However, thanks to J52 - a mode that only AETA Audio includes as standard on all of its products - the station codec set for Layer III will recognize the incoming algorithm and automatically default backto Layer II operation in order to communicate. The beauty of J52 is that it requires absolutely no operator intervention. No longer do you have to manually change the algorithm, and never again will you miss an incoming signal because of an incompatibility.Operational Information� Dialing- Built-in keypad- Automatic answering� User Interface- Backlit LCD display: 2 x 16 characters- Dust/breakage-free Lexan� keypad� LEDs- Audio input level , 18 LEDs for: 0 to -27 db(referenced to the clipping level = 16 dBu)- Int voltage alarm: 12v & 5v- Ext test alarm- Ext clock alarm� Network interface- ISDN: U, S/T single basic rate interface (RJ45)- V24 (sub D-9)� General- Loopback mode for network testing- Universal power supply: 85 to 260 VAC- Dimensions: 3.75 x 19 x 12.5 in.
