. The CiscoSecure Authentication Agent is available on the Cisco Website.

Fast Step Support

Cisco 700 series router software Release 4.0(1) and higher supports the Cisco 700 Fast Step software. Cisco 700 Fast Step software simplifies the setup, configuration, and monitoring of Cisco 700 series routers.

Overview 1-1

Product Features

Cisco 700 Fast Step runs on Microsoft Windows 95, Windows 98, and Windows NT systems. It is provided with your router on the Cisco Fast Step CD-ROM. The application is also available on Cisco Connection Online (CCO).

Always On / Dynamic ISDN (AO/DI)

The Always On/Dynamic ISDN (AO/DI) networking service provides an always-available connection to packet-based services through the WAN. For the user, AO/DI reduces costs by using the D channel to make low-speed data transfers. For service providers, AO/DI removes a significant amount of data traffic from the voice network.

The D channel is an always-available, packet-oriented link between the remote office and the central office. The customer premises equipment (CPE) can use the D channel to pass Multilink Point-to-Point Protocol (PPP) and Transaction Control Protocol and Internet Protocol (TCP/IP) encapsulated in X.25. The D-channel X.25 packets are handled at the central office by the X.25 packet handler, so these packets can be routed without crossing the circuit-switched switch fabric.

When D-channel bandwidth exceeds a defined threshold, the router places one or more ISDN B-channel calls to increase bandwidth. When bandwidth requirements fall below a defined threshold, the B channels are released.

A maximum of four switched virtual circuits (SVCs) can be used for AO/DI. If a D-channel connection is not available, the router uses the first available B channel for a call. After the D channel PPP link is established, it is not torn down. If Bandwidth Allocation Control Protocol (BACP) is configured, Bandwidth on Demand (BOD) is negotiated by using BACP.

Performance of the multilink protocol declines when the bandwidth of the underlying links varies widely; therefore, the router idles the D channel when the B channels are in use. (RFC 1990 describes how packets can be redirected using the multilink procedure.) After the number of links drops to one and that link is idle, the router returns to normal operation.

DHCP Address Lease Time

With Cisco 700 series router software Release 4.2(2), you can specify the lease time for all the addresses. (The previous Cisco 700 series router DHCP server implementation assigned an IP address to the DHCP client with an infinite lease time.)

1-2

Cisco 700 Series Router Installation Guide

Enhanced AT Command Support

There are two modes of operation in the Controller PAD (TPAD) implementation that respond to the enhanced point-of-sale system (EPOS), Verbose and Terse. In Verbose mode, the response is in strings, such as “CONNECT,” “NO CARRIER,” “BUSY,” and so forth. In Terse mode the response is in numbers, such as 1 (CONNECT), 3 (DISCONNECT), 7 (BUSY), and so forth. In addition, in software Release 4.3.1, a series of TPAD commands have been implemented to support RIVA functionality.

Permanent Linkup Mode

In areas served by carriers providing flat-rate ISDN service, the lines can be permanently connected between the router and the central office switch. This feature can work on any switch type.

Triggered RIP

Triggered RIP enhances the Routing Information Protocol (RIP) and enables efficient dynamic routing over demand-circuit links such as ISDN. Defined in RFC 2091, Triggered RIP avoids the bandwidth overhead by sending updates for only those routes with changed metrics. Triggered RIP incorporates a reliable delivery mechanism to ensure consistent topology information.

Dial-On-Demand Routing

Dial-on-demand routing (DDR) allows the router to dynamically initiate calls as traffic demands to remote devices across ISDN BRI lines. The router also terminates ISDN connections based on the level of the traffic demanded on the ISDN line and the dynamic routing parameters.

Automatic Configuration From BOOTP

The automatic configuration feature allows the Cisco 700 series router to obtain a configuration file from a remote server using Bootstrap Protocol (BOOTP).

Overview 1-3

Product Features

SPID and Switch Automatic Detection

The automatic service profile identifier (SPID) and switch detection simplifies the use of ISDN terminal equipment and makes the equipment easier to use with fewer parameters to enter. With this feature, you only enter the local directory numbers with area code; no SPID number or switch type is required.

The automatic detection feature only applies to ISDN switches for the USA and Canada, usually an AT&T 5ESS Custom, DMS-100, NI-1, or NI-2 switch. The automatic detection mechanism might not work with any other switch, such as a Siemens switch. The automatic detection feature is only implemented in the U. S. image.

Bandwidth Allocation Control Protocol and Bandwidth Allocation Protocol

The Bandwidth Allocation Control Protocol (BACP) and the Bandwidth Allocation Protocol (BAP) define a set of rules to control dynamic bandwidth allocation to coordinate and negotiate the actual allocation and deallocation of the second channel.

NetBIOS Name Spoofing

If spoofing is set, the router keeps a local database of up to 100 Domain Name System (DNS) name entries and has an aging scheme to age out the unused name entries. When a WINS client sends out a NetBIOS Name query, the router can attempt to answer the query in place of the WINS server. If the router cannot answer, the router forwards the query packets to the server, which provides the response to the client.

DHCP Server and Relay Agent

DHCP automates IP addressing and reduces the number of IP addresses a site might require. Cisco 700 series routers can function as a dynamic host configuration protocol (DHCP) server.

Cisco 700 series routers can also function as a DHCP relay agent, but the router cannot act as a DHCP server and a relay agent at the same time. When configured, your router can relay DHCP requests and responses between DHCP clients and a specified DHCP server.

1-4

Cisco 700 Series Router Installation Guide

Port Address Translation

Cisco 700 series routers support port address translation (PAT) allowing a designated private IP network to communicate with the outside world. When configured, Cisco 700 series routers translate source addresses from an IP private network to a single, global, unique IP address before forwarding the packets to the outside world.

IP Address Assignment Through IPCP

The router can be assigned an IP address from the remote device using Internet Protocol Control Protocol (IPCP) address negotiation. The implementation is based on RFC 1332, and it supports IPCP options 1 and 3. (It does not support option 2, TCP/IP Header Compression.) IP unnumbered is also supported. IPCP address negotiation is on by default in any profile configured for IP routing. This feature does not support address assignment to remote devices.

Data Compression

Cisco 700 series routers support data compression using the compression algorithm QIC-122 standard, Stacker LZS. Data compression is a software configuration option that optimizes the ISDN line bandwidth. Packets are compressed before being sent to the ISDN line. After they arrive at their destination, the packets are decompressed and sent to the remote LAN.

Fee Pulse Mode

Fee Pulse Mode manages the ISDN connection based on the paid periods of time. If other thresholds indicate a call should be dropped due to low traffic, Fee Pulse Mode maintains the connection until the current paid period has expired. Therefore, you are not paying full price for part of a connection period. This feature is available only for NET3 (same as ETSI) switch types, and you must subscribe to Advice of Charge-During Active Call (AOC-D) supplementary service.

If the feature is enabled and idle time expires, the router checks the remaining time in the current paid period. The router maintains the connection until the end of the paid period, minus the disconnect time required to terminate the PPP and ISDN links.

Overview 1-5

Product Features

If the idle time expires too close to the end of the paid period to close the connections before the end of the paid period, the router extends the connection to the end of the next paid period, minus disconnect time.

X.25 Policy Routing

X.25 Policy Routing routes a specific IP packet to the target IP host through an X.25 D channel and provide the parameters needed for a X.25 D channel connection. The router does not require knowledge of POS transaction formats or protocols.

X.25 Over B Channel

Cisco 700 series router software Release 4.1(1) and higher includes a special image that supports the Cardway TPAD services (British Telecom). The connection is made through the Cisco 700 series router serial port.

X.25 Priority Queueing

Priority queueing improves the responsiveness of the D channel link. X.25 is a flowcontrolled, nonbroadcast multiaccess (NBMA) protocol. A high-priority packet might not be transmitted first, even when it is eligible. With priority queueing, data can be put into one of the four priority queues: high, medium, normal, and low. Packets with the same priority are sent on a first-in-first-out basis.

Leased Line Authentication Requirement Removed

In software Release 4.0(1) and higher, the authentication sequence is no longer required for leased line connections. (For 64-kbps or 128-kbps leased line connections, previous versions of the software required PAP/CHAP authentication to identify the corresponding profile.)

To eliminate the need for authentication, a user-defined profile named leasedline must be present and defined. If this profile is not present upon call connect, the router requires authentication to select the correct profile. If the call cannot be authenticated, the router

1-6

Cisco 700 Series Router Installation Guide

defaults to the Standard profile. Within the user-defined profile called leasedline, verify that PPP authentication is set to none. The switch types that support this feature are PERM64 and PERM128.

Security Features

Cisco 700 series routers provide the following security features:

• PPP authentication support, including Password Authentication Protocol (PAP) and

Challenge Handshake Authentication Protocol (CHAP)

• Password security for local and remote configuration access

• IP filtering based on source and destination addresses, source and destination ports, and
