We have a PRI T1 line connected to our MultiAccess so users can dial into it for remote access and I am wondering if it can also terminate to a 64k BRI circuit?

The MA30120 can terminate only T1-RBS, T1-PRI and E1-PRI digital communication lines. These are the only types of communication lines that can be physically connected to the back of the MA30120. Please Note: If the BRI circuit is terminated at the remote user's location, they can originate 64k HDLC/PPP or 128K MLPPP ISDN calls into the MA30120. The MA30120 will also accept 19.2kbp or slower V110 ISDN calls.
