SDU/EFB/MP: Signal Distributor Unit for E1 / T1 Telecom Signals



The SDU/EFB signal distributor unit is a signal diplexer that allows to connect up to 24 devices to one E1/T1 sync output. This is a very compact and cost effective way to increase the number of E1/T1 ports available for synchronizing telecom switches and multiplexer as well as other devices that require a 1.544 or 2.048 MBit/s reference.
