Product Description

Overview:

SPC-MST is configured as a Terminal Multiplexer (TM) that integrates SDH and L2 switch fabric to combine TDM & Ethernet services in a STM1 link up to **5,**0 bps. It has 4 slots for service modules to support various combinations of traffic. With 2 aggregation optical STM*1 interfaces. SPC-MST can offer the service provider SNCP protection mechanism. It can be applied into different transmission methods. Its design of hot swap on optical card makes this product can correspondent to different transmission distances and application types.

SPC-MST has a centralized control architecture that limits the presence of processors and software to the main board. Tributary (plug-in) cards have no on-board processors and may be reused from one piece of equipment to another, or retrieved from stock without concern for software versions. SPC-MST  also offers local and remote software upgrade.

SPC-MST provides an easy to use and powerful EMS interface that allows the user to control the whole system at all times, it complies with the Telecommunication Management Network (TMN) concept giving it flexibility to connect to NMS systems.

Features:
