John,

The general approvals scheme GAS (unfortunate acronym) and Manufacturer's
declaration of conformity (MDC) both have pros and cons.  Both schemes are
operating although there are caveats to using them.

The GAS covers single line PSTN equipment and no longer requires you to submit
a sample to TAS for testing.  Should you use the GAS, you are unable to apply
the TAS type approval marking which is widely recognised in the Singapore
marketplace.  With the GAS, you are still required to comply with the relevant
TAS standard (PSTN 1), so unless you have in-house facilities capable of
performing this testing, you will still need to have it tested "somewhere".
Should you wish to apply the TAS approval mark you can still use the standard
type approval route.

The MDC procedure covers most RF products and some multi line equipment and
has major advantages for manufacturers with comprehensive test data.  Note
ISDN products must still use the standard type approval route.  In practice,
TAS want to see test reports answering clauses contained within the various
TAS specifications.  If your test reports do not address the clauses raised,
you may be forced to go the standard TAS testing path (as I recently found
with a low power RF device).

Be aware that you still need a company or person resident in Singapore with a
line transmission dealers license to hold the approval and for their dealers
license number to appear on the label of the equipment (in the case of the
GAS). At the risk of being accused of gratuitous advertising, our office
recently gained a TAS dealers license to assist manufacturers that don't have
a local office.
