IFH2 Introduction (RTN 600 R3)

HUAWEI TECHNOLOGIES CO., LTD. Huawei Confidential

Function The IFH2 receives and transmits one IF signal, and provides the management channel to the ODU and the -48 V power that the ODU requires. The IFH2 supports the hybrid transmission of E1 services and Ethernet services.

Function :IF Processing

Supports the Hybrid microwave frame and supports the pure transmission of the E1 or Ethernet signals and the hybrid transmission of the E1 and Ethernet

signals. Supports the adaptive modulation (AM). Maps service signals into microwave frame signals. Codes and decodes microwave frame signals. Modulates and demodulates microwave frame signals. Modulates and demodulates ODU control signals. Combines and splits service signals, ODU control signals, and –48 V power supplies.


Function Function :Ethernet Service ProcessingThe front panel of the IFH2 has a GE electrical interface. The GE electrical interface supports the following port functions:Supports the setting and querying of the working modes of the Ethernet ports. The working modes supported are 10M full-duplex, 100M full-duplex,

1000M full-duplex, and auto-negotiation. Accesses Ethernet II and IEEE 802.3 service frames with a maximum frame length of 1966 bytes. Supports the port-based flow control function that complies with IEEE 802.3x. The GE electrical interface also supports the following Ethernet QoS functions:Supports the flow classification function that complies with IEEE 802.1p. Schedules the queues of four priority levels in the strict-priority (SP) mode.


Front Panel

There are indicators, an IF port, a GE port, an ODU

power switch, and labels on the front panel.


Indicator


Valid Slot In the IDU 620, the IFH2 can be installed in slots 5, 6, 7, and 8.
