LINKED CAPACITY PLUS OVERVIEWØ 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
Ø No central controller needed§ Logic is managed in a distributed fashion like Cap+
§ Does not use a dedicated control channel
§ Resilient to channel interference
PAGE 2
§ Suitable for shared channels
Ø Repeaters (Peers) / sites connected via an IPv4 based network like IPSC§ Linked Capacity Plus (LCP) requires more bandwidth than IPSC
Ø 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
Ø 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

LINKED CAPACITY PLUS OVERVIEW
Ø 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
Features - Data
PAGE 6
Ø 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
Ø Initially, LCP supports server data via Control stations ONLY§ In the future, LCP will also support server data via the repeater IP interface

Additionally, supervisors can clear down existing calls using transmit interrupt (Remote Voice De-key).
Ø Priority Monitor* However, this is supported for All Call and Emergency call
Ø Subscriber Access ControlHowever, 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)
LINKED CAPACITY PLUS OVERVIEWSystem Loading
Ø 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.
Ø 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.
PAGE 9
§ 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)
Ø 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
LINKED CAPACITY PLUS OVERVIEWSystem Loading Example
Ø 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
PAGE 10
§ 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
LINKED CAPACITY PLUS OVERVIEWØ Requires a software upgrade of radios and repeaters§ Repeaters must have 32MB of flash memory
§ Compatible with current and next generation MOTOTRBO radios
Ø Requires feature activation in the repeater§ HKVN4108A DR 3000 Full license key*
§ HKVN4063A DR 3000 Incremental license key (from Cap+)
PAGE 11
§ HKVN4063A DR 3000 Incremental license key (from Cap+)
§ HKVN4109A MTR3000 Full license key*
§ HKVN4070A MTR3000 Incremental license key (from Cap+)
§ New LCP compatible version of RDAC available
§ GMVN5520F RDAC CD
* 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.
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.

kperiodic site Keep Alive messages.
Start of call setup:Source Rest channel repeater sends one message to each Site IP Address associated with call, and each Rest Channel repeater in call responds such that all repeaters in call learn IP addresses of all other repeaters (at other sites) in call.
Rest channel Master Data Revert Repeaters (Optional)
1) Master repeater - Must have a static IPv4 addressPeer 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)

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.
Ø 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).
Ø A radio tries up to 3 times to setup a call with random delays inserted in between each attempt.
LINKED CAPACITY PLUS PROCEDURES
PAGE 20
Ø 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.
LINKED CAPACITY PLUS PROCEDURESØ “TRT” in Cap+ restricts the effect of collisions.
Ø “Arbitration” in IPSC ensures that all the sites select the same call.
Ø LCP improves and combines these two processes into a single process called “TR-A-RT”.
Ø “TR-A-RT” can manage and allocate the channels for up to 5 concurrent calls (each occurring at separate sites) in one arbitration.
PAGE 21
occurring at separate sites) in one arbitration.
Ø 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).
Ø The Local Call setup time for LCP is same as for Cap+.
Ø 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).

Ø To minimise the amount of Beacon signalling§ An LCP (Roaming) Beacon is appended to every 5th Cap+ (Lost Signal Detection) Beacon
Ø 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 sitesØ 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 searchØ The list of neighbouring
sites for each site is CPS Configurable Interval

Ø Radio builds up sorted roam list based on the LCP (Roaming) Beacons transmitted on the home site’s Rest Channels.
Ø If home site signal strength drops below a programmable threshold, radio starts to scan through sorted roam list for a new siteØ Radio only scans for a new site while in the idle state.Ø Also, the radio does not scan for new site if Site Lock feature enabled.
LINKED CAPACITY PLUS PROCEDURESRoaming – Passive Site Search (Automatic Roaming)
PAGE 24
Ø During Passive Site search, radio identifies site with strongest signal then makes that site its new home site.
Ø Radio remains on the current home site and continues scanning until a better site is found.
Ø 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).
Ø Radio sends wake-up messages to each site in sorted roam list until it finds an active site.
Ø Active Site Search is initiated ifØ a radio initiates transmission and it’s home site rest channel repeater can not be woken,Ø or a user initiates a Manual Site Roam (using the menu or a programmable button).
Ø On waking a repeater, the radio synchronises itself with the repeater, completes the transmission and makes the new site its home site.

transmission and makes the new site its home site.
Ø 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.
Ø Active Site Search does not necessarily find the best site, but rather allows the radio to move to the next “in range” site.
