 Technical Description |


The DT-2000 features
a flexible, multi-protocol design for
single site & multi-site trunking
networks
Version 2.0
VDV Medias DT-2000 Digital
Trunk Switch has been designed to
meet your trunking and
interoperability needs for today.
As you migrate to digital
solutions, it can grow with you.
The DT-2000 is designed to
provide connectivity and
compatibility to all the
resources within the switch as
well as to the network.Because
it is a digital TDM switch, it
allows flexibility in resource
management and in the switch to
make use of a wide choice of
resources. This would include a)
an 800Mhz trunking radio can talk
to an UHF trunking radio. b) A
VHF conventional radio can be
cross-banded to an UHF trunking
radio. c) Any radio can have
access to any phone line or any
network link on the system. d)
Outbound calls can be connected
directly to a phone line or to a
network link. e) If there are
multiple DT-2000s networked
together, any radio on a switch
can be connected to any radio on
another switch or to any phone
line. It is truly a non-blocking
digital matrix switch.
The DT-2000 Digital Trunk
Switch can support 20 repeater or
radio interfaces and can be
expanded to support 40 repeater
interfaces at 800Mhz, UHF, VHF
high band land low band. The
system is designed with the
advanced DSP, TDM digital
technology and it provides
non-blocking switching, COR, PTT,
RSSI capability. Each Radio
Interface port can handle
multiple radio groups to simplify
system design and reduce cost.
Automatic call setup and routing
capability will allow easy to use
and efficient communication
network. Using its cross-banding
technology, the DT-2000 Digital
Trunk Switch can provide
connectivity between different
protocols and different
frequencies making them part of
the overall network. Dispatch
calls between radio groups can be
preprogrammed and set up in
advance or can be programmed by a
radio with DTMF on the fly.
When coupled with the MSD
Multi-Site Dispatch Hub, the
DT-2000 will support multi-site
dispatch between 2 and 32 sites
in a true Transmission Trunked
mode.

COMPONENT
DESCRIPTIONS:
DT2000-6
or DT2000-20 - Basic Switch
The basic
DT-2000 is designed to support
either 6 or 20 repeaters and can
be upgraded to support up to 40
repeaters. It is configured in a
19" rack with the Digital
switch including 12.1" TFT
monitor, keyboard, touch pad, CD
Rom, hard drive and Switch
software supporting LTR Protocol,
Data Network and Network
Dispatch, Windows 2000. Also
included is a Repeater Control
Card (6 or 20 port) and a Telco
Interconnect Card (8 slot).
DT2000TEL
Audio Interconnect Card
This is an
Audio card with 8-port capability
to provide connection to the PSTN
or to the wide area network. The
DT2000TEL requires a Loop Start
or E&M hybrid module for each
port to provide audio
interconnection.
DT2000LS -
Loop Start Network Module
Hybrid Module
that allows interface to POTS
lines.
DT2000EM -
E&M Network Module
This Hybrid
Module allows an interface to 2
wire or 4 wire E&M lines. To
support 4 wire E&M interface,
2 modules are required. This
hybrid module also supports DID
interface.
DT2000E1 -
E1 Telco Card (30 port)
Telephone
card designed to support the
international standards for
delivering 2 Mbps or 30 phone
lines from the Telephone Company.
The system also supports
fractional E1.
|
|
DT2000T1 - T1 Telco
Card (24 port)
Telephone card designed
to support the US standard for
delivering 1.54 Mbps or 24 phone
lines from the Telephone Company.
The system also supports
fractional T1.
DT2000LRB -
LTR Repeater Logic Board
This is the
interface board to connect the
LTR repeater to the DT-2000
through the Repeater Controller
Card.
DT2000CRB -
Conventional Repeater Logic Board
This is the
interface board to connect a
conventional repeater/radio to
the DT-2000. This board will
support all the CTCSS
tones/groups.
DT2000CRB1 -
Radio Logic Board
Designed for
proprietary radio interface, this
will handle one group.
IP Network
Gateway (2 or 4 ports)
This will allow
DT-2000 system to send voice
through IP Network (VoIP). This
option has Ethernet Interface and

|

CALL TYPES SUPPORTED:
|
Local Dispatch Call
Through the use of a
half duplex radio, the user keys
the microphone (Push to Talk-PTT)
and the system collects all the
radios with the same group to
participate in conversation.
Multi-Site
Dispatch Call
Through the use
of a LMR radio, the user keys the
microphone (Push to Talk-PTT) and
the system collects all the
radios in the network sites (2
32) that have been defined
to participate in the
conversation. These calls are
transmission trunked, thus
maximizing the RF system
resources of the network.
Cross
Trunked Dispatch Call
Calls can be
set up and made by radios of
different frequencies and
different protocols thus
providing True Interoperability
between different radio systems.
This can be set up in advance or
can be made dynamically done by
radios with DTMF capabilities.
|
|
Direct Connect Call
Through the use of the
DTMF pad, a user of a half duplex
radio can make a private
transmission trunk call to
another radio.
Selective
Call
Through the use
of the DTMF pad, a full or
half-duplex radio can be patched
to a telephone resource in the
switch to make and receive
telephone conversation trunk
calls.
Call Routing
Calls
originating within the switch can
be routed through the system to
specific phone and network
resources.
Dynamic Call
Set Up
Through the use
of DTMF a radio may dynamically
on demand set up calls between
different radio trunk groups on
the system. These radios may be
of different frequencies and/or
protocols.
