4. SYSTEM CONFIGURATION 
General 
4.01 Figures 3-1 through 3-4 show the cabinets which contain the 
equipment bays and the maintenance panels. These units are 
d’escribed in detail in the following paragraphs. 
Equipment Cabinets 
4.02 The 480-port configuration has two equipment cabinets: a Con- 
trol cabinet and a Peripheral cabinet. The 336-port configura- 
tion has one cabinet; the Control Cabinet. The Control cabinet contains 
two digital bays and an optional peripheral...

On-Premises Line Card (ONS) - The ONS contains 12 digital line 
circuits to interface with analog stations located within the same 
building as the DIGITAL PABX. 
LS/GS Trunk Card - The CO Trunk card provides six digital interface 
circuits to interface between the Digital PABX and an analog CO. These 
trunks can be individually set to operate as Loop Start or Ground Start, 
via switches on the card (see Section...

7. PROGRAMMING AND CUSTOMER DATA ENTRY 
General 
7.01 The design and software of the SX-200@ DIGITAL PABX allows 
maximum programming flexibility during installation or when- 
ever a change is required. The features described in Section 
MITL9108-093-?05-NA are enabled or disabled as required at the time 
of installation. Any subsequent changes to the original data may be 
accomplished by reprogramming from a customer’s Attendant Console 
or Maintenance Terminal. Full details of...

8. TECHNICAL DESCRlPTlON 
General 
8.01 The SX-200’ DIGITAL Private Automatic Branch Exchange 
(PABX) is a microprocessor-controlled PABX which uses dis- 
tributed processing and a combination of time- and space-division 
switching. The system uses the PCM (Pulse Code Modulation) form of 
time-division multiplexing as its digital conversion format. The system 
employs b--digital peripheral cards and digitally-interfaced analog 
peripheral cards. 
8.02 The SX-200@ DIGITAL PABX...
