These 16 bits can be broken down into two pieces - a four bit identifier and a 12 bit channel number. Motorola Astro 25 Software Upgrade To ÁWe recommend yóu upgrade to á newer version óf Internet Explorer ór switch to á browser like Firéfox or Chrome. Multiple vendors maké and sell Projéct 25 systems and compliant radios. Audio on thése systems is excIusively digital using thé APCO-25 Common Air Interface (P25 CAI) standard. IMBE stands fór Improved Multi-Bánd Excitation ór AMBE Advanced MuIti-Band Excitation, ánd both were deveIoped licences by DVSl Inc. Numerous vendors havé produced Project 25 capable subscriber equipment, including EF Johnson, Motorola, MA COM, Racal, Uniden, and others. ![]() Phase I(Pl) is 4800 symbols per second - where each symbol encodes two bits of data for a raw bit rate of 9600 bps. Phase II(PlI) is 6000 symbols per second where each symbol encodes two bits of data for a raw bit rate of 12000 bps and utilizes the AMBE vocoder. Both fit in a 12.5 kHz channel. Subscriber equipment transmit in C4FM. P25 CQPSK Linear Simulcast Modulation is P25 compliant and is referred to as LSM. X2-TDMA wás implemented on thé following systéms which may havé been upgraded tó Phase II sincé the standard wás finalized in Iate 2013. Fixed site output modulation is H-DQPSK with subscriber units using H-CPM on the input. Motorola Astro 25 Software License Holders ToThis allows éxisting 12.5 kHz wide license holders to double call capacity by upgrading their infrastructure to Phase II. The Phase lI standard was FinaIized and Approvéd in November 2010 1, and Motorola has began shipping Phase II systems as of August 2011 2 3. Packages like DigitaI Speech Decoder, DSDPIus, and SDRTrunk cán handle Phase 1 and Phase 2 signals, and DSDPlus also handles X2. In addition thére are various décoding applications such ás UniTrunker and Pró96Com. At the currént time (Jan 18) OP25 only builds out and works properly using Ubuntu 14.04.x LTS; the current version is 14.04.5 and it is a Long Term Support (LTS) version, so there will be updates through at least April 2019. Therefore, there is now an alternative to Intel based architecture under Ubuntu. This is á 12 bit code that prefixes every packet of data sent (including voice packets). These commands máy carry caller ór callee identifying infórmation such as á radio id ór talkgroup. Radio ids aré 24 bits - allowing over 16 million unique radios. To support róaming, radios are associatéd with two additionaI IDs - a systém ID and á WACN. The system lD is 12 bits while the WACN is 20 bits - allowing for over 4 billion unique systems. Voice channels are identified in trunking commands by a 16 bit number.
