Description of Control System Circuits
4.2.1.1.
Reset
On startup, releasing the ASIC reset is executed by EC_nRST through MPR.
After releasing the ASIC, the local reset signal should be sent to CODEC by releasing the soft rest from MPR, and CODEC fac-
tor should be downloaded from MPR.
After releasing the ASIC, the local reset signal should be sent to CODEC by releasing the soft rest from MPR, and CODEC fac-
tor should be downloaded from MPR.
• LED operational state display LED (2 colors)
Red ON: Fault (includes RESET)
Green ON: INS (line free)
Green flash (60/sec): INS (line busy)
Red flash (60/sec): OUS
OFF: the power section failure
Green ON: INS (line free)

4.2.1.2.
Local Highway Interface
Packs 2.048, 4.096, 8.192 MHz highway (Max.64 timeslot). (voice communication bus in the circuit board)
The PCM data of arbitrary streams 0~15 (128 timeslot / 1 stream) on the CT bus can switch to the arbitrary local highway (64
timeslot) by the local TSW.
The timeslot configuration example of the local highway is shown below.
Timeslots between slot 8 and slot 15 are used by the Sub Board.

ASIC...IC3
• EC bus Interface
16bit/8MHz two-way address data multiplex self-bus (communication bus with MPR)
• CT bus Interface
Supports eight of 8.192MHz highway (128 timeslot) (voice communication bus with MPR)
• Local TSW
Timeslot switching between CT bus (1024ch) and local highway (64ch)
(Timeslot switching between the voice communication bus in MPR and that in the circuit board)
(Timeslot switching between the voice communication bus in MPR and that in the circuit board)
• Local Gain Control
Gain control of the local highway up-down 64ch by 1dB/step randomly
• GPIO Interface
A parallel interface that can be set in random interactively
