The flexibility of the Intel Express Router 9201 makes it an ideal solution for the company with changing WAN connectivity requirements. For example, a company can start with dial-up support using the analog modem. Then, if a faster dial-up link is required, the router offers support for BRI (Basic Rate Interface) ISDN through the PC Card slot. The BRI ISDN connection could be used as the primary (or only) link to the WAN. It could also provide a safety backup, while using the WAN port as the main connection.

WAN links:

■One HDLC Serial Interface supporting Frame Relay, X.25, PPP, LAPB, Leased Line (TI/EI)

■One PC Card slot supporting either analog or BRI ISDN (EuroISDN only) communications using the following (modem not included):

For BRI ISDN (EuroISDN only):

– Eicon Diva* PCM

For analog modem communications:

–Xircom CreditCard Modem 28.8

–Xircom CreditCard Modem 33.6

–US Robotics Sportster PC Card 28.8 V.34 Faxmodem

–US Robotics Sportster 33.6Kbps PC Card 33.6 V.34+ Faxmodem

–US Robotics Courier V.Everything 33.6Kbps PC Card Modem

–US Robotics Worldport* PCMCIA V.34 CE Data/ Faxmodem 28.8Kbps

–US Robotics Worldport PCMCIA V.34+ CE Data/ Faxmodem 33.6Kbps

The BRI ISDN port can be a permanent or dial-up connection. The Intel Express Router support for Multilink PPP makes it possible to use the ISDN connection to gain extra bandwidth (bandwidth on demand) with a leased line connection running PPP at the same speed. In this case, the ISDN connection is made whenever WAN traffic exceeds a given amount, then closes when traffic levels return to normal.

WAN links:

■One HDLC Serial Interface supporting Frame Relay, X.25, PPP, LAPB, Leased Line (TI/EI)

■One integrated BRI ISDN port (EuroISDN only)

Intel Express Router 9400

Full Primary Rate Interface (PRI) ISDN performance for central sites or high-bandwidth environments (EuroISDN only).

AUI	CONSOLE	LAN	1 2SYSTEM

The Intel Express Router 9400 features a PRI ISDN (EuroISDN only) port that allows 62 connection profiles or links to be defined and up to 30 simultaneous connections. This high-performance capability makes the 9400 ideally suited as a central-site solution.

To reduce WAN costs, the Intel Express Router 9400 takes unique advantage of hardware-based data compression. This allows data compression at full line speed for the fastest possible throughput – a powerful feature not found in most other PRI ISDN routers in its category.

■One PRI ISDN port (EuroISDN only) supporting PPP and Multilink PPP
