yes, that means that you have a problem with your cable network.
-23 tenths of dBmV means that you power level is: 37. (-23 + 60)
the minimum number to get modem connected is 35 (-25)
you can change that by getting upstream signal better. contact your RF personel to fix that.
the -23 I assume is what the cmts is reporting from the modem into the receiver. it depends on a few things if that's good or not. example, if the receiver is configured to receive at a +5 or for some cmts's +50 and the modem is reporting 2.3 instead of 5.0 could be because that modem is at max transmit level. I would check to see what the modem transmit level is. assume it's at 61 or 58 depending on what the modulation and channel width is configured for. if you can, do a remote query or snmp to that modem and you will find the issue is too much loss on the return side, causing the modem to transmit at max level.
fix the return or root cause of too many splitters and it will go back to normal
