Until now, our HDM T1 NICs have said under inventory "3COM T1/E1 HDM NIC". The last six we have installed from the 3COM Double-Play program say "3COM T1/E1 LH/SH NIC with Programmable Loopback Relays". I am assuming that LH/SH stands for "long haul / short haul", but what other changes are in the new NICs if any? Of note is that the matching NACs have product codes of 3C4, as opposed to all others installed with a product code of 10Q. All ideas and answers appreciated.
