6 ’ HARDWARE OVERVIEW General 6.1 The Control Card/Control Card 2 contains the common control circuitry and card slots for the 10 peripheral cards. The peripheral cards communicate with the control circuitry via a common parallel address/data bus. The control circuit includes an 8-bit microprocessor which interfaces through its address/data bus to the following: . l DX Switching Matrix l Digital Signal Processor l Printer Interface l Attendant Console Interface (voice and data) l DTMF Receivers l I/O Interfaces l Memory l Music/Pager/Relay (Control Card 2 ONLY). Refer to Figure 6-l for the SX-50 system block diagram. Microprocessor 6.2 The microprocessor is driven from an 8 MHz crystal oscillator and operates on a 0.5 microsecond cycle time. The master clock drives the interrupt request (IRQ) line. The Attendant Console UART drives the fast interrupt request (FIRQ) line. The reset line (RES) is driven from three sources. The first source (power-on reset) holds the microprocessor in the reset condition until the power rails are established. The second source is the watchdog timer, which causes a reset if not accessed in a given period of time. The third source is a manual reset switch mounted on the Control Card. The reset signal is also routed to all peripheral cards. DX Switching Matrix 6.3 The DX switching matrix includes three DX chips and has the following bidirectional links: l 1.5 links (48 channels) to each peripheral card l one shared link for the digital signal processor and Attendant Console voice l one shared link for the Attendant Console gain control and DTMF receivers. 9104-091-lOO-NA Issue 5 Revision 0 100 6-l

u!A!J Hardware Overview Clot k Signal Generation 6.4 The master clock for the PCM links is 16.384 MHz. All of the other PCM clock signals are derived from this. Digital Signal Processor 6.5 The Digital Signal Processor (DSP) provides 8 channels of dual tone generators, 18 conference channels and one tone detector. Tone Generation. The DSP generates all DTMF and call piogression’tones. Tone Detection. The Digital Signal Processor provides two types of tone detection: dial tone and test tone. Dial tone detection is used to determine trunk readiness for outgoing calls. Test tone detection is required for background testing of channels. Attendant Console Interface 6.6 The Attendant Console data link uses an asynchronous serial interface. The data rate is 4800 Baud. Printer Interface -6.7 The printer interface also uses an asynchronous serial interface’(6551). The following data rates are software-selectable: 110, 150, 300, 600, 1200, 1800, 2400, 4800 or 9600 Baud. DTMF Receivers 6.8 The MITEL codecs convert the PCM signals to analog and route them to the DTMF receivers. The Cbntrol Card contains 5 codec/DTMF circuits. Memory 6.9 All system memory (program memory and RAM) is located on the Generic Module. Refer to the Generic Module physical description in this Section. 9104-091-l 00-NA issue 5 Revision 0 100 6-3

7 . SOFTWARE OVERVIEW General 7.1 The SX-50 system software operates in two independent layers as described below. Call Processing Layer _ 7.2 The Call Processing layer monitors all system activities and implements the features that have been selected. Peripheral Processing Layer 7.3 This Peripheral Processing layer controls the interconnection of all devices attached to the system and feeds status information to the Call Processing layer. 9104-091-lOO-NA Issue 5 Revision 0 100 7-1

8 . FEATURES General 8.1 The features contained in the SX-50 MS55 software package are listed in Table B-1. Section 9104-091-l 05-NA, Features Description, provides a complete description of each feature, including special conditions and programming information. . Attendant Features. Attendant features can be programmed to suit the customer’s application. There are 14 Programmable Function keys on the Attendant Console keyboard and 18 functions that can be assigned. Refer to Section 9104-091-21 Cl-NA, Customer Data Entry, for more information. Extension Features. There are 9 Classes of Service. Each Class of Service (COS) can contain any nonconflicting mixture of features. Each extension and trunk is assigned to a COS which contains the desired features. SUPERSET Telephone Features. Like stations, SUPERSET telephones are each assigned a Class of Service. The SUPERSET 420 can have up to twelve line appearances; the SUPERSET 470 can have up to six line appearances. The SUPERSET 3 can have up to three line appearances; the SUPERSET 4 can have up to fifteen line appearances. On SUPERSET telephones, unused Line Select keys can be used as Sp.eed Dial keys. Refer to 9104-091-210-NA, Customer Data Entry, for programming information. English or French System Messages+ The SX-50 System provides text to the Attendant Console in English or French. Customer Data Entry is available in English only.
