You need an E1 back-to-back cable.

Hi, I would like to realize a voip testbed that should simulate the scenario in which two companies have an asterisk PBX connected through a PRI-ISDN to the Telco operator. I have no experience of T1/E1 connection but I think that the above could be relized with 3 asterisk boxes equipped with Digium TE405P cards. One of the box will represent the Telco, the other two, the two companies PBX. I would like to know if it is needed something between the point-point connections or it is possible to just cross-connect them. I need the testbed to be representative of the real-world difficulties in putting on an Asterisk BOX for connecting to a PRI-ISDN: is other hardware needed (e.g. echo cancellers or failover switches)?
