Hi Tony- Two E1's running on a TE405P should be a better choice, as the TE405 is capable of "bus mastering" which gives better performance. Besides, you only use one PCI slot in this configuration. However, of course you lose board redundancy.
You can run 1 E1 port to another by using a crossover cable, as follows: 1 -- 4 2 -- 5 4 -- 1 5 -- 2 You can then use the outbound call generation capability of asterisk (see the file called sample.call) to generate calls on 1 span, and receive them on the other with the normal dialplan. I've done this many times for load testing. You can do it on one machine no problem. There's a little more information about this on the Wiki: http://www.voip-info.org/wiki-Asterisk+dimensioning Regards, Scott Scott M. Stingel President, Emerging Voice Technology, Inc.

Hi, I have a project coming up which will need to interface Asterisk to E1 trunks in the UK. I have a couple of questions which I hope someone can answer, or give me some pointers: 1. If I want two E1 trunks, is there anything to choose, performance-wise, between using two ports on a single TE405P, and using two E100P cards? 2. How can I test the E1 operation in the lab, which doesn't have an E1 line available, before taking the unit to the installation site? Can I run two Asterisks back-to-back? Can I run one port into another on a single TE405P? I couldn't find anything on the above in the Wiki; if I didn't look hard enough, please tell me where I missed. Thanks. Any advice would be gratefully received!
