SYSTEM SALES, DESIGN, INSTALLATION and MAINTENANCE
Where
the technology stands today!
DMR Tier 3 products are now available. DMR (Digital Mobile
Radio) has become the most popular digital PMR protocol, largely due to
its Mode 2 product success seen in recent years. Tier 3 is the fully
trunked version providing true trunking features with managed resources
and intelligent queuing. DMR has quickly become the No1 choice for
migration from other systems.
DMR - 100% digital TDMA technology, designed to operate two time
slots within existing 12.5kHz channel spacing. DMR meets
FCC regulatory requirements for 6.25kHz channel equivalence.
DMR was developed and ratified by (ETSI) European Telecommunications
Standards Institute.
DMR
Tier III: Fully Trunked
DMR
Tier III covers trunking
operation
in frequency bands
66-960MHz. The
Tier III standard specifies
two-slot
TDMA in 12.5kHz channels.
Tier III
supports voice and short
messaging
handling similar to MPT-1327
with
built-in 128 character
status messaging and short messaging with up to 288 bits of data
in a variety of formats. It
also
supports packet data service
in a
variety of formats,
including support
for IPv4 and IPv6.
DMR
Tier II: Conventional
DMR Tier II covers licensed conventional radio systems, mobiles
and hand portables operating in PMR frequency bands from
66-960MHz. The ETSI DMR Tier II standard is targeted at users
who need spectral efficiency, advanced voice features and
integrated IP data services in licensed bands for high-power
communications. ETSI DMR Tier II specifies two-slot TDMA
in 12.5kHz channels.
DMR Tier II products are commercially available today.

Hytera
DMR Tier III Compatible
|
|
Multi-Lingo controller and the Hytera
985s Repeater have intelligent interconnect offering scalable
DMR Tier III trunking systems
capable of
cross protocol communications and seamless
migration possibilities from legacy systems.
Hytera have become the manufacturer to follow when it comes to subscriber unit
design providing user-centred ergonomics, long battery life and essential features.
All Hytera DMR products fully meet ETSI DMR European Telecommunication Standards
Institute (ETSI) standards.

Over
the past 3 decades Fylde have supplied and supported over
4000 radio networks. SYSCON is the network operation and
management terminal that controls and monitors these systems.
For MultiLingo, Fylde has developed an entirely new product
built to give the network operator the ultimate power and
flexibility necessary to run a modern system efficiently.
Next
Generation SYSCON-Suite™
The in depth network control that Fylde’s SYSCON is renowned for has evolved,
now providing management and monitoring
of your system using a secure IP connection
from a common web browser session.
Syscon-Suite offers integrated
applications such as a SIP based dispatcher
and asset tracking all via a web browser.
Multi-Lingo System Specification
Multi-Lingo
can be used to build systems ranging
in size from 2 channels on a single
site to national systems of over
1000 sites. Each Multi-Lingo tray
supports either 4 x DMR timeslots,
4 channels of dPMR or 4 channels
of MPT1327. Trays can provide a mix
of protocols up to 32 channels per
site.

| No
other Fylde components required to
make a system. ** See (RCS) note > |
| Each
1u / 44mm height chassis supports 4
time-slots |
| Up
to 32 time-slots per site |
| Up
to 1000 sites networks across multiple
regions |
| Network
supports over 1 Million subscriber
terminals |

Bandwidth Optimisation
**(RCS) note
| For
larger networks of over 5 sites it
is recommended to use a separate (RCS)
Regional Control Server. The separate
RCS further optimises IP radio network
traffic by arbitrating subscriber registration
data. |
