below two posts I made about 2 months ago.
Some OID's for modems and analog/digital connections on MAX routers.


You should be able to add the values from all routers within mrtg.
I've no example handy, but there are many on the list.
Try a search on ascend. Because of some problems with ascends
snmp-implementation, you'll find some examples.

Try querying the OID directly with something other than MRTG. If you 
get a response that makes sense, your MRTG Options are a problem. If 
you don't get a valid response back, the OID is incorrect for your 

I graph modems, etc. on a TNT and use these options:

Options[calls]: gauge, integer

Using absolute _and_ gauge, as in Daniel's example, may be a problem.

I use the following on a TNT. Things will be somewhat different on 
your Maxen, but it gives an idea of how Ascend does things:

Target[calls]: at router
Title[calls]: Max TNT incoming calls
Directory[calls]: internal
PageTop[calls]: <H1>Max TNT incoming calls</H1>
MaxBytes[calls]: <the number of DS0s you have>

ShortLegend[calls]: calls
YLegend[calls]: Calls

LegendO[calls]: ISDN:&nbsp;
Legend1[calls]: Current modem calls (callCurrentAnalogIncoming)
Legend2[calls]: Current ISDN calls (callCurrentDigitalIncoming)
Legend3[calls]: Maximum modem calls
Legend4[calls]: Maximum ISDN calls

Options[sessions]: gauge, growright, integer
Unscaled[sessions]: ymwd

Look in the docs for the MIBS used by your equipment. It'll help you 
find the OID for your need, and also clue you in to some of the 
information that's available. The TNT docs give a nice overview of 
the Ascend MIB hierarchy that I haven't seen in Ascend's other 
manuals, and much of the information is applicable. You can get it 
from Ascend's FTP site.

As for the number of lines, on the TNT each PRI has an OID of it's 
own, so you have to add each OID together to sum them up. Therefore, 
the OID will vary by the slot in use. Here's an example of a hunt 
group using two PRI, each 23B+D:

Target[twoprihuntgroup]: at rout
  + at rout
Title[twoprihuntgroup]: Max TNT two PRI hunt group
Directory[twoprihuntgroup]: internal
PageTop[twoprihuntgroup]: <H1>Max TNT two PRI hunt group</H1>
#AbsMax[twoprihuntgroup]: 46
Options[twoprihuntgroup]: gauge, growright, integer
ShortLegend[twoprihuntgroup]: Calls
YLegend[twoprihuntgroup]: Calls
LegendI[twoprihuntgroup]: Calls:&nbsp;
Legend1[twoprihuntgroup]: Calls
Legend3[twoprihuntgroup]: Maximum calls
#Legend4[hunt3]: Maximum calls
Unscaled[twoprihuntgroup]: dwmy
