several key patents for C-DOCSIS.

5. Remote MAC-PHY vs Remote PHY
REMOTE MAC-PHY
• Remote MAC-PHY allows you to put one or more smaller CMTS in the field. Putting a CMTS at the
node is more economical, especially when addressing smaller, remote service areas. Allows you to
allocate the US + DS MAC & PHY to the remote node.
• Remote MAC-PHY reduces the amount of fiber and avoid a lot of cost and complexity. This also
improves reliability, since there is less RF plant to maintain.
REMOTE PHY
• With Remote PHY, you still need to have a centralized CMTS in the headend, because only the PHY
layer is distributed. This is generally going to be a larger piece of hardware capable of serving many
subscribers, which is less flexible as far as scaling options.
• With Remote PHY providers allocate the US + DS PHY to the remote node, RF processing will be
distributed from head end to remote node
• With Remote PHY, every node needs at least one point-to-point fiber back to the headend.

6. Worldwide Evolution
• Industry-leading MSO’s are evolving towards DCA solutions
– Comcast has announced to add DCA into roadmap, released their RFI
– Other operators following this direction
• Remote MAC-PHY is the most mature solution at present
– Most shipment, most deployments
– Mass devices already operating in the actual fields
• Remote-PHY is a solution supported by traditional vendors
– Traditional vendors such as Cisco and Arris move to R-PHY as a solution
offering increasing provider hardware needs

72. What others are saying…
I was unexpectedly surprised. The pre-planning that Scott and Buddy did obviously paid
off. I can’t tell you what they might have done different to have made it any smoother,
which is a testimony to how well it went. We’re very happy with the level of service we
and our customers now receive from ZCorum. We are also big fans of their TruVizion
diagnostics software, which is much better than what we had before.
WEHCO Video
I’m looking forward to working with ZCorum, and am already happy with the level of
customer service they’ve been providing to our customers and my staff. I also know
that my techs are excited about the TruVizion diagnostics tool.
Polaris Cable
I can’t imagine not having Truvizion anymore. Our employees from a CSR to a line tech
to the headend tech all use Truvizion for monitoring and troubleshooting. It has saved
us lots of man hours in finding problems. And support services for end users have really
reduced the truck rolls and calls we get at our offices.
