Detailed Product Description
1. DSX SME1/T1 is a centralized termination point.
2. Easy maintenance.
3. High capacity.
4. Reduce initial set up cost.
The DSX-SME1/T1 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.
It is Modular design, it is capable of high desity 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. The panel in 19” wide rack consists of 64 circuits module in the sub chassis.
Single-circuit removable DSX-SME1 Jacks allow jack maintenance without disrupting other circuits or requiring any I/O cabling changes.
