The following pages contain working sheets to facilitate the programming of the DOC
incl. EPIC-1. For several tasks (i.e. initialization, time-slot switching, …) the
corresponding registers are summarized in a way the programmer gets a quick overview
on the registers he has to use.
• Register Summary for EPIC Initialisation
• Switching of PCM Time-Slots to the CFI Interface (Data Downstream)
• Switching of CFI Time-Slots to the PCM Interface (Data Upstream)
• Preparing EPICs C/I Channels
• Recieving and Transmitting IOM-2 C/I Codes
• DOC Port and Signaling Multiplexers
• DOC Clocking Multiplexers
