We have recently acquired an ISP that had many ISDN customers using Pipeline 50's and 75's We are noticing that after a while (12-hours to a days) we start to notice significant packet losses across the ISDN link. Rebooting the Ascend immediately takes care of the problem but the cycle continues after a while again. Before the Pipelines were connecting to a MAX4048 without any problems Are there any special configs needed on the TC or Ascend to work together? We are running DSP 2.1.85 and HiperArc 5.1.99 I have disabled compression on digital calls and changed the ascends from MPP to MP Radius user file snippet coachxxx Password = "xxx" User-Service = Framed-User, Framed-Protocol = PPP, Framed-Routing = None, Framed-Netmask = 255.255.255.248, Framed-Address = 216.221.55.57, Framed-MTU = 1500 Any suggestions greatly appreciated.
