Ericsson ROJ208306/1 ET155-1-0 STM-1 (155 Mbit/s) exchange terminal transmission board for Ericsson SDH/AXE systems, terminating PDH tributaries onto SDH lines. Tech-Star (UK-based, shipped worldwide), enquire for stock.

The Ericsson ROJ208306/1 is an ET155-1-0 board, a 155 Mbit/s STM-1 exchange terminal card used within Ericsson’s SDH/AXE transmission equipment. The ET155 family terminates STM-1 optical or electrical transmission lines and can multiplex and demultiplex up to sixty-three 2 Mbit/s (E1) PDH tributary circuits onto a single 155 Mbit/s SDH line, acting as the interface between lower-speed PDH trunk traffic and the higher-capacity SDH transmission network. Physically, ET155 boards mount in a GEM magazine within Ericsson’s transmission and exchange racks, connecting to the group switch via a DL34 interface and controlled by an on-board regional processor. The ROJ208306/1 revision corresponds to the base ET155-1-0 variant of this family (a further revision, ROJ208306/2, is designated ET155-1-0-2). This card is typically sourced by network engineers maintaining or expanding legacy Ericsson AXE/SDH transmission infrastructure who need a matching interface board for spares or capacity growth.
