how many VIM E1/PRI modules can be used simultaneously on NV6355? Is it limited by DSPs? Can an additional DSP module be inserted?

We are testing nv 6355 and have E1 running just fine with a VIM E1/PRI module... just wondering how many E1s can we have running in the same box? Hoping to be at least two, and if there is a limit to that by the number of DSPs in the stock plane as it is with cisco, can a module with additional DSPs be added? Thanks in advance for any comment, cheers...

Wakawaka,

The NV 6355 DSP can support 27 Simultaneous G.729 AB or up to 30-G.711 active calls, so in a best case scenario we could support a up to 30-simultaneous SIP-to-TDM calls.  Understanding that we can't support full 2xT1/PRI or 2xE1/PRI's calls (due to DSP limitations), we've never tested the device with 2xE1/PRI or 2xT1/PRI VIM's ---- And given that it's not tested, it's not a supported application.
