this is just passing curiousity.
for those who have used broadcomm NICs and/or anything
from broadcomm, what has been your experience as to the
quality of the hardware/components ?
i ask as i encounter their "bcm v.92" modem on a quasi-daily
basis in the context of supporting dialup customers.
most often a "new dell" with the "bcm v.92" or a "new gateway "
with the re-branded "gtw v.92" modem ( as seen in modem.cpl in
to ~briefly cite my first-hand encounters with them acting poorly:
( outside of hearing them not be able to handshake their way out
of a wet paper bag, quite often )
A - dialup customer had a "new gateway" and 2 phone lines, was
configuring the "new gateway" for our dialup. he also had his
old PC sitting next to the new one. old PC had either rockwell/conexant
or a pctel modem ( by no means excellent ). the old PC could dial
*fine*. when telling the new PC to dial, the modem would pick up
the phone, hear dialtone, and dial the POP# --- and would *NOT*
_break_ the dialtone. ie - you could hear the modem rendering out
the DTMF sounds, but the dialtone persisted. the customer *did* have
the phone cable in the correct jack -- the fix was to switch him to
pulse dialing, whereupon the modem did break the dialtone and connect
B - several seperate customers recently ( from various regions in the US )
with these modems in PCs attempt to dial our POP#s and receive an
"error 678", which could imply that the modem did not hear a handshake attempt
from the other end of the line ( for instance, dialing the wrong #, or
dialing the # with 11 digits ( 1+area code ) in a context where 7 digits
is all the telco will allow for local calls, etcetc ). i've had these
customers pick up their phones and dial the POP# by hand and they do
hear our modem pick up and try handshake -- after 9x checking the # listed
in the dialup window, they are swearing on their grandparents' graves that
they have the # "to be dialed" input identical to that which they dialed
on their receiver --- switching them to pulse dialing also yields success.
so, basically, my only experience with them [broadcomm] is with respect to several
instances of their v.92 softmodem being *inept* at correctly rendering
DTMF signals for tone dialing --- i'm wondering how good their NICs are,
especially in light of seeing their NIC appearing on many motherboards
as an integrated peripheral?.
is broadcomm total trash, or do they just have a poor modem division?
