3.6.14 The Property Management System Interface card
connects the system to the PMS. This card communicates with
the PMS using its PMS port and with the 
OMNI PABX using its
KEDU port on the SIDML card, FB-17209-A. The PMI card
provides for an interface to the system hotel printer via its printer
port and the SIDML card. The PMI card fits into any universal
card slot and its external connections are made to the CDF...

TL-130500-1001S1DMLFB-17209-A3.6.17 The SI Dual Modem and Current Loop card has two
circuits and is required for the system to interface with the
following:
l Agent Instrument
l Printer
l KEDU (Key Entry Display Unit)
NOTE: A Line Interface card circuit is also required to interface
with an Agent Instrument. One or two line interface circuits are
used for each Agent Instrument, and two circuits are always
required for the supervisor’s Agent Instrument.
The 
SIDML card connects the Agent Instrument to the...

FB-20996-A3.7.2 The Power Fail Transfer card is required when provisions
for power failure trunks are required. This card connects up to
seven dedicated line/trunk circuits directly to the DDD network on
power outages.
During normal operation, the switch on the front panel of the PFT
card should be in the upward or horizontal position. Setting the
switch in the downward position results in a forced transfer of the
seven trunks on the corresponding relays...

SYSTEM HARDWARE4.0 This section describes the OMNI SI system hardware.
Common Control4.1 The system uses an INTEL 8085 microprocessor as
Hardwarethe master system control device. The INTEL 8085 and other
associated circuitry are mounted on a PCB called the CPU
(Central Processor Unit) FR 17288-A, Figure 4.1.

In addition, there are also status and control signal leads, and
priority interrupt leads complementing the CPU.
The system is equipped with an Ml MB memory card. The 1 MEG
memory is divided into Instruction Pages and Data Pages O-7.
The MPG16 paging card, under software control, determines
which page should be active and sets it accordingly.
The CPU also uses the adddress and data buses to
communicate with other 
PCBs. The CPU connects to the MPB85
card to perform common control functions...

For example, a loop trunk circuit card has four identical circuits.
The MPB85 card addresses each individually. When one of the
trunk circuits detects an incoming seizure (ringing), it changes
the status of a gate (lead 6) on its sense bus. When the MPB85
card requests a read of that circuit, the sense/read bus (lead 6)
reflects this change of status. The MPB85 card accepts this
information as a change in status of sense bit 6 of an 8-bit
digital word, passes this information on to the...

TL-130500-1001Call Processing4.3.1 A basic call, which uses information memory, channel
memory, and control memory (A), is processed as follows:
1. The system scans every line for an off-hook condition, and
finding one (assume phone number 
83) reports it to the CPU.
2. The system writes the location number of that phone into an
unused location in the channel memory (time slot); assume
time slot number 3 (Figure 4.5). At the same time, the system
also reserves time slot number 3 in control memory.
3. The...

TL-130500-1001Call Processing4.3.2 Data is passed between the connected users (stations 83
Data Transferand 55) in the following manner:
1. The network scans through each time slot in the information
memory.
2. For every time slot that has a written phone location, the
network goes to that location, gets a data sample, and writes
the sample into the same time slot in the information memory
3. The network, after doing the data collection for phone 83, looks
in the same time slot in the control memory...
