GENERAL DESCRIPTION
The CopperWing12 ADSL Chipset family targets a complete set of solution for Central Office (CO) ADSL technology integrating also processing and management capability to provide the best solution for ATM/IP DSLAM, ATM/IP mini DSLAM and "Pizza" boxes. The chipset integrates all ADSL/ ADSL2+ functions from ATM/IP interfaces to the line in three devices:

■ Two data pump chip options:
   – STLC61255: 12 channels ATM ADSL Data Pump
   – STLC61256: 12 Channels ATM/IP ADSL data Pump with embedded Cell Processor
■ STLC60454: 4 Ch ADSL/ADSL2+ AFE with integrated receiver and LP filters
■ STLC60243: Dual channel Line Driver

ADSL SUPPORTED STANDARDS
■ T1.413 Issue 2
■ ETSI RTS/TM 06006 - ADSL over ISDN
■ ITU G.992.1 - G.dmt, Annexes A, B, C, I
   – Amendment to G.992.1 Annex C
