[BC] Motorola PTP 400 Ethernet 'bridges'

[jeff@rfproof.com]

Greetings,

I am planning a four station urban RF STL system utilizing the Motorola PTP 400 (formerly Orthogon) 5.8GIG Ethernet bridge technology. The codecs will be APT Worldnet OSLOs. 

Who among us has experience with Ethernet bridge 'radios'? They will be used for all STL-TSL HD Radio link functions. Gary Liebisch and Tim Anderson caution 1 in a million packet loss is the the limit for UDP packet exchange from Exporter to Flexstar. However I understand TCP is coming to the HD Radio air chain.

In the application being planned, one link will carry all four stations to a central point about two blocks away from the studios. From there three links will be to the TX sites. Two sites are less than a mile, and the third (with two stations) is just shy of six miles. They are all line-of-sight.

The present STL system is T-1/Intraplex backed up by ISDN/Zephyr.
