CP85E3.4.5 The Central Processor Unit card contains an INTEL 8085
FB-17288-Amicroprocessor and associated clock, control, interrupt, and I/O
(InpuVOutput) interface circuits. The 8085 microprocessor
provides both normal switching and MDR functions. The card
controls all operations within the system including:
l Path connect/disconnect within the network
* Data transfer to/from system maintenance terminals
l Data transfer to/from system disk drive
l Communications to/from system...

TL-130500-1001FMSD3.4.8 The File Management System Data card provides an
FB-17220-BOAintelligent serial data interface between the floppy disk drive, the
hard disk drive, the PD-200’s ADMP, and the CPU. Data and
control signals are cable-connected between the floppy disk
drive and FMSD. The FMSD is addressed via the CPU address
bus. Data is transferred between the CPU and the FMSD via the
CPU data bus. This card provides DMA (Direct Memory Access)
and interrupt control to the CPU.
The FMSD contains the...

TL-130500-1001iNCl&3.4.11 The Synchronizable Intermediate Network Clock
FB-20922-A
card (Figure 3.5) provides the basic timing pulses to the system
network and PCM associated circuitry. The INCKS card permits
the system to communicate over 
Tl trunks. In this case, the
system is slaved to the far end of the span. The INCKS card
also contains the network time slot counter.
The INCKS card receives control inputs from, and outputs clock
pulses to, the EPCMN card.

FB-20771 -lA3.4.12 The Intermediate Network Clock card provides all the
functions of the INCKS card, except that Tl’ synchronization is not
possible. This card is used if no Tl functions are used in the
system.
NOTE: Use FB-20922 network clock when network timing is
derived from a 
Tl span (slave operation).

3.4.15 The Pulse Code Modulation Tone Source card stores
samples of the various system tones within a ROM (Read-Only
Memory). Tones read from ROM are transferred to the
information memories for use throughout the system. This
provides the dial tone, 
ringback tone, and other alerting tones
used in the system.
The PCMTS receives control inputs from the Network Clock...

TL-130500-1001Digital Trunking3.5 This paragraph provides information about PCBs that are
Printed Circuitinstalled within the Tl span digital trunk preferred location.
BoardsIn this system, only one Tl span, which has a maximum of 24
channels, can be installed. Only file X can be used for this type
of configuration and only certain slots within that file can be used
by these cards. Not all 
Tl span cards require two card slots.
Card slots C6, 
C5, and C4 may be used even if a Tl span is
implemented....
