IDU GE 20x
IDU GE 20x supports Gigabit Ethernet plus up to 20xE1 waysides.
Depending on the required Ethernet throughput, channel bandwidths ranges from 7 to
56 MHz, with modulation options from QPSK to 256 QAM. Maximum Ethernet
throughput is 360 Mbps using one or both transport channels.
Configured link capacity may be fully assigned to:
• Ethernet only.
• Between Ethernet and up to 20xE1 or 20xDS1 circuits in 1xE1 or 1xDS1 steps.
• E1 or DS1 circuits only, for link options of 5x, 10x, 16x, 20xE1, or 16xDS1.
Ethernet capacity is licensed; NxE1/DS1 capacity is not.
It includes a Layer 2 switch to support two customer 10/100/1000base-T electrical
ports, and an optional SFP port for either 1000Base-X optical or 1000Base-T electrical
connections. These interface to one or two transport channels using transparent, VLAN
or mixed operational modes.
The switch incorporates:
• Programmable switching fabric: transparent mode, VLAN (secure) mode, or mixed
mode.
• Comprehensive QoS policing and prioritization options (802.1p).
• VLAN tagging (802.1Q and 802.1Q-in-Q).
• RWPR
• Layer 2 link aggregation (802.3ad).
• Flow control through 802.3x pause-frame option.
• Jumbo frames to 9600 bytes.
