To get an official word e-mail to support@livingston.com ... ;)
Perhaps the newer unit has more memory? 4MB rather than 1MB. What I
would be more concerned with is actualy throughput. If there's no
differential, then the ping times just mean that the 30 modem boxes are
putting a lower priority to icmp due to higher amounts of packets. Note:
icmp is at the bottom of the list of processing priority.
