Got a chassis with 10 PRI's into it. Just looking for any opinions or information on the following issues:
#1. Telco says the switch is a 5ESS. If we configure the DSP's for 5ESS we intermittently lose the D-channels. Telco says that even though it's a 5ESS switch, the PRI's are configured "standard" or "national" and that we should set the Total Control for NI2. Is this normal/correct? Set it up for NI2 and D-channels appear stable and it answers calls.
#2. Telco says that even though each PRI has it's own D-channel, that each PRI is configured as it's own single-PRI NFAS group with Interface ID 0. It seems to answer calls whether I just configure for FAS or if I config for NFAS assigning a different NFAS Group to each DSP. Does this matter at all? Seemed kinda wierd, but I haven't worked with PRI's that much.
#3. All 10 PRI's are in a single "hunt group" with 4 different numbers assigned to that group. Regardless of the phone number I call, the call comes into the first DSP. If I busy-out that first DSP, dialing any number results in a busy-signal. In other words, if one DSP is not there, calls don't roll over to the next available PRI. I'm pretty sure this is a telco config issue - but is there something I may be doing wrong? Just want to make sure.
I have noticed that if the switch type is not set correctly, calls will get answered properly, but the "soft busy" command will give the results you are seeing. Specifically the switch was 5ess but the settings on the TC box were set to NI2. Exactly what you are seeing.
