Faulty phone line


[link to this post]
 
My phone line died this morning, no dial tone even at master socket and engaged to callers Despite this my broadband is working at full normal speed. How can this happen? BT have diagnosed an external fault.

Hi,

It's possible one of the leg of the cable has broken/snapped off in the PCP or on the DP.
The broadband can continue to work on one of the leg.

ISP: PlusNet: Downstream rate = 79999 Kbps - Upstream rate = 19999 Kbps. Ping: 11ms.
Line Stats: Line attenuation Down: 7.8db Up: 8.7db

Insulation fault A-B will cause engaged tone. Usually indoors.

... and how would this explain the engaged tone callers to the number are getting ?

It kinda depends what sort of broadband you have ?

What is killing your dialling tone is a loop fault.

If you have FTTC then itís an exchange/E side/cab fault.

If itís ADSL then itís most likely an exchange fault before the DSLAM ties.

Not at full speed it can't. Not even half speed. It is severely degraded, and the fault can be anywhere including in the user premises before the modem.

My broadband basic info/help site - www.robertos.me.uk. Domains, site and mail hosting - Tsohost.
Connection - AAISP Home::1 80/20. 200GB. Sync 01/10/18 - 72382/13812Kbps @ 600m. (Disabled:BQMs - IPv4 & IPv6)

Thanks Zarjaz. I do have FTTC so it is evidently a loop fault. Hope it isn't too much of a B to locate it for the engineers sake.

...... depends which leg is dis too .

... if the pair is straight A to B then it needs to be the A leg dis allow the broadband to continue to (partially) work.

B leg dis, no dial tone, no broadband.

Thanks, good to know. Loop fault or short circuit can occur indoors as well? I would check by plugging in the telephone into the master socket test port.
