These standards do exist for a good reason, they guarantee
interoperability
with PSTN networks all over the world. So the good news is that testing
is not mandatory,
the bad news is that by skipping them your product may fail in certain
places or even full networks.
As the standards are free, I suggest that at least you read them and
even better
implement the tests in your own development lab....
Note that for a long time the telecom operators had internal test
protocols exceeding TBR21
(we tested their equipment for some time) , to allow their equipment
stand out from
the competition on the market.
The standards mentioned provide for minimum requirements only.

Excellent response Larry. When something sounds too good to be true it
usually is. But not in this case.
Thanks very much,

Hi Carl,
What you have surmised is correct. You are not required to meet any
line standards is order to comply with the directives.
The DoCs you are seeing, is the voluntary testing to ETSI standards to
show that the line interface device is compatible with the phone
network. I asked several times a joint NIST - EU meetings (in the
2000's) about the implementation of TTE standards under the R&TTE
directive and always got the same response. There are no formal
complaints and therefore no implementation of mandatory standards will
occur. Also, the other reason the directive is going to become the
Radio Equipment Directive (RED), as that is all it has ever really
covered.
Of course being a test lab whom does those tests, we can only make a
mild suggestion you should test, as to this day we still have product
showing up that don't comply with the ETSI TBR and or ES 203 021-x
standards, but that is always a financial / business decision on what
the risk is of performing no testing.

Subject: [PSES] TTE Equipment and R&TTE Directive
Dear List Members,
I haven't worked with land-line telecom hardware for many years. I
have a device intended for use by handicapped persons that will enable
a visual alarm if the land-line phone is ringing, so the device is
listen-only.
I've found what appears to be good and reliable guidance concerning
TTE equipment at this link which indicates that TTE equipment need
only comply with the EMCD and LVD:
http://ec.europa.eu/enterprise/sectors/rtte/regulatory-framework/index
_e
n.htm
However, I'm seeing DoCs and product specs for current TTE equipment
that reference the ETSI 201 703 and "TBR" series of standards, and
those standards are not listed under the R&TTED, EMCD, or LVD on the
Europa Harmonized Standards pages.
Can someone shed some light on this confusing issue? Is TTE really
not required to meet a line connection standard of some type as the
Europa link above indicates?
Thanks very much,
Carl
