Block Diagram
The NS500 series PBX is constructed in Main Unit (NS500) and up to three expansion unit (NS520).
In Main Unit (NS500), CPU Board (MPR) (Master Processor) which controlls whole call of this system is equipped, and, in an
expansion unit, CPU Board (SPR) (Slave Processor) controlling various line interfaces in the unit is equipped with.
Each expansion units are connected to Main Unit with star topology, and time slot exchange function is equipped in Main Unit.
The exclusive interface between basic and expansion units are built with one pair of TDM interface of 8.192MHz, and voice chan-
nel, control channel and addition information channel are secured.
All interface cards except digital extension intefarce (DHLC/DLC) are controlled by CPU Board (MPR)/CPU Board (SPR) directly.

ence function.
NS300 can implement only DSP-S.
EXP-M
EXP-M is the expansion interface card which connects up to three expansion units to a Main Unit.
In each unit interval, below signals are connected:
1) 8.192MHz clock to supply from a Main Unit to an expansion unit by reference clock
2) Frame header signal of 8KHz
3) TDM bus of 8.192MHz from/to basic and expansion unit.
The TDM bus takes advantage of 128 time slots for a voice, control, addition information channel.
Exchange of the non-blocking is possible by a time switch in the Main Unit.
