asterisk users - Apr 2010 - Split E1 ISDN service for another device.

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.

hi:
maybe you can use part of channels in 30B, for examle, 10 channels, and set the
rest to unused.

It sounds like the Polycom device is expecting to be plugged into four
BRI (2B+D) lines, and then it will place calls over those and bond the B
channels together. It may very well be possible to provide what you need
by putting a 4-port BRI card into your server (with the ports configured
in NT mode and running bri_net signaling)), connecting all four ports to
the Polycom device. Then when it places calls, the calls will be
processed through your dialplan, and you can forward them on to the E1.
There's no need to 'allocate' bandwidth to this device, it will ask
for
what it needs when it needs it.
