Canada Requirements Only
Repairs to certified equipment should be coordinated by a representative designated by the supplier. Any repairs or
alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications
company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of the 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 appropriate 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.

Av i s : 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 doit pas oublier qu'il est possible que la conformité aux conditions énoncées ci-dessus
n'empêche pas la dégradation du service dans certaines situations.
Les réparations 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 tous les fils de mise 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.
Av i s : Veuillez 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 peuvent être
raccordés à une interface. La terminaison d'une interface téléphonique peut consister 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

Installing T1 Link Modules in BN Platforms
Removing a Link Module
If there are no empty slots in your BN platform, you must remove a link module to
install the T1. When replacing a configured link module, you must delete all
configured circuits (ports) from the slot so that the BN platform software can
properly configure the new link module.
When replacing a Dual MCT1 link module with a Quad MCT1 (QMCT1
Note:
or QMCT1-DS0A) link module, you do not need to reconfigure Ports 1 and 2;
if, however, you intend to use Ports 3 and 4 on the QMCT1 or QMCT1-DS0A,
you must reconfigure the entire slot.
Refer to Configuring Routers if you have router software or Getting Started with
Site Manager if you have BayStream software for instructions on editing a
configuration file and deleting circuits.
The Backbone Node hot-swap feature allows you to remove or replace a link
module with the chassis power on or off.
Danger: Do not remove more than two adjacent modules with the power on.
1-4
When you remove a link module with the power on, the services that slot provides
become disrupted. After the slot fails to receive packets, the other link modules in
the chassis resynchronize their routing tables and continue uninterrupted.
The procedure for removing a link module is the same for the BLN, BLN-2, and
BCN platforms:
1. Disconnect any exterior cables from the link module.
2. Attach an antistatic wrist strap.
BN platforms and link modules ship with an antistatic wrist strap. You must
wear one of these straps when accessing components on BN platforms. The
antistatic wrist strap directs the discharge of static electricity from your body
to the chassis, thereby avoiding discharge and possible damage to sensitive
electronic components.
Caution: Electrostatic discharge can damage hardware. Always use the
antistatic wrist strap when handling any component on your BN platform.

Configuring Jumper Settings
The following T1 link modules contain at least one user-configurable jumper
setting:
• Dual T1 (Order Nos. 5200 and 5201)
• QMCT1 (Order No. AG2111007)
• QMCT1-DS0A (Order No. AG2104052)
Before you install any of these link modules, make sure the jumper settings on the
link module match your configuration. The following sections describe only the
user-configurable jumper settings; changing the settings of any other jumpers on
the link module can jeopardize module functioning.

Note: A T1 link module normally reports a yellow alarm whenever it receives
a 0 in Bit 2 of 256 consecutive channels. Nortel Networks uses several
encoding algorithms to prevent the reporting of a false alarm when a normal
data stream contains a 0 in this bit.
The DACS T1-64K link module (Model 5200; Order No. 101667) uses a
proprietary encoding algorithm to accept an all 0s condition without reporting
a false yellow alarm. However, a DACS T1-64K link module must be installed
on the receiving end to decode the data.
The DACS T1-56K link module (Model 5201; Order No. 100831) sets Bit 7 of
every channel to a 1 to prevent the false yellow alarm. Even if an all 0s
condition occurs, the 1 maintains frame synchronization. You can use any
standard T1 link module on the receiving end, but bandwidth will be reduced
to 56 Kb/s.
