1. Overview of Fylde MPT1327 Trunking Equipment & Features OR
“What box do I need to do that?”

2. Let’s build a single site system
Step 1: First I need a repeater...
Step 2: But for it to be trunked,
I need a TSC. One TSC03 supports up to 4 channels
Step 3: But for it to be really useful
I need more channels, say 3
Step 4: If I want user validation
& system management
I need an SCI
Step 5: and because I have an SCI,
I need Syscon NT
Step 6: If I need local Teleconnect,
add a PCM switch

3. But what about more sites?
Syscon NT
Internet-
Message Handling Dispatcher x 16
Regional Node
PSTN x24
PABXx24

4. RAIL/PIPELINE APPLICATIONS x10 x23 x23 x23 x23 x23 PSTNx24 PABX x24
MHD's
PSTNx24
PABX x24
x23
x23
x23
x23
x10
x23

5. Inter-Regional Processor x5 x16 PABX x24 PSTNx24 PABX x24 PSTNx24

6. NETWORK SUMMARY REGION = SITES x 10 INTER-REGION = REGION x 16
NETWORK = INTER-REGION x 5
SYSTEM CAPACITY
TOTAL SITES = 10 x 16 x 5 = 800

7. The TSC02 One TSC per RF channel
Same hardware for Control Channel and Traffic Channel(s)
Indication of channel state:
- RF channel No., Transmit, talkthrough
Indication of channel faults:
- TX power FWD / REV, receiver, line interface

8. The TSC03 But what does it give me?
One TSC supports up to 4 RF channels
Flash Programming an Configuration from P.C
Built in optional LIFU
Built in Scope for line monitoring
But what does it give me?

9. With just a TSC you get…
Normal and Emergency speech and non-prescribed data (NPD) calls
Status calls
Short Data Message (SDM II)
With more than one channel - call queuing for channel
With more than one channel - queuing for 'called party busy'
Set of default control parameters (timers etc) stored in EPROM
Monitor various alarms and provide visual indications of status
Indication at front panel only

10. What don’t I get? Validation of radios individually
everyone is 'white-listed'
A record or billing of the calls made on the system
Statistics of calls made on the system
Intersite calls
including line-dispatcher, PSTN, or PABX calls
Call diversion
Connection to the system control or analysis terminal
Syscon NT

11. The SCI So why bother? One SCI per base station site
Interfaces to the outside world
Configuration data held in EPROM
Billing records held in SIMM RAM Module:
- subscriber validation, billing data, control parameters
I/O’s from site:
- 5 analogue inputs, 2 logic inputs, 5 logic outputs
So why bother?

12. Because you get this... But you need Syscon NT
Validate radios individually
everyone is now 'black listed' until they have a record
Call records are stored on a call by call basis
Call statistics are compiled over a rolling 24 hour period
Control parameters can be altered via Syscon NT
System alarms are presented to Syscon NT
Rack temperature displayed on Syscon NT
Auxiliary monitoring and output drivers available for custom use, accessible via Syscon NT.
Multi-site operation is possible
But you need Syscon NT

13. What if I want more than one site?
SYSCON NT Software
Network Management Platform
Runs on a PC under Microsoft Windows NT
Open MS Access format
Individual subscriber management
Time-tagged control parameters
Variable individual and user-group facilities / priorities
Dynamic call timers
Call billing
Traffic statistics
Remote alarm and maintenance facilities
Multi-language support including Chinese
What if I want more than one site?

14. RCP (Regional Control Processor)
One RCP per 10-site region
Connects to the SCI at each site
Acts as data routing device
for call set-up and radio movements etc
Provides gateways to PSTN / PABX
Provides access to PC based dispatchers (MHD)
It gives you...

15. All this! But it’s no use without...
Gateway to the PSTN via a maximum of 24 lines
Gateway to up to 8 PABXs via a maximum of 24 lines
Access to 16 PC-based line connected dispatchers
Call Diversion
Pooled Channels (frequency sharing) Use with Caution!!
An expansion port to the INTER-REGIONAL PROCESSOR for very large networks of up to 160 sites
But it’s no use without...

16. PCM Switch Controlled by the RCP Serves for the switching of speech
- between sites
- to PSTN / PABX
- to dispatchers
Each card has four ports
Each card supports:
- 2 wire
- 4 wire
- E & M
- 2/3 wire telephone working
(Two ports per card only)

17. What does the PCM switch do?
Switching of speech (or non-prescribed data) between
radio sites, line dispatchers, the PSTN, or PABXs.
No call set-up logic in the switch, as such
but it does provide intelligent processing to interface with phone systems etc e.g.
E & M interfacing and DTMF dialling.
10 i.p.s. (dial click) dialling available outbound only.
All common 2-wire and 4-wire analogue private circuits.
Built in barriers and interfaces
Can I have a line based dispatcher?

18. (Message Handling Dispatcher)
YES you need a MHD
(Message Handling Dispatcher)
PC based operator position with voice control unit
Up to 16 terminals can be connected to a regional system
Can make voice calls and stack incoming calls
Allows the transmission / reception short data messages
Runs under Windows 95/98/NT
Needs RS-232 link to RCP & audio connection to PCM switch
MHD is also the internet gateway for to the radio fleets

19. Call Types Individual speech call Group call Emergency call
Radio  PSTN / PABX calls
Call diversion
Data call
- Status and SDMII (over Control Channel)
- Non Prescribed Data (over Traffic Channel)
PABX
PSTN

20. ...and all in about 427ms seconds!
Call Set-up
1. CC invites call requests (ALH)
2. RU1 sends call request for RU2
3. CC Ahoys the call request (AHY) - ACK for RU1 - AHOY for RU2
RU1
4. RU2 confirms availability (ACK)
RU2
5. CC sends Go To Channel message (GTC)
CC ... Control Channel TC ... Traffic Channel RU ... Radio Unit
6. Radio units may speak (TC)
...and all in about 427ms seconds!
