Together with the highly flexible Siemens codec filter circuits SLICOFI, SICOFI,
SICOFI-2 or SICOFI-4 the EPIC constitutes an optimized analog subscriber board
architecture.
The EPIC-1 handles the signalling and voice data for up to 64 subscriber channels with
64 kbit/s. The HSCX establishes the link to the group controller board.
