The CISCO876-K9 is the Cisco 876 ADSL over ISDN router, and it is one of two models in the Cisco 870 Series with an ISDN Basic Rate Interface (BRI) S/T port. The port serves out-of-band management and dial backup, and the 876 has integrated ISDN dial backup. An optional software upgrade on the 876 adds integrated dial backup for ADSL using the ISDN S/T port.
The WAN side is ADSL over ISDN, with ADSL2 and ADSL2+ hardware ready. The LAN is a managed 4-port 10/100BASE-T switch with autosensing MDI/MDX. Default memory is 128 MB DRAM (256 MB maximum) and 24 MB flash (52 MB maximum), and the console port is RJ-45.
An external 100 to 240 VAC supply powers the router at 50 to 60 Hz with 26 W maximum output, and an optional external PoE adapter can feed IP phones. The non-wireless form measures 2.00 x 10.25 x 8.50 in. and weighs 2.10 lb (0.954 kg) at most. Other models are in Cisco routers.
