Overview of Cisco 700 Series Routers
The Cisco 700 series routers connect Ethernet LANs to corporate networks over Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) lines. The Cisco 700 series routers offer multiprotocol routing capability between WAN and LAN ports, as well as the ability to function as a transparent bridge.
The Cisco 700 series router is available in five models. Table 1-1 lists the model numbers and the WAN and LAN interfaces available on each model.
Table 1-1 : Cisco 700 Series Router Models
| Model | Interfaces |
|---|---|
| Cisco 751 | 1 Ethernet and 1 ISDN BRI S/T |
| Cisco 752 | 1 Ethernet, 1 ISDN BRI U, and 1 ISDN BRI S/T |
| Cisco 753 | 1 Ethernet, 1 ISDN BRI U, 1 ISDN BRI S/T, and 1 analog telephone |
| Cisco 761 | 1 Ethernet and 1 ISDN BRI S/T |
| Cisco 762 | 1 Ethernet, 1 ISDN BRI U, and 1 ISDN BRI S/T |
| Cisco 765 | 1 Ethernet, 1 ISDN BRI S/T, and 2 analog telephone |
| Cisco 766 | 1 Ethernet, 1 ISDN BRI U, 1 ISDN BRI S/T, and 2 analog telephone |
This section contains information about the Cisco 700 series features, including the available ports.
The Cisco 700 series routers connect to remote devices across ISDN BRI lines by dynamically initiating and terminating ISDN connections based on several factors, including the level of the traffic on the Ethernet LAN, dynamic routing parameters, and static routing parameters. This feature is called dial-on-demand routing (DDR).
The 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 onto the ISDN line. After they arrive at their destination, the packets are decompressed and sent onto the remote LAN.
Table 1-2 lists the Cisco 700 series hardware features.
