Hello I have some question for you guys:
I have a 7M/512k DSL Line.
I have a c2651 with a WIC1-ADSL
since the port is limited at 7Mb (aal5 clockrate 7000000) I would like to train ADSL at a lower setting to gain some SNR.
My DSL currently trains at:
gw1.wisp#sh dsl int atm0/0 ATM0/0 Alcatel 20150 chipset information ATU-R (DS) ATU-C (US) Modem Status: Showtime (DMTDSL_SHOWTIME) DSL Mode: ITU G.992.1 (G.DMT) Annex A ITU STD NUM: 0x01 0x1 Vendor ID: 'ALCB' 'TSTC' Vendor Specific: 0x0000 0x0000 Vendor Country: 0x00 0xB5 Capacity Used: 83% 78% Noise Margin: 9.5 dB 14.0 dB Output Power: 20.0 dBm 11.0 dBm Attenuation: 20.0 dB 11.5 dB Defect Status: None None Last Fail Code: None Selftest Result: 0x00 Subfunction: 0x15 Interrupts: 2667 (0 spurious) PHY Access Err: 0 Activations: 2 LED Status: ON LED On Time: 100 LED Off Time: 100 Init FW: embedded Operation FW: embedded SW Version: 3.8131 FW Version: 0x1A04

Is it possibile to force the cisco to train at a lower speed ? something around 7000 ?
How can I work with some settings example dsl noise-margin xx ?
I haven't found a lot of documentations about dsl commands since they are unsupported.
