KIndly find the detail analysis about the ISU2 & IFU2 card:
1. IFU2- Supports Native E1+Eth integrated IP radio
ISU2- Supports Native E1+Eth and Native STM-1+Eth integrated IP radio
2. IFU2- L2 frame header compression:
a.Compresses the DA+SA+VLAN/MPLS+TYPE bytes in an Ethernet frame header.
b.Compression support: Common Ethernet frames without VLAN support 14-byte compression; a maximum of 22-byte compression.
c.Supports adaptive header compression. Automatically compresses VLAN tags and MPLS labels.
ISU2- L3 frame header compression:
a.Compresses the DA+SA+UDP bytes in an IP header.
b. Supports IPv4/IPv6 header compression transmission, which needs to be set on the NMS.
c.Supports adaptive header compression. Automatically compresses UDP headers.
3. Only newly introduced ISU2 can provide the packet header compression function, while IFU2 cannot.
As the headers of the above cards are not same, link could not be established in between.
