Re: RAS Connection speed

ensure your modems are not set to 19K. try hard setting them to 30K or more.

ensure your carrier PSTN is certified for modems not telephones.

Re: RAS Connection speed

Here is how my modems are set-up:

line 33 48

exec-timeout 0 0

flush-at-activation

modem InOut

modem autoconfigure discovery

no exec

transport preferred none

transport output none

flowcontrol hardware

I also upgraded my IOS from 12.2(11)T to 12.2(15)T, this updated the modem firaware... (show modem version)

Good Luck

Re: RAS Connection speed

NM-AMs in 2600 are very sensitive and needs proper grounding of chassis.

I have seen some similar issues in the past where modems will give low connect

speeds in the absence of proper grounding. Also make sure there is no RFI (Radio Frequence Interference) nearby. Please see the following for more on how to ground the chassis :
