My current modem model no. is SBV 5120. Is the SB5101U a suitable substitute?
There is a list of suitable modems that will fit your particular needs on the Time Warner website. I do not think the SBV 5120 is on the list but the list is evolving so you should check. I do know this one is and it does work fine: Motorola SURFboard SB5101U DOCSIS 2.0 Cable Modem BYW the modem supports everything including VOIP.
