Circuit Operations

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)
Green flash (60/sec): INS (line busy)
Red flash (60/sec): OUS
OFF: the power section failure
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 reserved for KX-TDA1186 option card.
