SDH

ONC-SDH155 is an upgrade SDH / MSTP multiplexer. SDH / MSTP (Multiple services transmission platform) multiplexer use the new technology integrated components, single board structure. The price is approach to the PDH. It transmits the data/signal via optical fiber which can reduce the material of 2M cable and DDF (digital distribution frame) and reduce the occupying room. It’s 19 inch rack which can insert different interface cards. Supply AC/DC. Feartures: 1. Standard 19-inch 1U chassis structure, easy to install. 2. 155M, 622M two STM-1 optical interfaces with 1+1 channel protection.(Either one fails, the other will back it up) 3. Support V.24, V.35, RS422 and other data transmission. 4. Integration of SDH, PCM, PDH and Ethernet. 5. Provide up to 4 Ethernet networks with physical isolation. 6. Provide up to 24 channels telephone and 63 channels E1 slips. 7. Support networking mode: point to point, chain type, tree type, star type, ring type etc 8. In compliance with the ITU-T G.813 standards. 9. Faultless network management feature, online real-time monitoring.
