asterisk users - Oct 2003 - Channelbanks for use in europe (Sweden)

Hi!

Is there anyone that are using a E1-channelbank and have any tips about some
type? Im looking at the TE410P and use one port for a PRI (Euro-ISDN, I
think we're using some slightly modified version here in Sweden, but
I'll
check that tomorrow) and connect one port to a channelbank for 30 analogue
telephones.

It would also be great to get callerid on the analogue phones, so it would
be intresting to know how
the channelbank sends the callerid (DTMF or FSK) if it sends any callerid?

Best regards, Lars Fredriksson

AFAIK, it is not the channel bank that encodes the caller id at all.
The channel bank only has to support sending on hook audio. The caller id 
is sent by asterisk as inband audio, and the channelbank just passes it on. 
I believe it is just a modification of a regular low speed modem format - 
fsk based, not dtmf at all.

Just remember part of the design of the TE410P is that you can use T1 
channel banks (you only get 24 ports) , if you buy these in America they 
are significantly cheaper than E1 channel banks. Just assign one of the 
incoming ports on the TE410P to be T1 not E1.

unfortunately you loose 6 channels/span and not all t1 channel banks
are certified for using in EU
