Hardware Functional Specification
This card is a control card for the expansion shelf.
It controls the option card contained in the expansion shelf according to the instructions of NS1000 main CPU.
On the STACK-S card are LEDs in two colors that indicate the status of the card and the bus cable connector for connecting to the
STACK-M card.

ASIC Block
This block is capable of controlling the EC bus, which is a way of accessing the option card.
It also realizes TSW function by accessing the CT bus (128 timeslots).
At the same time, it is capable of controlling conference call with a range of 3 parties of 10 to 8 parties of 4.

CPU Block
The CPU block consists of IC200 (CPU), X201 (Clock for Timer), IC202 (spread clock).
IC200 is the CPU that controls the expansion shelf, X201 is the clock that the CPU uses internally, and IC202 is a driver to trans-
mit the CPU operating clock from the ASIC block.

Memoy Block
This block consists of IC301, 302 (SDRAM), IC303 (flash ROM), IC304 (SRAM), separate the main and local buses: as well as
IC305, IC306, IC307, IC308, IC309, IC310, IC311, IC313 which separate (Logic IC).
In flash memory are stored the boot and operating programs.
SDRAM is the region in which the operating program is actually expanded and run SRAM is the region in which an error log is
temporarily stored during operation.
Access to ICs and all RAM aside from SDRAM is done through the separated local bus.

FPGA Block
This block consists of IC501(FPGA), IC502(Serial Flash ROM).
It is capable of exchangeing voice data between the CT Bus (1024ch) within the unit and the voice bus (384ch) from STACK-M.
Furthermore, it receives the highway clock and Frame Head from STACK-M, and outputs them to CT-BUS.
It also generates single or DTMF tones in any highway or time slot.

Commnunication Controller block
This block consists of IC600(CirkLink) and X601 (source clock 40MHz).
The CircLink is a communication controller to realize control message communication between STACK-M and STACK-S.
The CircLink chips on STACK-S card and STACK-M card are connected one-on-one basis.
Through message communication among controllers within the STACK-M card mounted in the NS1000, packet communication
with NS1000 main CPU is made possible.
LVDS(IC601) is used for actual communication.

Stacking cable Connection Block
This block consists of IC601, 602, 603, 604, 605 (LVDS) and CN601 (Stacking Cable Connector).
Each control signal is converted to a differential signal through LVDS device and sent to the stacking cable.
The twisted pair cable with 50 pairs is used to connect between STACK-M card and STACK-S card.
