My Settings in a old and forgotten world of CT1 I have been kind of following this thread, I run T1's and I received zero help from my TELCO, it turns out they had no clue and I was on my own. A Lucent PM-4 Manual really helped me... Here are my settings from my old T1, I am sorry I am not running Hiper stuff ----------------------------------------------------------------------------- 1 T1 Span Line 1 Framing Mode SF 2 T1 Span Line 1 Line Coding AMI 3 T1 Span Line 1 Remotely Initiated Loopback Respond 4 T1 Span Line 1 Jitter Attenuation Transmitter 5 T1 Span Line 1 Transmit Line Build Out 0.0 dB 6 T1 Span Line 1 Automatic Busy-out Disabled 7 T1 Span Line 1 Fractional T1 Byte Pattern FE Hex 8 T1 Span Line 1 Short Haul NIC Line Length Not Applicable 1 Set to Feature Group B Defaults 2 Set to Feature Group D Defaults 3 Set to Loop-start Defaults 4 Set to Ground-start Defaults Current Setting 5 Dial-in/Dial-out Trunk Type E & M type II 6 Dial-in/Dial-out Trunk Start Wink 7 Dial-in Expected Address No Address 8 Dial-in Address Acknowledge Wink Enable 9 Dial-out Address Delay 70 10 Dial-in No-Add. timeout no answer (0 fast-ans) 30 ---------------------------------------------------------------- Now in coming up with this stuff, I tried everything, in north america we do not use ground start anymore, if you are not able to set this kind of stuff maybe your software does not support CT1? Do not use Ground Start; no one in north america does. Hope this helps PS. if anyone can improve on this let me know, Thanks! -Cyrus. cyrus@mtio.net
