Ethernet
to E3 Converter
(Ethernet over E3 Converter)
|
Description
Comarra
offers its Ethernet to E3 converters (Ethernet over E3 Converters) packaged
in a 19-inch rack-mountable chassis.
Comarra Ethernet to E3 converters (Ethernet
over E3 Converters) provides a 100BaseT data interface on the user side
which may be used to transport Ethernet traffic over a E3 link. The
converter provides a simple and cost effective method to convert and
transport 100BaseT Ethernet data over a E3 link.
Features & Highlights
- G.703 E3 34 Mbps to Ethernet interface
converter.
- 100BaseT full duplex fast Ethernet in
accordance with IEEE802.34, RJ-45.
- Provides framed and un-framed E3 option
- Stratum 3 Clock
- Local &Remote ac
- cess and monitoring with either RS232 or 10/100BaseT for remote
management over TCP-IP network
- Power Supply: -48 VDC or AC power supply
options available.
Applications
- 100 BaseT Ethernet to E3 Conversion
(100BaseT over a E3 interface).
