Only your site has connected
to the NRAO hub. |
This is normal if yours is the

One of the pictures will seem a little jerky: this is your own signal as
reprocessed by the hub, and will be replaced when the next site connects. |

output (pictures identical). |
Monitor 1 has a composite as well as an
S-Video output. Connect Monitor 2 to the Monitor 2

|
If persistent, ask your technical
contact to check the Error Count under the Diagnostics Menu. Your system may also be
checked by doing a local loopback under the Diagnostics Menu. If your picture does not freeze,
perform the same test at the Far system. Then perform a Far end loopback during a call:
if the picture freezes there are line errors. |
