E1-mux family

	E1-XL / B E1 drop-insert mux, for transmitting digital data over framed (G.704) E1 channels. Has two E1 channels and two digital ports. Flexible multiplexing scheme allows combining both digital data and voice traffic into a single E1 channel. Digital interface options include V.35, RS-530, RS232, X.21. There are also models with one or two Ethernet ports. Rack mount option (slot in 19'' 3U rack).
	E1-XL / K E1 drop-insert mux, for transmitting digital data over framed (G.704) E1 channels, rack mount 3U11. Has two E1 channels and digital port. Flexible multiplexing scheme allows combining both digital data and voice traffic into a single E1 channel. Digital interfaces - Ethernet or multistandard V.35/RS-232/RS-530/X.21/V.10/V.11.
	E1-XL / S E1 drop-insert mux, for transmitting digital data over framed (G.704) E1 channels, rack mount model 19'' 1U. Has two E1 channels and two digital ports. Flexible multiplexing scheme allows combining both digital data and voice traffic into a single E1 channel. Digital interfaces - Ethernet or multistandard V.35/RS-232/RS-530/X.21/V.10/V.11. Remote management via SNMP protocol.
	E1-XLC / B E1 mux with voice compression, for transmitting digital data over framed (G.704) E1 voice channels. Has two E1 channels and one digital port. Voice data from one E1 channel are compressed and directed to a second E1 port, the free space is used for data from digital port. Digital interface options include Ethernet, V.35, RS-530, RS232, X.21. Rack mount option (slot in 19'' 3U rack).
	E1-XLC / S E1 mux with voice compression, for transmitting digital data over framed (G.704) E1 voice channels. Has two E1 channels. Hve models with one or two digital port. Voice data from one E1 channel are compressed and directed to a second E1 port, the free space is used for data from digital port. Digital interface options include Ethernet, V.35, RS-530, RS232, X.21. Rack-mount 1U 19" (/S) or Rack mount card Cronyx 3U11 (/K)).
	E1-DXC / B Cross connector with 4 E1 ports. There are also models woth 3 E1 ports and one digital interface Ethernet, V.35, RS-530, RS-232, or multistandard interface V.35/RS-232/RS-530/X.21/V.10/V.11. Rack mount option (slot in 19'' 3U rack).
	E1-DXC / S Cross connector with 4 E1 ports. There are also models woth 3 E1 ports and one digital interface Ethernet or multistandard interface V.35/RS-232/RS-530/X.21/V.10/V.11. Remote management via SNMP protocol.

	FMUX-4-E2 Mux for transmitting 4 E1 channels over E2 channel. Also a model with 3 E1 channels and one digital port is available, with interface Ethernet. Rack mount enclosure 19'' 1U.
	FMUX-16-E3 Mux for transmitting 16 E1 channels over E3 channel. Remote management via SNMP protocol. Rack mount enclosure 19'' 1U.
	FMUX/SAT Variable frame structure multiplexor for transmitting up to 4 E1 channels over the synchronous link equipment with codirectional interface (e.g., satellite modem with V.35 DCE interface). Remote management via SNMP protocol. Rack mount enclosure 19'' 1U.

	E1-XL/S-IP Multiplexor E1-XL/S-IP it is intended for reliable transfer framed E1 (full or fractional) and unframed E1 over a asynchronous packet network (IP or Ethernet). Integration with LAN with bandwidth control and QoS support is provied. Optionaly E1 clock recovery over a network and voice compression is also available.
