I have two CMTS routers (BSR 64k), one supports 4 channel bonding and the second supports expanded bonding (up to 8 channels).
When I connect an SB6121 to the first, it registers on all four channels and the router shows it is properly bonded. Modem traffic graphs show traffic across all four channels.
When I connect the same modem to the second router which is configured for 5 channels, the modem shows it is registered on 4 channels but the router does not show it is properly bonded. Furthermore, traffic graphs show traffic on a single channel.
We have actually a configuration on 7225vxr with two card mc88u where we configure two DS port with one freq. and two other DS port with 4 freq. each. The two first DS port are for legacy modem and D2 and the other are for D3 modem.
Attached, you have the config filtered.
I have a doubt about Load-balance.
It's a good practice to mix all DS port on a Load-balancing group ?
For my point of view, this would be better to create LB group for legacy modem and other with D3 modem.
I just want to know if there is any article I can read about capacity planning in DOCSIS networks. I'm mostly interested to know if there are mathematical models or frameworks to project our access networks capacity (that will help us to know where a new equipment will be necessary). Any advice will be gladly received. I have found this paper:
I try to get a SBV6120E MTA "PacketCable 1.0 EMTA HW_REV: 1.0; VENDOR: Motorola Corporation; BOOTR: PSPU-Boot(BBU) 1.0.1.7-m3; SW_REV: SBV6XXX-1.0.3.1-SCM-01-CBNGA02-SHPC; MODEL: SBV6120E "
with NCS/MGCP online. It is just for a test setup in our lab with Asterisk and the MGCP-Patch.
