Just a quick question, I will be building some servers in a lab utilizing Digium E1 cards. I would like if possible to avoid the expense of installing an e1/ISDN30 in my lab. I have two questions really, first does anybody know of an effective simulation tool I can use to replicate a real world PRI but without the telco line being installed. And secondly, can I have a scenario with 2 asterisk servers with digium e1 cards 'back to back' one configured as the network side and the other configured as the client side (can I just use a single cat5 straight through cable between them ?? and cant the Digium e1 cards operate ok in both modes?)
You can put two Asterisk-boxes back-to-back. Configure one as pri_cpe and one as pri_net. You need an E1 cross over cable which is different from an ethernet cross over cable. Search the net for which pins to connect.
Other alternatives exist. They may be closer to what you would see from a real pstn connection, but they are also a lot more expensive.
