Does anyone out there have any experience with using a PRI with a HiPerDSP (2.0.51) and an Alcatel 600e switch (version unknown)? The CLEC with whom one of our clients connects with is having to "bounce the D channel" a couple of times a day in order to keep the DSP accepting traffic. When the problem occurs, the user gets a busy; TCM shows nothing out of the ordinary on the DSP. FWIW, the switch type we are using in the DSP config is priSw5ESS since that's what we were told the Alcatel is configured to emulate. Any pointers/hints welcome...
