Problem monitoring modems stats from multimodem

[akourouma at eti.net.gn (ETI - KOUROUMA Aboubacar)]

Hi every body,
    Can you someone tell me how to configure MRTG geting 
modem  stats from a Mini Array III Multimodem (Multitech)? I have
already configured the SNMP agent on the Mini array as following:
SNMP Agent                              
:    enabled
Trap Manager Community Name           
:    community1
Trap Manager IP Address                
: xxx.xxx.xxx.xxx (IP address)
Trap Manager Port Number              
: 161
SNMP Reboot Required Trap              
:    enabled
Get Community Name                      
:    community1
Get Community Permission               
:    readonly
Set Community Name                     
:    community2
Set Community Permission              
:    readwrite
Authentication                          
:            Simple
Community Name

but when from the command prompt I run c:\mrtg-2.8.12\run cfgmaker community1 at xxx.xxx.xxx.xxx > mrtgras.cfg I get error message

SNMPGET Problem for sysDescr sysContact sysName sysLocation ifNumber sysObjectID on community1 at xxx.xxx.xxx.xxx
SNMP Error: no response received
SNMPv1_Session (remote host: "xxx.xxx.xxx.xxx" [xxx.xxx.xxx.xxx].161
                  community: "community1"
                 request ID: 956836245
                PDU bufsize: 8000 bytes
                    timeout: 2s
                    retries: 5
                    backoff: 1)
    I am running mrtg-2.8.12 on Win NT. It is monitoring well traffic on my router but not from my multitech multimodem.
Cheers,
