We are looking at several small cable systems to possibly purchase and upgrade. The seller claims they are a 450MHz plant, but I'm not so sure. Can anyone tell me what the bandwidth limits are for an older model DC with the following part numbers: CA5408 XRFI another one is CA3602. I also spotted a Jerrold SSP-7, but didn't see a letter after it which used to indicate upper frequency, I believe.
Any help is appreciated.
