Key System Architecture, Maximum Size
1.6.3
Together with the highly flexible Siemens codec filter circuits SLICOFI, SICOFI,
SICOFI-2 or SICOFI-4 the ELIC constitutes an optimized analog subscriber board
architecture.
The EPIC-1 part of the ELIC handles the signalling and voice data for up to 64 subscriber
channels with 64 kbit/s. The SACCO establishes the link to the group controller board.
