ADSL runs over analog telephone lines on the CISCO857-K9, the Cisco 857 ADSL router. The ADSL chipset is the ST-Micro DynaMiTe (formerly Alcatel Micro Electronics, 20190) and the standards are T1.413 ANSI ADSL DMT issue 2, G.992.1 ITU G.DMT, G.992.3 ITU G.hs and DSL Forum TR-067. The chipset does not interoperate with carrierless amplitude modulation/phase modulation (CAP) ADSL lines.
The LAN side is a 4-port 10/100BASE-T switch. The router has an RJ-45 console port, 64 MB DRAM and 20 MB flash, with the memory the same at default and maximum. Firewall and IPSec VPN support are included, and the 857 has no 802.11b/g radio, unlike the 857W models.
Power comes from an external supply at 100 to 240 VAC and 50 to 60 Hz, with 26 W maximum output. The unit measures 2.00 x 10.25 x 8.50 in. and weighs 2.10 lb (0.954 kg). Other routers are in Cisco routers.
