Why MTRBi FCC (In US only) requires manufacturers to offer only devices that operate within 12.5kHz VHF and UHF channels by 2011. By the year 2013, all VHF and UHF users are required to operate in 12.5kHz channels. While there is no current mandate requiring a move to 6.25kHz, such discussions are on-going at the FCC & other agencies. It’s only a matter of time before the ability to carry two voice paths in a single 12.5kHz channel, also known as 6.25kHz equivalent efficiency, becomes a requirement in VHF & and UHF bands. Presently, FCC rules are in place to mandate manufacturers to build radios capable of the 6.25kHz efficiency for VHF and UHF bands, but the enforcement of these rules are put on hold. In the meantime, MOTOTRBO™ offers a way to divide a 12.5kHz channel into two independent time slots, thus achieving 6.25kHz-equivalent efficiency today. MTRBi

Telex Radio Dispatch MTRBi interface supports: Conventional Direct Mode and Capacity Plus modes Does not support IP Site Connect Mode at this time. The MOTOTRBO™ system can be configured to operate in analog or digital. When operating in analog mode, MOTOTRBO™ supports one voice path (transmit and receive) on one physical channel, and can be configured to operate in 25kHz channel bandwidth systems and/or 12.5kHz channel bandwidth systems. When operating in digital mode, MOTOTRBO™ uses one physical channel configured for a 12.5kHz channel bandwidth. On that one direct 12.5kHz physical channel bandwidth, a MOTOTRBO™ digital system can support only one voice (or data) path at a time if communication is direct without a repeater. Digital through a repeater the system uses TDMA and can support two voice or data channels or one of each. MTRBi

8. 8 Bosch Communications Systems Confidential | ST/MKP-AM-Lio | 10/29/2010 | © 2010 Robert Bosch LLC and affiliates. All rights reserved. Basic System Topologies Capacity Plus Capacity Plus mode, MOTOTRBO™ trunks the logical channels of multiple repeaters (operating in digital repeater mode) at the same location. This allows the radios to share the logical channels, resulting in less waiting time to access the system and increased channel capacity for quality of service. The probability of all channels being busy at the same instant is low, therefore the probability of a call being blocked is lower than when only one channel can be accessed. Capacity Plus is a single site trunking configuration of the MOTOTRBO™ system. In a Capacity Plus system, all the “idle” radios (i.e. radios neither receiving nor transmitting) are on an idle channel called the Rest channel. Therefore, a new call always starts on the Rest channel. At the start of a call, the Rest channel repeater selects one of the idle channels as the new Rest channel, informs the radios on the current Rest channel about the new Rest channel is, converts the current Rest channel to a traffic channel, and starts repeating the bursts sent by the radio.
