CM2000 Modem: blinking downstream light

Thank you for the response. Below is a copy of the "modem event log." Is this the info you requested? I have been often in touch with RCN and the modem has been "reprovisioned" several times. Also, I have had (and paid for) three service calls. This first time the tech replaced the connectors at the ends of the cable, and removed one splitter her found in the line. The subsequent visits found the signal to be within spec, and the tech stated that since I had my own modem that was all they could do since they did not support customer-owned modems.
