Cisco 803 ISDN BRI router with 4-port 10BASE-T hub and 2 analogue telephone ports.

The Cisco CISCO803 is an 800 series ISDN router combining a 4-port 10BASE-T Ethernet hub with an ISDN BRI (S/T) WAN interface, built for telecommuters and small offices needing an all-in-one voice, fax and data connection.

The 803 runs at 33MHz with 8MB of default DRAM and supports ISDN BRI at 2 x 64kbps (or Switched 56 at 2 x 56kbps), plus bandwidth-on-demand, dial-on-demand routing and access control lists for WAN optimisation. Two RJ11 analogue telephone ports let a single ISDN line carry voice, fax and data together. Cisco recommended the 876 ADSL router as the standard replacement once the 803 reached end-of-sale.

It’s a good match for organisations maintaining an existing Cisco 800 series ISDN estate who need matching hardware for expansion, redundancy or like-for-like replacement.
