Interesting that you mention that!
We were told by both MultiTech (modem maker) and ITC (Independent Technologies - loop current attenuator maker) that the sweet spot for our modems was 23-27 milliamps. The line defaults to 24.6 (if you can trust my antique Fluke and the Telco's fancy meter) but the line appears a bit "hot" at 52 volts (DC). I understand that 48 volts is what is normal or the "tariff".
We have set the attenuators at 23.4 milliamps, we seem to get the least number of garbage transactions at that setting. However, at least 20-30% of our extremely short (~200 byte) transactions are trash and, as shown in our system logs and the client's receipts.
I will ask them to double check that. BTW, can I call LiteSpan directly? I assume they don't want to hear from an end-user, just the LEC.
Thanks again for the tip.
