SYSTEM SOFTWARE34.0 System software is classified as either generic software
(operating system) or data base software (site dependent). All
major call-processing functions are performed by the system
generic software, which receives direction from the operating
parameters incorporated into the system data base software.
The software is loaded into the system through a disk drive.
First, a floppy disk containing the generic program is put in the
disk drive and loaded onto hard disk. Next...

l The foreground scheduler consists of a dispatcher that
periodically schedules the following routines:
- Peripheral processor foreground scheduler activation
- System real-time clock update
- Outpulsing DTMF and MF tone
- Sending CAS audible tone identification
l The background scheduler consists of a dispatcher that
schedules routines that perform the following:
- Check for lOO-ms, 500-ms, l-second, and l-minute
scheduled jobs.
- Process events including line- and trunk-status...

Attendant34.1.4 The Attendant Console/Agent Instrument control
Console Controlsubprogram performs the following operations as required by the
Subprogrambackground scheduler:
l Analyzes the status of the Attendant Console and Agent
Instrument pushbuttons as reported by the peripheral
processors’ status-handler routine.
l Causes the appropriate lamps on the Attendant Console and
Agent Instrument to light.

Subprogram
e Memory-reload routine
- Reloads information into the system’s generic and data base
memories when the system is initialized or on a return from
a power failure.
- The routine is resident in the ROM on the system CPU card
and, when activated, reloads all of the software data base.
- The memory reload function in the peripheral processor is
controlled by the on-line central processor.
e Disk routine

Message Detail34.1.13 MDR (Message Detail Recording) provides the means
Recordingfor recording cat1 information pertaining to incoming and outgoing
Subprogramtrunk calls. As the trunk calls proceed through the system, MDR
obtains various pieces of information about the calls. MDR
analyzes this information and stores the results in a call record
block. The call record block can then be sent to one of several
terminal devices. Call record blocks can be output via one port
of the FB-20992-A NSDC (Narrow...

.16 This Integrated Featurephone subprogram processes
responses received from the connected Integrated
Featurephones. Cross-correlation between Integrated
Featurephones, their associated line complements, and the
system line-directory numbers is performed, and the event is
sent to the CPU. This handling subprogram also initiates control
of associated Integrated Featurephone...

TL-130500-1001--For example, refer to the Line Data (LD) Record Code
Assignment Data Sheet (Figure 34.1) and note that above the file
and card position entry header (columns 18, 19, and 20) are
the table references T2541, 
T2551, T2561, and T2571.

Next, look up the table in the actual listing (Table 34.2), for
example T2541 (PEC 0). Note that each table in the listing
consists of two parts, a page with the descriptive details of the
table (header), followed by the page (or pages) of the actual
address structure and the data contained in each address
(resulting from the data base programming).
The descriptive information indicates that “This table provides the
hardware position of each equipped line card, determines the

The use of T tables by the system CPU now becomes more
apparent. As described earlier, the line and trunk circuits are
scanned by the MPB85 cards in the same file; therefore, the card
position and file must be known in order to perform the scan
routines for lines and trunks. The CPU processes all calls using
software IDS. When a request for service is detected during a
scan, the system receives sensing data, which is then compared
with data in the T tables as a means of searching for a...
