Re: (ASCEND) HA-192 on TNT 2.0.7
Dear
I think that it should be design as local needs.
In E1 environment, they needs 32channels for E1 so Ascend should make
different hardware design for each requirement of T1 or E1.
In Korea we need 32 channels on MAX40XX, but for TNT we need 240 Channels
for 8E1 card.
It will be better to design as different for E1 country or T1 country.
In addition 192 HDLC card was reduced as 96 channels on 2.0.7.
I wish this problem fixing as soon as possible or not supply it to customer
as new 192channels card.
Thanks,
S.Y.Kim
