ADVANTAGES OF A BASIC SMARTRUNK SYSTEM

• Can Overlay an Existing Repeater System.
• Easy to Migrate a Conventional System to Trunking
• Decentralized protocol makes it possible to trunk
  frequencies previously used for community
  repeaters
• Can operate in parallel with a shared repeater
  sub audible tone panel during migration of users
• Compatibility with many legacy repeaters and
  radios SAVES MONEY

6
ADVANTAGES OF A BASIC SMARTRUNK SYSTEM

  channel that is inaccessible by other system
  users.
• Once a channel is assigned, users have instant
  PTT style communications.

Voice logging for security purposes

• The system can optionally record any call or
  specific class of calls in a file within the
  ST-510
• Software can choose calls that are to be
  recorded.
• The same software allows the system administrator
  to search and playback a desired call using a
  multimedia PC. A call to be played back can be
  searched by various fields (user, date, time,
  destination, length, etc)

62
SITE TELEMETRY

• Aside from simplifying remote site linking
  requirements, the SmarTrunk ST-100 Multiplexer
  has several Digital and Analog I/Os which can be
  connected to site monitoring transducers such as
  offered by Zetron and others for remote site
  monitoring.

64
Billing Information Service

• A user can listen to his/her usage and bill
• A user can program a usage alarm in order to
  better monitor their bill
• The system operator can set a limit to any users
  airtime (pre paid service)

66
Operator assistance for lost calls

• If an incoming call can not be completed as
  dialed, it can be set to automatically transfer
  to an operator (at a radio, extension or dispatch
  console)
• The operator can then transfer the call to the
  correct user.

67
Call Queuing

• The call manager feature lets the system know
  when a user tries to make a call while all
  channels at a site are busy
• An extra simplex channel with an ST-853 is
  required
• If a user cant access a free channel, the system
  picks up the call request and builds a queue
• When a channel is freed, the system sorts the
  queue by priority and aging and completes the
  call request from the next queued user
• The call manager channel is automatically enabled
  by the ST-510 when all channels are in use

68
Call Manager
If channels are available the Call manager stays
on a sleep state and the mobiles never stop on
this frequency
69
Call Manager
If all the channels are in use, the call manager
wakes up. If any radio tries to make a call,
this channel receives the inquiry and puts it in
a queue

Networking

• A single ST-510 switch can control local and
  remote sites
• Multiple ST-510s can be added for increased
  reliability and less inter-site link traffic.
  Topology flexible
• Flexible Network topologies increase linking
  options
• Multiple ST-510 sites require only one data bus
  between all the network sites and only as many
  audio links between sites as roaming traffic load
  requires

System Breakdown

• Each ST-510 has an industrial CPU
• An ST-422 board is required for each SmarTrunk
  channel
• An ST-422 board is required for each PSTN/PABX
  line
• An ST-422 board is required for each DSP
  channel. Number of DSP channels is determined
  by expected peak time usage of voice services
  (like voice mail, prerecorded messages, billing
  messages)
• An ST-422 board is required for each dispatch
  console
• An ST-422 board is required for each link to any
  other ST-510
• Each switch rack holds eleven ST-422 boards
• Each switch rack has a Power Supply (redundancy
  from other racks)
• The ST-510 switch requires 4 units 19 rack
  space for the CPU and 3 units for each switch
  rack

87
