I have inherited a Norstar MICS 6.0 ksu. I have to connect 2 ISDN lines to this system and don't know what to ask telco to determine if I need PRI or BRI cards. Can the existing T7324 phones work with the ISDN lines.
Thanks in advance

You need to order a BRI card, I believe. And yes, your M7324 phones are compatible.

weco,

a BRI (Basic rate Interface) is comprised of two channels (lines) and a PRI is comprised of 23 channels. That should help you determine which one you need.

2 BRIs will give you 4 "lines"
