IMUX 2000 8-Port DACS
Brand: RFL Electronics
Catalog ID: IMUX_2000
The IMUX 2000 8-Port T1/E1 DACS, provides full cross-connect capability as well as a reliable level of system restoration. The RFL DACS enables the termination of up to eight [8] T1/E1 ports in a common platform while also providing full DS0 Time Slot Interchange capability. Redundant DACS modules are available for critical applications, which cannot tolerate single point of failure network architectures. Communications interface options for the DACS include built in T1 CSU, or fiber optic interface adapters, using Code Mark Inversion (CMI) encoding technology. In the event the application is time sensitive in nature the RFL DACS can be confi gured as an Intelligent Line Switch (ILS) in order to provide ultra high speed path switching. System restoration is accomplished through the use of alternate DS0, Time Slot Interchanged maps. The alternate maps are predetermined and pre-programmed through our user friendly Network Management Software. An alternate DS0 map is invoked automatically upon detection of T1/E1 failures (e.g. AIS, Loss of Frame, excessive BER). The time necessary to switch to an alternate map, upon detection of failure, is programmable down to 1 millisecond.
