These fiber optic and G.SHDSL modular or fix equipment carry Ethernet and E1/T1 in point to point line extension. Fiber Optical Multiplexers provides Gigabit Ethernet and multiple E1/T1 backhaul for 2G/3G/3.5G mobile networks over redundant fiber optics. Copper ranges include E1 and T1 CSU/DSU devices to convert data at edge of E1/T1 networks. G.SHDSL/Bis modems over 1 to 8 copper pairs transmit beyond 10km multiple interfaces. All are available as standalone and rack card for chassis. They are locally or remotely manageable by Telnet/SSH/SNMP or NMS. All are used in Telco infrastructure as well as private network access for campus and office buildings.
