RTAG – Remote TAP & Aggregation Gateway
The Remote TAP & Aggregation Gateway, RTAG, is a multi-purposed TAP and or Aggregator. Its ruggedized form factor is well suited for installation locations remote of data recorders. As an extension of the MITR, RTAG shares most of the design, logic and firmware with the MITR’s TAP Interface Module (TIM).
The RTAG provides multiple TAPs for optical or copper links and is available in several configurations: A 1-5G Optical (Ethernet & Fibre Channel) with 8 channels of Tx/Rx TAP’s & 8 channels Tx outputs, a 1G Copper Fibre Channel with 4 channels Tx/Rx TAP’s & 4 optical channels Tx outputs and a 1-10G Optical (Ethernet & Fibre Channel) with 8 channels Tx/Rx TAP’s & 8 channel Tx outputs.

RTAG contains the ability to store up to (8) configurations that are selectable with either CLI commands or the (3) discrete input lines. RTAG can increase the number of data streams per transmit channel with programmable aggregation. The receive side of each TAP’s can either be passed-thru one-to-one to the transmit outputs, can be aggregated from multiple TAP’s to one or more transmit outputs (as programmed by the user) or filtered before the transmit outputs and PCM encoding. The figures below detail the RTAG in “breakout/monitor” and “aggregation” modes.
