Just curious what is the topology of RCN Lehigh Valley's HFC Network and what brand line gear (Nodes, taps, passives) are in use?
I see a lot of neglect to RCN LV (Analog Crush, last market to get lots of HD, most likely last market to get DOCSIS3, etc..), so I wonder if it's a limitation in the line gear that was installed.
Anyone know the answers to these questions?
What's the bandwidth? 750, 860, or 1002 MHz ?
What brand gear? Motorola, SA, Phillips/Magnavox, CCOR, etc?
Generally how many amps past the node? Node+1 fiber deep, Node+2, Node+3, etc...
Are all RCN area's two way 750+ MHz? If there are non 2-way area's, does this mean it's old school tree and branch 50+ amplifier cascades? What would the forward bandwidth be in non 2-way area's if there are any left?
Is RCN running HRC, or IRC offsets, or is it all standard bandplan?
Are the nodes 4-way segmentable? How many homes passed per node, and how many subs on each upstream port?
In the headend, are any special multipass VBR encoding schemes used? For instance Imagine Media has a 15:1 SD compression rate available, as well as a 3:1 HD compression rate available.
Who's the VOD provider? Concurrent, Seachange, Tandburg, etc? How many QAMs per node are dedicated for VOD services?
Are DOCSIS 2.0 upstreams in use at all? 64QAM or 5.12msps 16QAM?
Any pathtrack, cheetah, or other performance monitoring gear? Are status monitors used in power supplies, nodes and amplifiers?
Is there an issue with the system amplifier cascade or agc pilot frequency that makes doing analog crush difficult?![]()
