NI3030
Network Interface Modules |
The model NI3030E is a chassis-based module that interfaces headend,
hub or regional data center (RDC) WAN routers and switches to Aurora’s transport
network. It provides up to 16 full duplex, wirespeed, symmetric, dedicated, and
completely independent local 100Mbps connections to up to 16 customers, for a total
throughput of 3.2 Gbps.
The unit’s full duplex optical port accepts any of a variety of SFP
(plug-in) transceivers available from Aurora Networks for network communications
with Aurora’s high-speed digital transport system and DWDM optical transport
technology.
The NI3030E is a Layer 1 transport device and is fully transparent to
Layer 2 and higher protocols. Higher layer functionalities and external value added
applications such as VLAN tagging are preserved and passed through. Traffic is
channelized end-to-end via TDM, enabling a very high degree of security.
The NI3030E provides (1) 16 RJ-45 ports for connections to
Layer 2/Layer 3 WAN routers and switches, (2) a full duplex optical port, (3) a
standard Compact Flash card slot to store program and network configuration files,
(4) an RJ-45 10Base-T port for interfacing to a management server/terminal and
(5) an RS-232 craft port for connecting to a local terminal.
The NI3030E can provision new customer connections from the headend
in minutes, and can locally or remotely monitor and manage every active device in
Aurora’s fiber network via standard SNMP, including nodes, transceivers, and receivers.
The model NI3030N is available for network monitoring and node control
only, and does not include the 16 RJ-45 ports.
