IIRC the DOCSIS standard requires the cable modem to have a connection to the head end before it gets a MAXCPE value. CPE is the number of public ip address' the cablemodem is allowed to giveout. Most modems reset the MAXCPE value when you reboot them. Others( like this cisco ubr924 ) allow you to set values in the hardware, but "can be" (mostly are in residential service) overwritten when they download their config from the headend.
Here is a basic troubleshooting chart describeing it. http://www.cisco.com/warp/public/109/cpe_no_connect_sm_1.gif Cisco is the best source of info on DOCSIS(Data?over?Cable Service Interface Specifications) that I can find.
