Hi George, You might want to look at your FDL stats for each trunk.(see below) They will show how many Error Events (EE) you have had in the last 24 hours and in various increments up to 24 hours. The FDL events are 'seen' by the MAX and occur on the trunk itself. You can then take this information and go to your telco with it. Also rule out your hardware, if possible, by swapping ports and different RAS boxes to see if the CRC's follow the trunk or a particular port/chassis. All of this is assuming that you have the correct config for your trunks and have ruled that out as well. A Facilities Data Link (FDL) is a 4-Kbps digital link between a sender and the telephone company's monitors. The FDL uses Extended Superframe (ESF) framing, a framing format that consists of 24 consecutive frames, separated by framing bits. The telephone company uses an FDL to check on the quality and performance of T1 lines. It provides information at regular intervals to your carrier's maintenance devices. The MAX unit continues to accumulate ESF performance statistics in the FDL Stats windows, even if you do not choose an FDL protocol. Your carrier can tell you which FDL protocol to specify. The FDL Stats windows are the fourth and fifth options listed in the VT100 interface's status window Net/T1 window: 10-000 Net/T1 10-300 Line Errors ^ 10-400 FDL1 Stats >10-500 FDL2 Stats 10-600 Net Options The following display shows the contents of the FDL2 Stats window: 10-500 FDL2 Stats >Error Events...
