The Crocus ADM 2P (Add and Drop Multiplexer with 2 modular Ports) is part of the universal Crocus access solution, and offers a flexible and modular approach for interface conversion and Time Division Multiplexing (TDM).
 
The unit is equipped with 2 fixed (F)E1 G.703 interfaces and 2 slots for user-selectable plug-in interfaces. The main application for the equipment is the use as as a dual port Nx64k multiplexer with (F)E1 G.703 output and an additional add-and-drop FE1 G.703 interface. This add-and-drop interface can be used for stacking the cards and creating a multiplexer with an arbitrary number of Nx64k input ports .

A complete range of user selectable plug-in interfaces makes the Crocus ADM 2P ideal for interfacing to almost any application.
 
Not only traditional serial interfaces such as V.35, V.36, RS-530, RS-232 and X.21, but also direct Ethernet 10Base-T connections with integrated bridge or IP router functionality are available.
