Using puppet for an Arris C4c CMTS

[Puppet_phile]

Hey guys, I'm new to this mailing list so go easy! 

I'm looking at setting up a complete headend via puppet, at the moment my attentions focussed on an Arris C4c CMTS; for people who aren't familiar - this is a network device used for terminating cable modems. Does anyone have any advice on where to start? It has an IOS like cisco (different command set), as far as I'm aware, no web gui, but telnet and ssh configurable once it has an IP, also TFTP send/receive - out the box though, just console connectivity I believe. Should I begin by looking at a proxy as seems to be the norm with F5 or is there a better way? Perhaps looking at copying configs via TFTP and linking in DHCP, any thoughts?

Thanks
