that the equipment meets telecommunications network protective, operational and safety
requirements as prescribed in the appropriate Terminal Equipment T echnical Requirements
document(s). The Department does not guarantee the equipment will operate to the user’s
satisfaction.

Before installing this equip men t, u sers shoul d ensu re that it is pe rmis sible to be conn ected
to the facilities of the local telecommunications company. The equipment must also be
installed using an acceptable method of connection. The customer should be aware that
compliance with the abov e conditi on s may not prevent the degradation of service in some
situations.

Repairs to certi f i ed equip men t should be coo rdi nated b y a r epre senta ti v e de sign ate d by the
supplier. Any repairs or alterations made by the user to this equipmen t, or equipment
malfunctions, may give the telecommunications company cause to req uest the user to
disconnect the equipment.

Users should ensure for the ir own protection that the electrical ground connections of th e
power utility, telephone lines and internal metallic water pipe system, if present, are
connected together. This precaution may be particularly important in rural areas.

Caution: Users should not attempt to make such connections themselves, but should
contact the appropriat e electric inspection authority, or electrician, as appropriate.

Notice: For equipment using loopstart lines, please note that the Ringer Equivalence
Number (REN) assigned to each terminal device provides an indication of the maximum
number of terminals allowed to be connected to a telephone interface. The termination on
an interface may consist of any combination of devices subject only to the requirement that
the sum of the Ringer Equivalence Numbers of all the devices does not exceed 5. The REN
is located on the “FCC Rules Part 68” label located on the bracket of the module, or on the
back of the unit.

Canada CS-03 -- Règles et règlements

Avis: L'étiquette d'Industrie Canada identifie le matériel homologué. Cette étiquette
certifie que le matériel est conforme aux normes de protection, d'exploitation et de sécurité
des réseaux de télécommunications, comme le prescrivent les documents concernant les
exigences techniques relatives au matériel terminal. Le Ministère n'assure toutefois pas que
le matériel fonctionnera à la satisfaction de l'utilisateur.

Avant d'installer ce matériel, l'utilisateur doit s'assurer qu'il est permis de le raccorder aux
installations de l'entreprise locale de télécommunication. Le matériel doit également être
installé en suivant une méthode acceptée de raccordement. L 'abonné ne doi t pas oublier
qu'il est possible que la conformité aux conditions éno ncées ci-dessus n'empêche pas la
dégradation du service dans certaines situations.

Les réparation s de matériel homologué doivent être coordonnées par un représentant
désigné par le fournisseur. L'entreprise de télécommunications peut demander à
l'utilisateur de débrancher un appareil à la suite de réparations ou de modifications
effectuées par l'utilisateur ou à cause de mauvais fonctionnement.

Pour sa propre protection , l'utilisateur doit s'assurer que tou s les fils de m ise à la terre de la
source d'énergie électrique, des lignes téléphoniques et des canalisations d'eau métalliques,

s'il y en a, sont raccordés ensemble. Cette précaution est particulièrement importante dans
les régions rurales.

Avertissement: L'utilisateur ne doit pas tenter de faire ces raccordements lui-même; il
doit avoir recours à un service d'inspection des installations électriques, ou à un électricien,
selon le cas.

Avis: Veuil lez prendre note que pour tout appareillage supportant des lignes de type
“loopstart,” l'indice d'équivalence de la sonnerie (IES) assigné à chaque dispositif terminal
indique le nombre maximal de terminaux qui pe uvent être raccordés à une interface. La
terminaison d'une interface téléphonique peut consist er en une combinaison de quelques
dispositifs, à la seule condition que la somme d'indices d'équivalence de la sonnerie de tous
les dispositifs n'excède pas 5. Le REN f igure su r l’étiquette “FCC Ru les P art 68” situ ée sur
le support du module ou à l’arrière de l’unité.

right corner of the ISDN connector. This LED has the following
operation:

• Flashes at 8 Hz (rapid flashing) for 0.5 seconds when the host
is attempting to establish a link between the BRI-U mo dule
and the ISDN network switch.

• Flashes at 1 Hz (slow flashing) when a link is established and
the host is operating normally, whether or not it is sending
data.

• Is off if the unit is not receiving a signal. This means that the
host is not connected to the telephone line or the ISDN
network switch is no t responding. Contact the telephone
company if you believe the ISDN network switch is not
responding.

The LED should not remain on constantly. If it does, there is a
faulty electrical connection inside the host, and you should seek
technical support as follows:

• If you purchased a service contract for your Bay Networks
product from a distributor or authorized reseller, contact the
technical support staff for that distributor or reseller for
assistance.

• If you purchased a Bay Networks service program, call
1-800-2LANWAN.
