Product Description
The functional version of the IFX2 is SL91.
Application
IFX2 boards form XPIC workgroups to expand the capacity of an Integrated IP microwave hop (native E1+Ethernet) when transmitting native E1 services, native Ethernet services, native MPLS/PWE3 services, or a combination of these services.
Figure 1 Application scenario of IFX2 boards
NOTE:
In the preceding figure, if transmitted over Integrated IP microwave, E1 services can be native E1 services or CES/ATM E1 services, and Ethernet services can be native Ethernet services or ETH PWE3 services.
Service boards shown in the preceding figure can be Ethernet interface boards, E1 interface boards, or Smart E1 processing boards.
Functions and Features
The IFX2 receives and transmits one channel of IF signal, and provides a management channel and -48 V power supply to the ODU. In addition, it supports cross-polarization interference cancellation (XPIC) processing for IF signals.
Table 1 lists the functions and features that the IFX2 supports.
Table 1 Functions and features that the IFX2 supports
