Process & Phases
A. Phase 1 – Mobile and Portable Transition – Touch 1
All mobile and portable radios, including RF modems, (hereafter referred to as “devices”) which are currently operating on any of the systems listed in Section I. A. are impacted and must be “touched” during this phase. At the completion of Phase 1, all devices will be programmed to operate using the existing channels (Pre-rebanding currently FCC Licensed Frequencies) and the new channels (Post-rebanding future FCC Licensed Frequencies).
The work to be performed to transition these devices depends upon several factors:
• Device type
• Device age
• Device memory capacity
EMR with the assistance of Motorola and EF Johnson evaluated the inventory of devices and classified each radio into the following categories:
• Retune – these devices are newer, have sufficient memory to store all the existing channels and the new channels and require the least amount of work. The new channels will be programmed into these devices using the Customer Programming Software/Radio Service Software.
• Flash Reprogram – these devices are older but are not so old that they need to be replaced. Software upgrades have been developed to allow these devices to operate with the new channels. The software upgrades will be installed in each device using a “flashkit”. The flashkit updates the operating software with the new frequencies and band plan. After the device has been “flashed” the new channels must be programmed into the device using the retune procedure
• To be Replaced – these devices are very old, can not have their operating software updated via a flashkit, and must be replaced by new devices.
• Loaner - A fourth category, “Loaner”, was required for a large percentage of the Department of Corrections (DOC) devices. The existing DOC devices have a three position toggle and a 16 position dial restricting the number of talkgroups/systems to 48 (3 x 16). To facilitate rebanding, these 48 talkgroups need to be duplicated for the new channels. Rather than replace these devices, Nextel provided “loaner” radios that are capable of storing and accessing more than the 96 talkgroups required for the transition to the new channels. Once the Fixed Network Equipment is transitioned to the new channels, the existing DOC devices will be returned to the DOC users with the new channels programmed and the loaner radios will be returned to Nextel.
• Vendor Change – Several agencies that had devices categorized as “To be Replaced” opted to change from their existing device vendor (Motorola or EF Johnson) to the other device vendor.
B. Phase 2 – Fixed Network Equipment Transition
When Phase 1 is completed all devices have been retuned, reprogrammed, or replaced and will operate using the existing channels (Pre-rebanding currently FCC Licensed Frequencies) and the new channels (Post-rebanding future FCC Licensed Frequencies).
The transition of the Fixed Network Equipment, Phase 2, will proceed as follows:
1. Perform pre-rebanding coverage tests.
2. Modify the 200+ FCC Licenses to add the new channels.
3. Reprogram the conventional mutual aid sites to the new channels.
4. Reprogram the IPSC Statewide Trunked and Data sites to the new channels.
5. Reprogram the DOC facilities to the new channels.
6. Perform post-rebanding coverage tests.
7. Modify the 200+ FCC Licenses to remove the old channels.
C. Phase 3 - Mobile and Portable Touch 2
After all fixed network equipment (Conventional Mutual Aid, IPSC Statewide Trunked and Data, and DOC Facilities) has been programmed to operate on the new channels a second “touch” of the mobile and portable devices must be performed. During Touch 2, the old channels will be removed from the devices.
