INTER REGIONAL PROCESSOR
DESIGN PHILOSOPHY




Based on industry standard pc hardware.
Industrial specification IBM compatible
computer running Fylde IRP software.
Equipped with a multi port communications
controller.
Built in Hardware Watchdog.
WHAT IS IT?



Allows inter regional expansion for Fylde
trunking systems.
Connects up to 16 regions (RCPs) to form a
wide area trunking network.
Routes audio/data between inter regional radio
sites.
IMPLEMENTATION


Connected to the RCPs by standard RS232
communication links.
Audio can be routed via:
–direct connection of audio circuits between RCPs
–Fylde PCM Switch at the IRP
–both of above
FACILITIES 1

Status Display showing:
–RS232 link status to RCPs
–IRP integrated PCM Switch (if connected)
–Processor Loading
–Calls in progress
–Printer status
FACILITIES 2

Logging Facilities:
–Call Log
–Registration log

Incorporated Registration Database allows:
–reduced system load
–speed up call processing
–De-registration of RU’s
FACILITIES 3

Diagnostic Facilities:
–Node Communications - monitoring of data
messages between IRP and RCP
–PCM Switch Communications - similar to Node
Communications
–Silicon Disk Memory Test - allows testing of the
disk used to store the Registration Database
INITIAL CONFIGURATION

General Program Parameters
–Registration Validity Period
–Maximum Allowable Prefix
–Call Logging Facilities
–Disk Drive for Registration Database
–Disk Drive for logging files
–Call Log page length
–Log Registration Records to disk
–Change Main Password
INITIAL CONFIGURATION

Configure the RS232 links from each region
–baud rate
–No parity / 8 data bits / 1 stop bit


Configure the PCM Switch
*EVEN IF NO PCM SWITCH IS PRESENT*
–communications port on the IRP pc
–link baud rate (usually 9600)
–PCM Switch Patch Map
IRP PATCH MAP 1

Determines the audio inter connect between
sites and regions, by either:
–routing audio circuits through a PCM Switch
– direct connection which does not require a PCM
switch. Used for low capacity networks
–both above options
–Can only use direct connection with Inter-Regional
group calls on 2 region systems.
IRP PATCH MAP 2



Maximum of 24 (0-23) lines available
Each region has 24 lines available but not the
facility to use them all, at each region
Each region must be configured separately.
IRP PATCH MAP 3

Configuration
–Two parameters for each audio line FITTED and
PCM SWITCH PORT
–FITTED is set YES or NO, indicating whether that
line is fitted to that region
–PCM SWITCH PORT determines the port used
between 1 and 128. If set to 0 (zero) then this
indicates that that line is a direct connection between
RCPs. Blank indicates not fitted.

BOOT OPERATION



Should be run from Floppy Disk.
Use Hard Disk Boot as back up only.
Ensure configuration is the same on both
floppy and hard disk.
