TMR 32x8 DDCS

32x8 Double Digital Cross Connect System

Provides blocking cross connection up to 992 of 64Kbit/s channels in form of 32 E1 in pairs using up to 248 of 64Kbit/s channels in form of 8 E1 in pairs

Product Overview

  • Offers blocked full cross connect functionality to cross connect between the double of 32 inports and 8 outports.
  • Aggregate DS-0s, \"n\"x64Kbps consecutive data channels and fractional E1 channels to full E1 channels
  • E1 Monitoring interface monitors an E1 signal through a Hi-Z path, without in any way disturbing the live E1 traffic that is required to be monitored.
  • Both receive and transmit directions of E1 can be monitored simultaneously in pairs.
  • Combine traffic from partially utilized facilities onto a single fully utilized E1.
  • Remote access through Ethernet for management and configuration
  • Occupies only a 3U high rack space, and is complete 19-inch stand alone unit that provides connectivity for up to double of 32 in and 8 out E1.
  • The unit operates an a -48Vdc input power supply (AC input adapter is optional for AC mains operations)
