The ŁC-480D1 Digital Switchboard is the basic The switchboard offers extensive diagnostic component of stationary and field integrated functions enabling to check the device’s status special communications systems, and it has and the parameters of the digital trunks been designed for use on both tactical and connected to it. The device has an embedded strategic levels of the chain of command. local agent of the management system. The device offers also a built-in DSTG module allowing to translate Storczyk/DSS1 signalling and to convert the CVSD/PCM coded speech (according to Stanag 4578). The ŁC-480D1 Digital Switchboard is used in building the telecommunications network of the Storczyk system. It may work as a transit node or, in cooperation with the KX-30M The ŁC-480D1 Digital Switchboard is used for multiplexers, as a high capacity terminating switching digital channels of rates ranging from node supporting telephone subscribers (analog 16 to 2048 kbps being the multiple of the 16 and digital), as well as ISDN and Storczyk data kbps speed. transmission terminals. The device can switch up to 21,120 of 16 kbps channels grouped into 28 trunks of Storczyk, E1, E2 or E3 types with their rates ranging from 128 to 32,768 kbps. The trunks have two interfaces: electric (Stanag 4210, G.703, Eurocom) and fibre optic. Transbit Sp. z o.o. ul.

The ŁC-480D1 Digital Switchboard can be managed locally through a hand-held terminal or remotely from the SZAŁ-99 management system. The SZAŁ-99 management system enables remote control over all switchboards of the system and of the KX-30M multiplexers connected to them as well as of subscribers’ devices. SZAŁ-99 is used for network planning and designing, configuring the work parameters of individual devices and for monitoring the network status. The ŁC-480D1 Digital Switchboard has its own highly stable frequency standard. The device can cooperate synchronically with a clock received from any trunk or with an external frequency source. The device has been qualified to the N7 group according to WPN 84, MIL-STD-810D.
