Bit Loading on New INID

Bit Loading on New INID

They just installed a new buried drop with twisted pair and a new INID. The INID is being used with a single pair instead of bonding. Can someone tell what this bit loading screen shot means? The first spike at about 200 mhz?

Re: Bit Loading on New INID

Your bitloading is normal for an iNID installation with a single line.

 

iNID installations preferentially use a very low frequency range (40 - 138 kHz) for the upload spectrum.  This is done to increase service distance.  Normally, both lines of the pair-bonded installation use this range and combined together, they get around 1.5 Mbps of upload bandwidth.

 

Your installation can't get enough upload bits in that low range with only 1 line, so some additional upload bandwidth is allocated in the 4+ MHz range.
