Certainly not an expert by any means, would think that you would need to supply more detailed line stats before one of the more knowledgable forum members can give a definitive appraisal of your line performance, such as:
ES rate
SES rate
CRC error rate
US & DS SNRM trend
Basic observations from the limited stat's provided:
G.Inp (Re-Transmission) is active on US and DS
DS G.Inp is likely to be Re-Tx High Profile, can't say for sure but based on INP being > 50 as observed on lines I monitor.
(definitive check would be Bearer Zero INPRein being "1")
DS G.Inp being active is likely an indication that DS error rate is high and has been applied by DLM, usually removed again by default as soon as error rate decreases.
As your modem/router up time is so low, just over 4 hours, it's difficult to say what has happened or what's going to happen with DLM.
Has the line been dropping synch or are you re-synching/re-booting manually ?
What make/model is your modem/router ?
Who is your ISP ?
I assume you are on a 80/20 contract as your DS line synch is > 40.
Are you in a position to utilise any of the available utilities such as DSLStats or RouterStats to harvest detailed line stat's ?
A lot of questions I know but will hopefully help to attract the interest of one of the many knowledgable patrons on the forum who I'am sure will come along soon.
