Chapter 2. Eclipse Edge System Description
IDUspe Ethernet Module
The Ethernet module in the IDUspe 16x incorporates an intelligent layer 2 (L2)
switch, to provide the switching, prioritization and queuing functions between ports
P1 and P2, and transport channel C1. It supports address learning for efficient
management of Ethernet traffic in multi-host situations, and advanced settings for
traffic prioritization.
The MAC address register supports 1024 entries.
Inter-frame gap (IFG) and preamble stripping is used; the frame IFG (12 bytes) and
preamble (8 bytes) are stripped at the Tx end of the link and re-inserted at the far end.
It’s benefit is most noticeable with small frame sizes where the IFG and preamble
represents a more significant part of the total frame size.
The two 10/100Base-T Fast Ethernet ports are connected to the transport channel in
transparent or VLAN operational modes. Channel capacity is incremented in 2 Mbps
(2.048 Mbps) steps.
Refer to:
• Typical Throughputs on page 11
Orange flashing Configuration not supported or software/
hardware incompatible, or diagnostic mode
selected, such as tributary loopbacks.
Red Critical alarm (traffic affecting)
7 NMS 10/
100Base-T
Two RJ-45 ports for Portal and/or ProVision network
management access. Ports are also used to provide NMS
connectivity to co-located Aviat or third party radios.
The green connection-status LED is on for a valid Ethernet
connection. Off indicates no connection or an invalid
connection.
The orange activity LED flashes to indicate Ethernet traffic on
the port. The LED does not flash (is solid on) when there is no
traffic activity. (Activity LED is off when the connection status
LED is off).
Ethernet 10/
100Base-T
Two RJ-45 ports for Ethernet traffic connection.
Port connection-status and activity LED indications are the
same as the NMS port.
8 & 9 E1 tribs 1-8 and
9 -16
RJ-45 connector assemblies for tributary connections; one
RJ-45 port per E1. E1 termination is set for unbalanced or
balanced in Portal. Cable options provide extensions to BNC
connectors for unbalanced, or to RJ-45 plugs or unterminated
wires for balanced.
