Multiplexer E1-XL
(rack-mount model 1U)


Multiplexer E1-XL Features:
  • Two E1 Interfaces
  • Integrating multiplexer mode with 2 data ports and E1 sub-link
  • ITU G.703, G.704, G.706 and G.823 compliant
  • Up to 2 km
  • CAS and CRC4 framing
  • Two data interfaces: Ethernet or V.35/RS-530/RS-449/RS-232
  • Full duplex synchronous mode
  • Digital, remote and line loopbacks
  • Integrated BER tester
  • Supervisory RS-232 port
  • SNMP Ethernet 10Base-T control port
  • Remote management

  • 1U high rack-mount enclosure for 19 inch cabinet
  • AC or DC power
  • Certificate N OS-2-SP-1638

The E1-XL is a integrating multiplexor for Fractional E1 services. It can split the E1 link into several digital channels. Data from two digital interfaces with rates from 64 kbit/sec to 1984 kbit/sec are placed into specified timeslots of main E1 link. Other timeslots are passed into secondary E1 link.

The device is provided as a stand-alone unit, as a rack-mount 19'' 1U case, or as a card for 19'' 3U Cronyx rack.

For the rack-mount 1U unit, there is a choice of Ethernet, V.35 or multi-standard digital interfaces. The multi-standard interface is switchable by adapter cable to RS-232, RS-530, RS-449 or V.35 standards. The V.35 interface is ended with the standard M34 female connector.

The E1-XL can be AC or DC powered.

The device setup and diagnostics are performed via the RS-232 supervisory port.

Currently available models are listed in Prices. Please, contact technical support if you are unsure which model to choose.
