Mitel SX-200 DIGITAL Pabx General Description Manual

							General Description 
5. SOFTWARE OVERVIEW 
General 
5.01 The SX-200’ DIGITAL PABX software is divided into two sepa- 
rate sections, one to run the Main Control processor and one to 
run the Peripheral Control processors. Each software section has its 
own layers to carry out system functions. The layers defined below 
apply to both controllers unless otherwise specified. 
Physical Layer 
5.02 The physical layer consists of the operating hardware such as 
the microprocessor, its associated memory and input/output 
devices. 
Scheduling Layer 
5.03 This layer provides for scheduling of the different events to be 
handled. 
Communications Layer 
5.04 This layer takes care of the Message Subsystem software. The 
messages between the processors are sent in HDLC formatted 
packets. The formatting, sending, receiving, and unpacking of these 
messages is handled by the Message Subsystem software. Messages 
are transmitted using a singie 64 kb/s channel in each direction. 
Device Input/Output Layer 
5.05 This layer handles low level details of interfacing to 
input/output devices such as telephony devices and RS-232 
ports. 
Utilities Layer 
5.08 This software layer provides general utilities needed for re- 
source management, error handling, and command interpreta- 
tion 
Applications Layer 
5.07 This software layer exists only in the Main Control Processor 
software. This layer provides the Call Processing which inter- 
prets the Classes of Service, as well as System Abbreviated Dial and 
Personal Speed Dial, Automatic Route Selection, etc. 
Main Control Processor Software 
5.08 The Main Control Processor software is responsible for control- 
ling all activities in the SX-200@ DIGITAL PABX. It commu- 
nicates with the peripheral processors via the Communications soft- 
ware layer for such things as “origination”, “digits received”, etc. Ap-

							General Description 
plications such as Call Processing, Customer Data Entry, and Main- 
tenance management are provided for in the Main Control Processor 
software. 
Peripheral Control Processor Software 
5.09 The peripheral processors handle tasks that are real-time in- 
tensive, such as debouncing switchhooks, collecting rotary dial 
pulses, tone cadencing, and signaling on trunks. The peripheral pro- 
cessors are also responsible for monitoring hardware activity, such as 
cards being added and removed, and reporting all events to the Main 
Control Processor via the Message Subsystem. 
Database 
5.10 The Call Processing software is stored on floppy disk. Upon 
system power-up, the disk data is transferred to the Main Con- 
trol Dynamic Random Access Memory. Customer Data Entries are kept 
on floppy disk for retrieval in case of major system failures. Other 
system information such as flash hook timing, trunk timings, and rotary 
digit translation for different countries, is routed to the Peripheral 
Controi systems for processing.

6. CONFIGURATIONS 
General 
6.01 
The SX-200@ DIGITAL PABX is available in a 480-port configu- 
ration and a 336-pot-t fully digital configuration. In either con- 
figuration, the PABX can be expanded modularly from a basic to a 
full 
configuration. 
6.02 SX-200@ 
DIGITAL PA8X 480-Port Configuration - The 
SX-200’ DIGITAL 480-port configuration, with either Generic 
1000 or Generic 1001 software, has six configurations in either one or 
two cabinets. In the Control cabinet, the digital Control shelf has Bay 1 
on the left and Bay 2 on the right; the optional Peripheral shelf is Bay 
3. In the Peripheral cabinet, the lower and upper shelves are Bays 4 
and 5 respectively. The configurations are: 
Bays 1, 2 Control shelf (digital) only (single cabinet) 
Bays 1,2,3 Control shelf plus Peripheral shelf (single cabinet) 
Bays 1,2,4 Control shelf and lower shelf of Peripheral cabinet 
Bays 1, 2, 4, 5 Control shelf and both shelves of Peripheral cabinet 
Bays 1, 2, 3, 4 
Control shelf plus Peripheral shelf, and lower shelf 
of Peripheral cabinet 
Bays 1, 2, 3, 4, 5 Control shelf plus Peripheral sheif, and both shelves 
of Peripheral cabinet 
The maximum ports available for each configuration, are: 
Bays 1, 2 944 voice/data ports 
Bays 
1,2,3 144 voice/data ports plus 120 voice ports 
Bays 1,2,4 144 voice/data ports plus 120
