How it works
The Primary Rate Interface (PRI) is a service standard for larger companies within the Integrated Services Digital Network (ISDN)
set of specifications. ISDN PRI uses circuit-switched access technology to deliver high-quality voice, data and video services over
a high-bandwidth network. Maxis Switch and Network are connected with ISDN PRI via modem to customer's PABX.
