Multiplexer E1-XL
(stand-alone model)
 |
Features:
|
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 stand-alone unit, there is a choice of Ethernet, V.35 or multi-standard digital interfaces. The rack-mount card has the Ethernet and multi-standard interfaces only. 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 is performed by microswitches or via the RS-232 supervisory port. All diagnostics options are controlled from the front panel or the supervisory port.
Currently available models are listed in Prices. Please, contact technical support if you are unsure which model to choose.
