DESCRIPTION
Litech WB7 DSX Balun Panel is Modular design, it is capable of high density installation. Each circuit in the DSX-SMT1/E1 panel is independence for choose the capacity as needed to reduce the initial set-up cost, and for easy maintenance the independent circuit module can be replaced separately. This panel in 23” rack consists of 32 circuits modules in the chassis (Maximum: 64 circuits).
Single-circuit removable DSX-SME1 Jacks allow jack maintenance without disrupting other circuits or requiring any I/O cabling changes.
Litech WB7 DSX Balun Panel is a centralized termination point for digital equipment at DS1 (1.544Mbps) and E1 (2.048Mbps) digital signal bit rate. It provides SDH(Synchronous Digital Hierarchy)networks STM-N(N=1/4/16) terminal equipments, the circuit jumping, cross-connecting, monitoring & testing access functions for the above digital signal bit rate.
