Polarity reversal on SLI board

[OXE_4400]

Is it possible polarity reversal on SLI board?
I mean that OXO is connected with PSTN using ISDN BRA and I need to get polarity reversal on SLI port after remote end answer or end of call.
Or maybe OXE is able to do something similar.

Hey OXE
shouldn't it be sent by the PSTN? I mean what OXE does is detect the change from the PSTN on the analog interface and end the call. But if using ISDN, isn't it digital interface?

I need to connect call-box behind PBX with call duration detection based on polarity reversal.
OXO or OXE gets conversation start/end through ISDN signalling, there everything OK.
But how to send start/end from PBX using polarity reversal to call-box connected on analog user board SLI ?

Never hear about this in OXE. In R10 overview exist something like this (but not the same) - "The eZ32-2 board supports the CPC feature (Calling Party Control) also called “Open Loop Disconnect”". But nothing about polarity reversal.

OXO support polarity reversal detection on analog trunk line APA, but regarding SLI ...?

Hi

I have never heared about polarity reversal in analog extension board. I think you can't do it with OXE/OXO. But for analog trunk cards OK, it works fine.
