A channel routing manager that is employed by a mobile telecommunications switching office routes voice and data calls over a carrier facility interconnecting a cell site transceiver to the mobile cellular switch and includes first and second channels that utilizes first and second encoding methods, respectively. The channel routing manager comprises a hunt group mechanism including first and second channels, wherein the first channels are sorted together and the second channels are sorted together. In addition, the channel routing manager comprises a control mechanism for routing the voice calls to one of the first channels unless all of the first channels are busy and then routing the voice calls to one of the second channels, and for routing the data calls to one of the second channels unless all of the second channels are busy and then routing the data calls to one of the first channels. In a first embodiment of the hunt group mechanism, the hunt group mechanism comprises a dual-fixed order hunt group with the first channels at a first end beginning with a lowest channel number and the second channels at a second end beginning with a highest channel number, whereby voice calls are routed to the lowest available channel and data calls are routed to the highest available channel. In a second embodiment, the hunt group mechanism comprises opposing first and second fixed order hunt groups, wherein the first fixed order hunt group begins with the first channels and ends with the second channel, and the second fixed order group begins with the second channel and ends with the first channels. In the second embodiment, the voice calls are routed to the first fixed order group and the data calls are routed to the second fixed order hunt group. In a preferred embodiment, the first channels utilize voice compression schemes and the second channels utilize uncompressed encoding schemes.
