Can someone clarify about DHCP settings in cable modems, the IP addresses assigned to CM always shown within private IP address range (10.x.x.x), and they also need have public IP addresses to communicate with WAN network. When the modem DHCP settings are mentioned (in any context), does this refers to internal IP addresses or external IPs?
C * propagation constant in fiber is C*0.67 = 200,860,318.73536 m/s
C * propagation constant in coax is C*0.87 = 260,818,882.53696 m/s
One-Way Transit Delay Constant 0.80
Known:
Modem A has a timing offset of 3579
Modem A has a coaxial forward and fiber return, with a distance of 23174.6m in one direction
Forward is 256Q, Reverse is 64Q
So I have a situation needing to know if its possible and how to accomplish it.
We have a TX32 (slot 3) with TxPlus and 2 RX48 cards (slot 0 and 1). This particular CMTS is at a mobile home community and serves 3 properties. The way the fiber nodes are setup is one transmitter with builtin splitter then each node has its own return path receiver. The issue is we have 16 fiber nodes. I would like to bring each node back to a single upstream port on the BSR, but I am not sure how to bind the upstream ports on both cards to the same cable interface (0/0).
Hello,
I'm experimenting with Docsis 3.1 on a Cisco cbr8 (downstream only at this time). I have a downstream setup and am awaiting a couple of modems to arrive to test my setup. Does anyone know if there is anything specific that needs to be done in the config file for the modem to help out and take advantage of the new carriers?
