							TL-130500-1001H/HC (HOTEL/HEALTH19.0 The H/HC printer provides hard-copy records of the
CARE) PRINTER
H/HC services. Any combination of outputs from the message
metering, room status, do not disturb, room restriction, message
waiting, and wake-up features can be obtained on the 
H/HCprinter. Each of these six features can be selectively controlled
to print whenever the feature is activated and/or deactivated (from
any authorized control point), or whenever a print command is
issued from a KEDU.
The system can support up to two 
H/HC printers. This provides
hard copy for related services and activities . Examples of the
printer applications are:
l Cleaning service operations where room status print-outs
provide records of maid service activities (required, in
progress, and complete).
l Front desk where a print-out is required to advise when maid
service is finished and a room is available.
l Accounting department where a continuous audit record of all
message metering is required.The checkout/billing area may
only want this information on request (from a KEDU) for guest
billing/receipt purposes.
Typically, a narrow 40-column printer manufactured by Axiom
(Figure 19.1) is used for the 
H/HC printer applications; however,
a wide 80-column format can also be used. Data properties of
either 110 or 1,200 baud, odd/even parity, one- or two-stop
bits, and seven- or eight-bit words can be specified. This
allows almost any printer to be used as long as it is 20 ma.

H/HC
Printer/System19.1 The printer interfaces with the system via the 
SIDML card,
located in a PCMUS slot.
Interfacel The card provides a 20ma transmit circuit to the 
H/HC printer.
l A single simplex data pair from the card supports the printer.
l The printer is slaved to the system.
NOTE: For description of the SIDML card, see paragraph 3.6.17.
Power for the 
H/HC printer typically comes from a local 115 VAC
power outlet .

							MAINTENANCE
TERMINALMaintenanceTerminal/System
InterfaceSVR 5210TL-130500-1001
20.0 The maintenance terminal records system traffic
data and system faults and provides the means for performing
data base changes and requesting maintenance procedures and
diagnostics. The system uses a TTY printer or video display
terminal as a maintenance terminal. The maintenance terminal
can be equipped with a printer when a hard-copy print-out is
required.
20.1 The maintenance terminal interfaces with the system via
one port of the FB-20992 NSDC (Narrow Serial Device
Controller) card, located in slot 6 of the Get Started File.
NOTE: The NSDC card is described in paragraph 3.4.7
The NSDC card is a programmable serial device controller with
two full-duplex ports, designated port 0 and port 1. Each NSDC
port can be manually configured for a 20-ma, 12 volt, current
loop or RS-232-C operation mode. Under software control,
each NSDC port can be individually programmed for baud rate.
The NSDC port is addressed via the CPU address bus and data
is transferred between the maintenance terminal NSDC port and
system CPU via the CPU data bus.
If the maintenance terminal is a TTY, the associated port on the
NSDC card is configured for 20-ma current loop operation. If
the maintenance terminal is a printer or equivalent EIA
(Electronic Industries Association) compatible device, the
associated port on the NSDC card is configured for partial
RS-232-C operation. Modems are available for remote TTY or
terminal operation.
Maintenance terminal power connections, cabling, and
installation procedures are described in TL-130300-1001.
The following characteristics are needed to interface a CRT or
TTY to the system:
* EIA RS-232-C communication
e ASCII character set.
0 Full- or half-duplex operation
@ Baud rate of 110, 300, or 1,200
0 Display format of 24 by 80 characters

software and common system hardware. The software
HARDWAREassociated with the MDR feature uses common or shared
memory.MDR Printer/21.1 The MDR printer interfaces with the system via one port
System Interface
of the FB-20992 NSDC (Narrow Serial Device Controller) card
located in slot 6 of the Get Started File.
NOTE: The NSDC card is described in paragraph 3.4.7.
The system can only support one NSDC card (two ports). The
MDR output records can be transferred to external equipment
through either serial port 0 or serial port 
1. Manual switches on
the NSDC card allow these two ports to be selected individually
for RS-232-C mode or 20-ma current loop mode. Under
software control, each port can be individually programmed for
baud rate, character length, parity checking, synchronous or
asynchronous operation, number of stop bits, and interrupt
capability.
l Port 0
- interfaces to a local or remotely located TTY or similar
terminal which provides a hard copy of MDR records
- controlling software output does not react to control signals
from the TTY
-MDR output is provided independently of the condition of the
receiving TTY
With the use of port 0, the system works on a real-time basis
(i.e., the call records are printed as they become available).
Header data is output whenever a system start occurs, when a
change in date or time occurs, every 
64/32 call records or upon
command from the administrative facilities (64 call records for
single-line output or 32 for double-line output). The call record
is output whenever an assembled call record is available and is
in single format. The data base programmable output rates are
110, 300, and 1200 baud.
0 Port 1
- typically configured for RS-232-C operation
- interfaces to a minicomputer or remote polling device
- MDR output format is the GTE-modified EBCDIC (Extended
Binary Coded Decimal Interchange Code) shown in Table
21 .l.SVR 5210
8187S-257 
						

							TL-130500-1001
NSDC card port 1 output is programmed to transmit data at
speeds fast enough to avoid loss of data under the heaviest
traffic conditions. The baud rates are 110, 300 and 1200. The
baud rate and other options are programmable in the 
office-dependent data base.
When selecting the speed for the output device from MDR port 0
or MDR port 1, the amount of traffic being handled by the system
must be considered. The MDR file is capable of buffering a fixed
amount of call record blocks, after which the additional call
information is completely lost. Therefore, the worst case peak
traffic must be considered, along with work group and trunk
group screen options. These factors will determine the
probability of losing a call record block.
The MDR is capable of buffering 12 call record 
bloc::s (132
calls). As each call record is output by the MDR, an additional
call record block can be generated and the data saved for
output. If, however,
72 call record blocks are already in use at
the time another call record block is generated, the data in the
block 
will. be lost for output to that port. The speed of the TTY or
other output receiving device must therefore be chosen so that
call record blocks are not lost. Cabling for the MDR is described
in TL-130300-1001. Figure 21 
.l shows a typical MDR
configuration.
NOTE: When a call block is lost, no indication of the loss is
provided, nor is there any means to recover the data.
