PRI if this all works out. So rather than introduce 0/1/0 as a potential source of trouble, why not just get calls working from 0/0/0 to 0/1/1 and leave 0/1/0 out of the picture. Might mean having to schedule some downtime around the transition, but retraining
10 times then failing isn’t exactly uptime anyway.<o:p></o:p></span></p>

<p class="MsoNormal">Help! I have a single telco PRI terminated in a RAS (dial-up V.90 modems) that is only serving a few users at this point, but they don't have any other access options (other than satellite) so we continue to run it...<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I would like to move the access numbers to our main PRI that terminates in an MGCP gateway on a Cisco 2811 and then provide a "network side" PRI from that same 2811 to the RAS box so I don't have to pay for a full PRI for just a few concurrent
users.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Everything seems to work except when I route the PRI through the 2811, negotiated speeds drop way down and retrains go way up. Often a modem will retrain 10 times and just give up.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">The incoming PRI (from telco) and the outgoing PRI (towards RAS) are both on the same 2811, so I presume packet loss and jitter shouldn't be an issue -- I am wondering if it is somehow a clock issue? Do I just give up because this is unrealistic?<o:p></o:p></p>

<p class="MsoNormal">Here is the relevant IOS config - 0/0/0 is my normal voice PRI, 0/1/0 is the PRI normally going directly to the RAS , 0/1/1 is the PRI provided to the NAS (note the isdn protocol emulate network)<o:p></o:p></p>
