[AusNOG] ISDN acting the maggot

[Christopher Mclean]

Add to this you are alone to make all the connections but as soon as you are ready to plug in and test the CEO, General Manager, CFO all who you have not seen for 3 months will choose that time to come and watch. It will be the only one to fail!

No matter how many times you've checked and double checked the RX/TX lines of a device or service, or have worked with it in the past, it's wrong! :)

I learnt recently that it's been dubbed "UART dyslexia" by the internet at large. What's worse is it usually only becomes apparent after you've soldered, or crimped the pairs...

RX/TX pairs not correct.  I blame Friday.

Hi folks,

CE question but hopefully someone has an idea amidst the hail of "take it to SAGE".  What would cause an ISDN connection to be able to be looped back fine both ends (so a loopback on the provider end is visible and get CD *AND* a loopback on customer end shows at provider the same) but if the connection is provider to customer there's no carrier?
