The.�otebook.PC.with.internal.modem.model.complies.with.JATE.(Japan),.FCC.(US,.Canada,.
Korea,.Taiwan),.and.CTR21..The.internal.modem.has.been.approved.in.accordance.with.Coun-
cil.Decision.98/482/EC.for.pan-European.single.terminal.connection.to.the.public.switched.
telephone.network.(PST�)..However.due.to.differences.between.the.individual.PST�s.pro-
vided.in.different.countries,.the.approval.does.not,.of.itself,.give.an.unconditional.assurance.
of.successful.operation.on.every.PST�.network.termination.point..In.the.event.of.problems.
you.should.contact.your.equipment.supplier.in.the.first.instance.
Overview
On.4th.August.1998.the.European.Council.Decision.regarding.the.CTR.21.has.been.published.
in.the.Official.Journal.of.the.EC..The.CTR.21.applies.to.all.non.voice.terminal.equipment.with.
DTMF-dialling.which.is.intended.to.be.connected.to.the.analogue.PST�.(Public.Switched.
Telephone.�etwork)..
CTR.21.(Common.Technical.Regulation).for.the.attachment.requirements.for.connection.to.
the.analogue.public.switched.telephone.networks.of.terminal.equipment.(excluding.terminal.
equipment.supporting.the.voice.telephony.justified.case.service).in.which.network.address-
ing,.if.provided,.is.by.means.of.dual.tone.multifrequency.signalling.
Network Compatibility Declaration
Statement.to.be.made.by.the.manufacturer.to.the.�otified.Body.and.the.vendor:.“This.dec-
laration.will.indicate.the.networks.with.which.the.equipment.is.designed.to.work.and.any.
notified.networks.with.which.the.equipment.may.have.inter-working.difficulties”
Network Compatibility Declaration
Statement.to.be.made.by.the.manufacturer.to.the.user:.“This.declaration.will.indicate.the.
networks.with.which.the.equipment.is.designed.to.work.and.any.notified.networks.with.
which.the.equipment.may.have.inter-working.difficulties..The.manufacturer.shall.also.as-
sociate.a.statement.to.make.it.clear.where.network.compatibility.is.dependent.on.physical.
and.software.switch.settings..It.will.also.advise.the.user.to.contact.the.vendor.if.it.is.desired.
to.use.the.equipment.on.another.network.”
Up.to.now.the.�otified.Body.of.CETECOM.issued.several.pan-European.approvals.using.CTR.
21..The.results.are.Europe’s.first.modems.which.do.not.require.regulatory.approvals.in.each.
individual.European.country.
Non-Voice Equipment
Answering.machines.and.loud-speaking.telephones.can.be.eligible.as.well.as.modems,.fax.
machines,.auto-dialers.and.alarm.systems..Equipment.in.which.the.end-to-end.quality.of.
speech.is.controlled.by.regulations.(e.g..handset.telephones.and.in.some.countries.also.
cordless.telephones).is.excluded.
