 * On DSLReports forums (PCB images)
 * The Linksys SPA2102 is gateway router/analog telephony adapter (commonly referred to
 * as ATA) with two FXS ports, which allows for the connection of two “normal” telephones to
 * a VoIP provider using the Session Initiation Protocol (SIP) protocol. The product is based
 * on the SPA-2100, made by Sipura Technology, which was acquired by Cisco in 2005.


 * The ethernet chip is likely a custom version made for Sipura. The board picture
 * (see bellow) shows a Micrel SPN801024 with lot number GFK7344.1M01.


 * Another picture (found here) shows a Micrel SPNZ801030 whit lot number GFS7976.1.
 * Both lot numbers are close to GFK7343.1MEG and GFS7975.1MED found in the Micrel
 * MTBF report (see links & screenshot), which identify a KS8842 chip.
