ICT 4E1-10/100BT is an inverse multiplexer transmitting one Ethernet channel over multiple E1 links, bundling up to 4E1 (max.7.68Mbps full-duplex) . It allows bridge and routers to operate at their fastest rates. It also provides high speed access to SDH/SONET backbones where the only access services available are E1 lines.
ICT 4E1-10/100BT has a 10/100 Ethernet bridge with VLAN support for LAN-to-LAN applications over four E1 links. If one of the E1 links fails, the channel is still on, but at a reduced speed (automatic rate fallback) . It provides immediate connection upon installation and easy maintenance
FEATURES:
Ø Low-cost Ethernet extension and converter
Ø Transparent transport of LAN (10M/100M interface) traffic over 1-4 unframed E1 links
Ø Full compliance with IEEE 802.3 and MII interface standard
Ø Network Interface: 10 Base-T/100 Base-T, half/full duplex mode
Ø Transparent transport of super long frame per IEEE 802.1Q
Ø Data rates from 1.920Mbps to 7.680Mbps with automatic fallback and VLAN support
Ø Built-in dynamic MAC address LAN table (1024) , filtering function of local data frame
Ø LAN data frame FCS checking with alarm, built-in SDRAM controller
Ø Selectable buffer size for different application needs
Ø High jitter tolerance level of up to 512UI for added reliability
Ø Comprehensive alarm indicators
Ø Compliance with ITU-T G.703, G.704, G.823, timeslot assignment not supported
Ø Supports both HDB3/NRZ coding
Ø Built-in BERT and loopback test function for 1-4 E1 links with automatic rate fallback
Ø Remote terminal reset from local terminal
Ø 220VAC or -48VDC power supply
