Re: [hylafax-users] Hylafax+ With E1 card possible ?

["Andrew Rinaldi" <andrew.rinaldi@xxxxxxxxxxxx>]

Hi Michael,

I'd agree with you.... but given that Brooktrout/Eicon account for 95% of
the digital fax market isn't that what matters ?

The most successful digital implementations we have seen are E1/T1 channel
banks with analog fax boards.... this removes the complexity of a PABX and
can be a low cost solution.

What you are talking about sounds like an limitation in the products you
tested, not of E1 circuits.

If I needed lots of lines (IE: More then 10) I would definitely get an E1 +
a PABX even if I used analogue cards at the end.
