Answered Question
Dec 17th, 2007


I have a Cisco 837 and wondered if the DSL FW can be upgraded like the 877's can? Here's it's output.

Router#sh dsl int atm0


Modem Status: Showtime (DMTDSL_SHOWTIME)

DSL Mode: ITU G.992.1 (G.DMT)

ITU STD NUM: 0x01 0x01

Vendor ID: 'ALCB' 'GSPN'

Vendor Country: 0x00 0xFF

Capacity Used: 96% 59%

Noise Margin: 4.0 dB 14.0 dB

Output Power: 19.0 dBm 3.5 dBm

Attenuation: 45.5 dB 31.5 dB

Defect Status: None None

Last Fail Code: None

Selftest Result: 0x00

Subfunction: 0x15

Interrupts: 646 (1 spurious)

Activations: 1

It disconnects a few times a day, if not I guess I will have to upgrade to an 877.


I have this problem too.

Hi, according to:

you are running latest FW and cannot be upgraded. Some tweaking can be tried with dsl command, but personally I'm always a bit way of that.

Hope this helps, please rate post if it does!
