Rule 36-101-6.3 - Procedure1. Any agency or private sector emergency response organization desiring to operate on MSWIN or having access to Special Event talk groups, will, through an authorized representative, execute the Mississippi Interoperability Channel Plan (MICP) Memorandum of Understanding prior to the issuance of system identification numbers. 2. The MSWIN network manager will be notified prior to the use of the state-wide special event talk groups. In the event of an emergency the network manager will be notified as soon as possible. 3. Depending on the event regional MSWIN special event talk groups should be utilized prior to state-wide MSWIN special event talk groups. 4. Temporarily Established Patches A. No prior approval is required for MSWIN member agencies establishing temporary patches to their own talk groups. B. The MSWIN network manager will be notified of any temporary patch in place for more than twelve hours. C. The patch must function in a technically and operationally consistent manner. a. The release time between messages should be less than 4 seconds. b. The audio quality should be a close representation of the original audio as heard on a typical subscriber radio. c. The audio shall be free of hum, clicks, or other extraneous noise. d. There shall be no clipping of the first syllables or loss of audio through the patch. D. The agency will continuously monitor and respond to calls on the patch. E. Although necessary, patches have the ability to degrade the performance of the MSWIN system, as such; agencies are requested to disconnect temporary patches as soon as possible. 5. Permanent Patches A. The MSWIN network manager must approve permanent patches prior to implementation. The possible impact on the MSWIN Grade of Service (GOS) and other users will be considered prior to the approval. B. Permanent patches are to remain active at all times on the talk groups specified within the MOU. This requirement is to provide the users with a consistent and functioning communications path. C. When utilizing external patching devices or bridging equipment such as an ACR 1000, only one talk patch will be programmed into a permanently patched MSWIN interface radio. D. The patch must function in a technically and operationally and consistent manner. Guidelines in section 4A - 4C.d are applicable for permanent patches. 6. Network Patch Communications Request A. When an agency needs to perform a temporary/permanent patch lasting more than twelve hours to MSWIN, requiring no MSWIN assistance, the agency must provide the MSWIN manager the following: * Agency requesting network patch.
* Contact information for the requesting agency.
* Reason for request/event type description.
* Details of the patch including the types of systems. Frequencies, or talk groups.
* All involved agencies requiring interoperability.
* Expected duration of event.
* Bridging equipment physical locations.
B. Agency to MSWIN requiring MSWIN assistance a. Agencies may request use of the technical resources from MSWIN by providing the information as required in Section 6A. C. The National Incident Management System (NFMS) procedures should be followed by the Incident Commander and MSWIN personnel. a. Avoid using an agency's primary dispatch channel. b. Require participating agencies to check in at the command post and provide portable radios and frequency/talk group channels for use during the incident to the Communication Unit Leader (COML). c. Assign radio call sign/designator information to connected agencies. d. Instruct MSWIN on where to setup and operate the tactical equipment if assigned. e. Inform MSWIN personnel which agencies are participating. f. Provide MSWIN with agency provided radios and an Incident Command Structure (ICS). g.
