[asterisk-users] Split E1 ISDN service for another device.

Thu Apr 8 01:35:47 CDT 2010

Hi All,

I know this is not specifically Asterisk related but I don't knew where
else to ask for help. Does anyone know how to or if it is even possible
to allocate 512kbit/s to an ISDN device from a 30B+D ISDN line.

The building the office is in has a E1 30 channel service (30B+D) but we
can not get any 2B+D ISDN services.  I have a HDX Polycom video
conferencing system that requires a 512kbit/s service.  I am told to
allocate 8B+D service from the 30B+D to the Polycom device.    Is this
even possible.

I have a Digium TE121 currently install in the server that the E1 ISDN
line is connected to.  The Polycom has 4 by RJ45 connections for the
512kbit/s service.

Any help would be appreciated. 

Regards

David.
