Overview
Specimen Track Gigabit SDH Ethernet Converter, 63 x VC12, Dual Uplink is a new, enhanced SDH or MSTP device. It is a carrier-class, high-compact platform and aimed for metro and SDH networks access. It can work as an Add-Drop Multiplexer (ADM), Termination Multiplexer (TM), and Gigabit Ethernet to SDH converter. It’s extremely strong cross-connection ability supports 64 K up to low or high order of SDH cross-connection. Not only can the STM-1 or STM-4 optical port work as the network uplink, but it can also configure the n x E1 ports as the network uplink simultaneously. The co-working optic and E1 network uplinks provide the customer with a very flexible networking configuration. Any combination of AC, DC dual power is supported and equipped on a rack-mountable casing. Such powerful cross-connect switches, flexible networking, link protection and redundancy power supply, various voice or data services make it the most function-rich, reliable and cost-effective solution for seamless migration of the E1 TDM network onto the SDH network.
