PRI or Primary Rate Interface is a ISDN equivalent of a T1 circuit. 

Most of our Merlin users currently use POTS lines. Plain Old Telephone Service or "POTS" Lines. Customers who switched from POTS lines to PRI usually experience a 25%-35% reduction in monthly telephone service costs

The standard analog line provides local dial tone for the small to medium size business. They are used for such things as making and receiving telephone calls, faxing, modems, security systems and credit card/ATM machines. For each Pots line there is a port in the Merlin system that is needed and you also pay a monthly line fee for each line. This can add up to be very expensive. POTS service is also referred as switched service. 

ISDN PRI digitally delivers your local, long distance, DID and internet service over one 4-wire interface. Your ISDN PRI T-1 has 23 channels that move voice and data along nicely at 64 Kbps. Consolidation makes sense because you reduce your network costs by incorporating PRI into your existing telecommunications blueprint, thus eliminating POTS line charges to the local exchange carrier. The D Channel is the 24th Channel. It constantly communicates with the Central Office ensuring the proper bytes and uninterrupted transmission. It also helps you comply with the E911 Law by delivering the phone number, extension number and physical location of the caller to 911. In addition, you automatically get Caller I.D., the name of the calling party on incoming and outgoing calls.
