24E1 SDH Multiservice Access Platform
型号：LNK-MSAP155-24
►Two STM-1 optical interfaces with 1+1 redundancy;
►Integration of SDH, PCM, PDH and Ethernet.;
►Provide up to 4 Ethernet networks with physical isolation;
►Provide 6 slots, can insert 8E1 card, 8 FXO/FXS card, 8 RS232/RS485/RS422 card., Ethernet card, E&M, Magnet, Hotline etc.
Overview
LNK-MSAP155-24 SDH/MSAP Multiplexer is a newly-developed optical fiber transmission equipment by E-link based on SDH technology. LNK-MSAP155-24 SDH MUX manages to satisfy not only users needs, and other fiber optical transmission/access services, but also users needs for and more reliable . LNK-MSAP155-24 SDH optical multiplexer can be directly connected to the remote PDH multiplexer, optical modem and multi-service multiplexer and so on, LNK-MSAP155-24 fits a variety of environment . LNK-MSAP155-24 STM-1grade SDH multiplexer can be used as a small MSAP equipment which integrates multiservice access, SDH transmission and PDH optical access functions. It also provides succinct and faultless which would carry out equipment configuration, data collecting and real-time monitoring on network performance.
Features
►Two STM-1 optical interfaces with 1+1 redundancy.(Either one fails, the other will back it up).
►Two V.35/V.11 [N×64K (N = 0 ~ 31)] channels.
►Integration of SDH, PCM, PDH and Ethernet.
►Provide up to 4 Ethernet networks with physical isolation, to achieve N×2.048Mbps bandwidth.
►Provide 6 slots, can insert 8E1 card, 8 FXO/FXS card, 8 RS232/RS485/RS422 card., Ethernet card, E&M, Magnet, Hotline etc.
►Modular configuration and is upgradeable.
►Support point-to-point, chain-shaped and ring network.
►Compliance with the ITU-T G.813 standards and fully meet the timing accuracy.
►Faultless feature, online real-time monitoring.
►Standard 19-inch 1U chassis structure, easy to install.
