Digital Communications Agreement (DCP), proprietary agreement for Definity/CM systems

Auto Detection Auto Agreement - a networking agreement which automatically configure Avaya switches to abutment and accent cartage for IP phones. When ADAC is enabled and a IP buzz is affiliated to the switch, the about-face automatically configures the VLAN, port, and QoS settings. This agreement can be configured globally or on a port, and can be acclimated with IEEE 802.1AB/LLDP or by itself for auto advertent the phones, ambience VLAN PVID, Layer 2 and Layer 3 QoS values. An absolute cardinal of phones on a anchorage can be supported, simplifing IP Buzz configuration, and extenuative time, which improves Total Cost of Ownership of the VoIP solution.38
