I'm looking to use two PTP650/670 links through a common repeater site. These links will be running TDM traffic. However, no traffic needs to be dropped at the repeater site. Do I need any NIDU's at the repeater site, or can I just bridge the traffic between the the ODU's with an Ethernet cable? If I do need NIDU's at the repeater site, do I need two or can I do it with one? Again, no traffic is going to be dropped at the repeater site.
NIDU-->PIDU-->ODU 1 site A --------> ODU 2 repeater site ???? ODU 3 repeater site ---------> ODU 4 site B-->PIDU-->NIDU
