ISDN Networks
Total Recall VR uses a purpose built, high-impedance, ISDN PRI link (E1 or T1)
tapping card to capture signalling and audio on ISDN PRI links. This interface does not
interact with the calls and audio on the links in any way.
Total Recall VR may be equipped with one or two tap cards. You can connect only one
ISDN PRI link to each tap card. As a result, the number of tap cards determines the
number of ISDN PRI links that you can connect to Total Recall VR.
DO NOT connect ISDN BRI (2B +D) links to Total Recall VR. Total
Recall VR can only record calls on ISDN PRI (E1/T1) links.
