Re: DSL Loses Sync when Phone is Used said by drainbamage:
The MTU is no longer used by the voice side testers for remote testing and is no longer being deployed in CA to the very best of my knowledge. Also, on the West Coast you are looking for what looks to be a small circuit board that looks like it was dipped in a bucket of black paint ( still anything inline with the red and green wires can go ).
Nope, not installed anymore. They are still useful during MLT testing if they are present when working on non-DSL POTS problems. HOWEVER, I frequently encounter MTU's that MLT for whatever reason didn't see. So one MLT run on the line is not proof that an MTU is not there. Most of them look like the ones in IdleDeamon's picture:) They can also be an unpainted, beige circuit board or in some cases they're encased is grey plastic and say "Keptel" on them. *For the record:* ONLY SBC personnel should be fooling around with these and the CLEC has nothing to with it and should not be touching it. That being said, it's also true that removing this little bugger is something we should be doing before we certify the circuit for service. Idle, IM me with your DSL# so we can get someone out there to get rid of that thing for you:) And Leonard, are you able to post a pic of your NID opened up?

Of course! PacBellTek -- Thanks for your help in all this! While looking again at the NID, I realized that I could pop the little tray card for my apartment (Unit C). I noticed a black box similar to the one you mentioned might be an MTU. Pictures of the whole affair are below. |

kudos:7 | PacBellTek, what is the difference between an MTU and a half-ringer? I see the terms used interchangeably and I know they are very similar in physical appearance and effects on the DSL circuit, but I didn't know the differences. Thanks. |
