Product Summary
The AD6438-2BS is an ATM Interface and Framer. It inserts ATM cells into an ADSL line, with functions that correspond to the Transmission Convergence (TC) sublayer in the BISDN protocol reference model (per ITU-T I.432 and T1.413 Issue 2). Also it interfaces an ADSL modem to an external system, at either CO (Central Office) or RT (Remote Terminal) modem, using a standard UTOPIA 1- or 2-port (byte-wide, Cell or Byte Mode).
