The Digital Belt Pack (DBP) is one of RTS’ initial offerings in the wired digital party line solution space. The DBP provides TALK and LISTEN capability for up to four configurable audio conferences. In addition, the keys can be assigned for dedicated resources such as relay control. When operating as a digital party line device, the DBP connects to the OMNEO Main Station (OMS). The DBP can also be connected directly via OMNEO to any of RTS’ matrix products. This includes OMI cards in ADAM (or ADAM-M) frames or OMNEO ports on ODIN frames. When connected to an RTS matrix, the DBP acts as a wired, 4-button keypanel. The DBP automatically determines the correct mode of operation (digital party line connection to OMS or keypanel connection to the matrix) at power on. The DBP recovers power over an 802.3af or 802.3at compliant switch. One Ethernet port (PoE In) connects to PoE compliant power sourcing equipment. A second port (PoE Out) is available for daisy chain connections to other DBPs. The DBP comes in an over-molded enclosure which is IP-53 compliant. It has a full-color TFT display and an icon-based menu interface which allows for local configuration of key customer preferences.
