Minimum requirementsIn order to accommodate subscriber units with a limited talkgroup capacity,the SIEC has identified the following talkgroups as a minimum requirement forall LWIN subscriber units with the capacity for less than 200 talkgroups perradio.DESIGNATOR*INTEROP-1*INTEROP-2*INTEROP-3*INTEROP-4*INTEROP-5*INTEROP-6*INTEROP-7*INTEROP-8*INTEROP-9*R(region number)-COORDCALL*R(region number)-COORDTK-1*R(region number)-COORDTK-2*(PARISH)-1*(PARISH)-2*(PARISH)-3*(PARISH)-43USELOCAL/STATE AGENCY INTEROPERABILITYLOCAL/STATE AGENCY INTEROPERABILITYLOCAL/STATE AGENCY INTEROPERABILITYLOCAL/STATE AGENCY INTEROPERABILITYLOCAL/STATE AGENCY INTEROPERABILITYLOCAL/STATE AGENCY INTEROPERABILITYLOCAL/STATE AGENCY INTEROPERABILITYLOCAL/STATE AGENCY INTEROPERABILITYLOCAL/STATE AGENCY INTEROPERABILITYREGION (region number) CALLINGREGION (region number) INTEROPERABILITY TALKREGION (region number) INTEROPERABILITY TALKDEDICATED (PARISH) INTEROPERABILITYDEDICATED (PARISH) INTEROPERABILITYDEDICATED (PARISH) INTEROPERABILITYDEDICATED (PARISH) INTEROPERABILITY

The ten mutual aid conventional channels detailed in section F of this policymust be programmed in every mobile and portable radio.C. Statewide Band UseThe SIEC has designated that all first responder interoperablecommunications occurring in Regions where equipment exists will utilize thestatewide LWIN system.The LWIN system talkgroups will be programmed by denoting an asterisk (*)followed by the talkgroup identifier. In verbal communications, this asterisk isreferred to using the word “STAR” (i.e. “switch to STAR R1-COORDCALL).When the word “STAR” is heard, this means the LWIN system.D. Interoperability Calling TalkgroupsAll subscriber units operating on the LWIN system will be programmed withdesignated interoperability calling talkgroups as listed above in Section II. TheSIEC has designated the “calling” talkgroup for each Region as COORDCALL.It is recommended that the appropriate calling talkgroup be continuouslymonitored by all first responder agency dispatch centers operating on theLWIN system. First responder agencies requesting mutual aid assistancefrom other agency first responders may utilize the calling talkgroup to makeinitial contact with the assisting agency. Once the assisting agency(s) havebeen contacted, the dispatcher or incident commander as appropriate willassign an interoperability talkgroup(s) and/or channel(s).4

Interoperability TalkgroupsAll subscriber units operating on the LWIN system will be programmed withdesignated statewide interoperability channels and talkgroups. The SIEC hasdesignated that during emergency events, whether local, regional orstatewide, the incident commander will determine talkgroup/channelassignments and that these assignments will take precedence over otherassignments for non emergency events.The requesting agency upon making contact with the assisting agency(s) willthen direct their radio traffic to either COORDTK-1 or COORDTK-2 within theirregion as designated by the incident commander. In the event thatCOORDTK-1 or COORDTK-2 is being utilized, the requesting agency canutilize any of the four parish talkgroups or ten INTEROP talkgroups that arenot being utilized.1) Local Talkgroups:All subscriber units operating on the LWIN system will be programmed withfour designated talkgroups for the parish in which the first responder agencyresides. In addition, the subscriber units are programmed with the four parishtalkgroups for each of the parishes within their designated region. The parishtalkgroups are available to first responder agencies for day-to-day andemergency operations requiring multi-agency communications within theparish; in addition to use for localized events in which agencies outside of theirparish provide assistance. Parishes are encouraged to develop their owninternal standard operating procedures use of the parish talkgroups.5

2) Regional Talkgroups:All subscriber units operating on the LWIN system will be programmed witheach of the nine Regional COORDCALL and COORDTK-1 and COORDTK-2talkgroups. For Law Enforcement Agencies only, the subscriber units areprogrammed with each of the nine Regional BOLO and Tactical Channels.While the Regional COORDCALL is a calling channel, in which requestingagencies can call other first responder agencies monitoring the callingchannel, the COORDTK groups are designated for regional day-to-day andemergency operations that require multi-agency, multi-jurisdictional and multiparishresponse.The incident commander will make the determination on whether to utilize thefour designated parish talkgroups in which the incident is occurring or theregional COORDTK groups for that region based on the size, participants andcommunication requirements of the incident.For large scale events, the incident commander is encouraged to utilize ICSForm 205 (Appendix J), Incident Radio Communications Plan, to assist in theassignment and use of talkgroups.3) Statewide TalkgroupsAll subscriber units operating on the LWIN system will be programmed withfour STATE talkgroups. These four talkgroups are designated for Stateagency to State agency use only. State agencies will utilize the RegionalCOORDCALL talkgroups to call another state agency for assistance.For multi-state agency response the incident commander will designate theuse of the STATE talkgroups. For large scale events, the incident commanderis encouraged to utilize ICS Form 205 (Appendix J), Incident RadioCommunications Plan, to assist in the assignment and use of talkgroups.Example: GOHSEP EOC requests assistance from Troop L,GOHSEP EOC would call Troop L on *R9-COORDCALL andthen the GOHSEP EOC Incident Commander would direct themto an appropriate STATE talkgroup4) Interoperable TalkgroupsAll subscriber units operating on the LWIN system will be programmed withten INTEROP talkgroups. These talkgroups are available to both local andstate6

agency first responders in the event additional talkgroups are required at thelocal, regional and/or state level. Due to the potential for multiple events goingon at once, incident commanders are encouraged not to use more than threeof the INTEROP talkgroups during an event.5) Monitoring of Talkgroups/EavesdroppingAll local, regional, state and interoperable talkgroups are designated for eitherday-to-day or emergency operations. First responder agencies that are notdirectly involved in an event or incident should not monitor (eavesdrop) onthose talkgroups, due to the potential to tie up multiple repeaters and addunnecessary congestion on the statewide system, resulting in busy radiosignals. As such, these interoperable talkgroups are to only be utilized for firstresponder agencies directly involved with the response.7
