LC1721 disconnect frequently

Beitrag von Henry »

The ADSL-connection on our LC1721 is dropped on irregular intervals. Sometimes it holds for 30 minutes, sometime not even 2. I can't find the problem. All it says is Connection establishment failure (layer 1) [0x3308].
The system info is:
Firmware 6.06.0012
Line type: ADSL over ISDN (Annex B)
Line code: 5.93/e74.02.08
Line mode: G.992.5 (ADSL2+)
Identification DSLAM: Broadcom
Upstream rate: 624 kBit/s
Downstream rate: 9247 kBit/s
Signal-to-Noise ratio: 9.0 dB

Any ideas?

Regards,

Henry

Moin, moin!

There are known problems with ADSL2+ connects. They depend on the DSLAM firmware and the DSLAM chipset. I have seen stable connections with Broadcom based DSLAMs, so it is no general problem with this chipset.

You can try G.992.1 (G.DMT) or use the 6.07 firmware (ADSL only).
