ADX - new patented active E1 DDF (Digital Distribution Frame) Combining and compacting a SDH STM-1 ADM and E1

DACS into the dimension of Krone LSA-Plus and able to fitinto the existing Profil rod

Zero touch Digital Distribution Frame for 2Mbps circuit

ADX - General

8/20/2008 ADC Proprietary and Confidential 3

ADX - Passive versus Active

Passive DDF Huge amount of copper

cables between ADM andDDF

Huge effort for the cableinstallation

Limitation of the distancebetween ADM and Switch

Problem with electricalinterference

ADX - Passive versus Active

ADM SwitchActive DDF

Active DDF Reduced cable cost Reduced installation cost Reduced footprint Reduced power consumption Reduced cabling space between

ADM and DDF Increased distance between

ADM and DDF Reduce the problem with

electrical interference

ADX Product Design - E1 Tributary Card

The E1 Interface card is based onthe LSA-PLUS (IDC) connectiontechnologie. Use the LSA-PLUSinsertion tool to connect the wiresto the card.

E1 Interface Card has eight 120ohms interface complying to ITU-TG.783.

E1 interface : ADC101 2.048 Mb/s+/- 50 ppm, HDB3 coded signal.According ITU-T G.703-6
