How to configure the Packet link with Radio Bonding ..?

1) The first four RL-IME is having this radio bonding feature2) Radio bonding is used if you have two links one with vertical & other with horizontal

frequency.

3) In XPIC Feature both H & V have the same frequency as you can see from the snap ,XPIC cableis used to eliminate the interference in both H &V link & doubles the capacity, but even if we

remove the XPIC Cable the transmission or packet data will through but it might carry

interference & errors in the data.

4) For 1+1 link the slot selection on AMM20p should be starting from even Slots link 2-3,4-5 & soon & for horizontal & vertical link together they should be either on the right side of the NPU

or on the left side of the NPU, in below case both links are on the right side of the NPU.

5) It is recommended that during packet assignment we should assign horizontal packet first &then vertical as normally horizontal link didnt carry traffic or E-1.

6) RL-IME 100 & RL-IME 101 should be used for the link for slots on the left side of the NPU,means from slot 2 to slot9 & RL-IME 102 & RL-IME 103 should be used for the link for slots onright side of the NPU, means from slot 12 up to 21.

7) On NPU3 B One RL-IME can configured up to 4 packet link & rest RL-IME with two packet links8) On NPU1 C, four RL-IMEs can be configured with four packet links.9) NPU3 B provides five RL-IMEs and NPU1 C provides 19 RL-IMEs.

Configurations for 1+1 protection can be in hot standby or working standby. In hot standby

mode, one transmitter is working while the other one, tuned to the same frequency, is instandby. It is not transmitting but ready to transmit if the active transmitter malfunctions.Both RAUs receive signals. When using two antennas, they can be placed for space diversity

with a mutual distance where the impact of fading is reduced.

In working standby mode, both radio paths are active in parallel using different frequencies,

realizing frequency diversity. Using two different frequencies improves availability, becausethe radio signals fade with little correlation to each other. Space diversity can beimplemented as for hot standby systems.

Ethernet traffic can be sent over a hop in the following ways:

Ethernet over packet link (Native Ethernet) Ethernet over PDH Ethernet over SDH
