We have CC Triple Pl;ay, and for optimal service, I had rewired our house with new RG6 "quad" coax, with 3 "home-run" cable runs from demarc box via a three-way splitter to two CC set-top boxes and the eMTA modem. Today I split the incoming Internet line to accommodate a new Netgear CM600 modem for Internet-only support, and down-graded existing Arris tm722g to voice-only. Signal level before split was excellent: (+)1.5-(+)2.5 dBmV downstream, and 36-37 dBmV upstream. After splitting, the expected insertion loss noted, with downstream at (-)1.5-(-)2.5 dBmV,, and upstream at (-)41-42 dBmV. My question is: as an alternative, can I split the incoming set-top box service between the eMTA and set-top, restoring higher signal to the Netgear Internet modem? Would one expect somewhat degraded performance of VOIP and dig. TV with this configuration?
