LINKED CAPACITY PLUS OVERVIEW
 Combines all the benefits of IP Site Connect and Capacity Plus
 Adds CAPACITY to existing IP Site Connect (IPSC) systems
 Adds COVERAGE to existing Capacity Plus (Cap+) systems
 No central controller needed




Logic is managed in a distributed fashion like Cap+
Does not use a dedicated control channel
Resilient to channel interference
Suitable for shared channels
 Repeaters (Peers) / sites connected via an IPv4 based network like IPSC
 Linked Capacity Plus (LCP) requires more bandwidth than IPSC
 Consists of up to 5 sites (15 sites - future release)
 Up to 6 trunked (voice and data) & 3 data revert repeaters per site
 Same number of repeaters per site not required
 Tolerates failures by design
 The Master repeater is the single point of failure, however this single point
of failure is limited only to the arbitration of IP addresses

Features - Data
 LCP data is similar to Cap+…




Radio to Radio data is always on a trunked channel
Server to Radio data is always on a trunked channel
Radio to Server data is either on a trunked or data revert channel
Radios share the revert channels
 LCP data is similar to IPSC…
 Supports both local and wide area data revert channels
 A wide area / local setting is configured into all data revert repeaters
 A wide area data revert channel is formed by multiple data revert channels (one per
site) sharing a common Channel ID
 Initially, LCP supports server data via Control stations ONLY
 In the future, LCP will also support server data via the repeater IP interface

Features
LCP does not support…
 Priority Queuing of Calls
However, where all system channels are busy:


Emergency calls are able to clear down existing calls using transmit
interrupt (if necessary).
Additionally, supervisors can clear down existing calls using transmit
interrupt (Remote Voice De-key).
 Priority Monitor*
However, this is supported for All Call and Emergency call
 Subscriber Access Control
However, this will be supported in a release later this year
(* this is the ability for radios to leave a call in progress to join a higher priority call)
PAGE 8
LINKED CAPACITY PLUS OVERVIEW
System Loading
 An LCP system handles Local calls as efficiently as Cap+, therefore if all calls are Local, T
= the sum of the number of radios supported by each individual site.
 The number of radios supported by a given LCP site = the number of radios
supported by a Cap+ system having the same number of trunked channels.
 If there are Wide Area calls, T is estimated by first estimating R for a Cap+ system having
N trunked channels.
 If all calls are Wide Area, T = R.
 If there are a mixture of both Local and Wide Area calls, T = R*S (L + (1-L)/W)
 Note:






T = Total number of Radios supported by LCP system
R = Number of Radios supported by Cap+ system
N = Number of trunked channels at the smallest LCP site
S = Number of LCP Sites
W = Average number of Sites associated with Wide Area Talkgroups
L = Number of Local calls as a fraction of the total number of calls
PAGE 9
LINKED CAPACITY PLUS OVERVIEW
System Loading Example
 For a 5 site system where each site contains 12 trunking channels:
 Assume the loading for a 12 channel Cap+ system = 1,200 radios
(note: this corresponds to low voice, low GPS & 5% GoS).
 If all calls are local, LCP loading = 1,200 x 5 = 6,000 radios
 If all calls are wide area, LCP loading = 1,200 radios
 If 40% of calls are Local and Wide Area calls are setup over an average of 3 sites, LCP
loading = 1,200 x 5 ( 0.4 + (1 – 0.4)/3) = 3,600 radios
PAGE 10
LINKED CAPACITY PLUS OVERVIEW
 Requires a software upgrade of radios and repeaters
 Repeaters must have 32MB of flash memory

* The full LCP license does not support Cap+ channels, so if a repeater needs also to
support Cap+ channels then a Cap+ / Incr. LCP license combination should be
purchased instead.
PAGE 11
LINKED CAPACITY PLUS OVERVIEW
Backwards compatibility with Cap+
An old (non-upgraded) Cap+ radio will only operate on a single LCP site. However, its
ID must still be unique across all sites for the LCP system.

Site 2
(1) Old radios can neither make nor
receive Wide Area Individual Calls
(2) Old radios can receive incoming audio
targeted to a Wide Area TG but can
not transmit audio to a Wide Area TG.

Considerations
1)
Master repeater - Must have a static IPv4 address
Peer repeaters (and RDAC applications) - Either static or dynamic IP IPv4 addresses.
2)
Since LCP repeaters at a given site use IP Limited Broadcast address messages to communicate among
each other, then:
 All repeaters pertaining to a given site must be behind a single Ethernet Switch/Router
 The only devices that can be on the site’s LAN are the repeaters pertaining to that site (and any
RDAC applications)
 Hairpinning routers generally* do not need to be used
3)
Refer to the System Planner for details on recommended Switches/Routers. For constructing a small
Linked capacity Plus demo system, the “NETGEAR WNR1000” Ethernet Switch/Router is
recommended.
4)
Refer to the System Planner for details on how to calculate the bandwidth requirements of the backend
network.
*
A Hairpinning router must be used at a site if that site contains multiple LCP devices and one of these
devices is either a Master repeater or an RDAC application.
PAGE 19
LINKED CAPACITY PLUS PROCEDURES
 A Wide Area Talkgroup call goes out on it’s (CPS configured) associated sites and only
starts if channels are available at all associated sites.
 A configurable number of channels at each site can be reserved for Wide Area
Talkgroup calls).
 A radio tries up to 3 times to setup a call with random delays inserted in between each
attempt.
 An Individual call setup goes out on all sites where a channel is available.
 These sites all attempt a high-speed handshake (called “RTR”) with the target radio.
 The site that succeeds with the high-speed handshake and the site where the
initiating radio is located remain in the call while the other sites drop out (i.e.
Dynamic selective site light-up).
 The high-speed handshake occurs concurrently with the call set-up, so no additional
delay.
PAGE 20
LINKED CAPACITY PLUS PROCEDURES
 “TRT” in Cap+ restricts the effect of collisions.
 “Arbitration” in IPSC ensures that all the sites select the same call.
 LCP improves and combines these two processes into a single process called “TR-A-RT”.
 “TR-A-RT” can manage and allocate the channels for up to 5 concurrent calls (each
occurring at separate sites) in one arbitration.
 The Wide Area Call setup time for LCP is approximately 240 ms more than for Cap+ (this
increases where more than 2 concurrent calls need to be allocated).
 The Local Call setup time for LCP is same as for Cap+.
 A radio can receive a Digital Telephone Patch Call on any site, however a radio can only
initiate a Digital Telephone patch call on a site connected to an APP (i.e. a radio can not
initiate a Digital telephone patch call via an APP connected to a different site).

LCP only uses impolite channel access for
emergency calls (where necessary).
When a repeater detects an impolite call it
updates the system call status to the new call.
LCP frees up channels at associated sites (if
necessary) during an emergency call setup.
The start of an emergency call is announced over
all busy channels at all associated sites, thereby
allowing radios to leave their current calls and
join the emergency call (where applicable).
After setting up an emergency call, if there are no
free channels left at a site then the busy rest
channel shifts to a channel where there is a non
emergency call in progress (thus ensuring that
one emergency call does not clear down another
emergency call).

Roaming




To minimise the amount of Beacon signalling
 An LCP (Roaming) Beacon is appended to every 5th Cap+ (Lost Signal Detection) Beacon
To facilitate faster scanning
 The Rest Channels at all the sites synchronise their Beacons
 The LCP (Roaming) Beacons at a given site contain a list of Rest Channel IDs for that site’s
neighbouring sites
Radios use the list of Rest Channel IDs for a site’s neighbouring sites to determine which channels to scan
when trying to roam using either Passive or Active Site search
The list of neighbouring
sites for each site is

PAGE 23
LINKED CAPACITY PLUS PROCEDURES
Roaming – Passive Site Search (Automatic Roaming)
 Radio builds up sorted roam list based on the LCP (Roaming) Beacons transmitted on the
home site’s Rest Channels.
 If home site signal strength drops below a programmable threshold, radio starts to scan
through sorted roam list for a new site
 Radio only scans for a new site while in the idle state.
 Also, the radio does not scan for new site if Site Lock feature enabled.
 During Passive Site search, radio identifies site with strongest signal then makes that site its
new home site.
 Radio remains on the current home site and continues scanning until a better site is found.
 While a radio is carrying out a Passive Site Search, it needs to leave its current home site for
short durations which may cause the radio to miss activity on its home site (resulting in late
entry to voice calls, or missed control/data).
PAGE 24
LINKED CAPACITY PLUS PROCEDURES
Roaming – Active Site Search
 Radio sends wake-up messages to each site in sorted roam list until it finds an active site.
 Active Site Search is initiated if
 a radio initiates transmission and it’s home site rest channel repeater can not be woken,
 or a user initiates a Manual Site Roam (using the menu or a programmable button).
 On waking a repeater, the radio synchronises itself with the repeater, completes the
transmission and makes the new site its home site.
 If the end of the sorted roam list is reached and a site is not found, the radio provides the user
with a failure indication.
 Active Site Search does not necessarily find the best site, but rather allows the radio to move
to the next “in range” site.
