FCC NOTICE
This device complies with Part 15 of the FCC rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a ClassA digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial environment.
This equipment uses, generates, and can radiate radio frequency energy and if not installed in
accordance with the operator’s manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause interference in which case the user
will be required to correct the interference at his own expense.
WARNING: Changes or modifications made to this device which are not expressly approved by the
party responsible for compliance could void the user’s authority to operate the equipment.
IC NOTICE
The Industry Canada label identifies certified equipment. This certification means that the equipment
meets certain telecommunications network protective, operational and safety requirements. The
department does not guarantee the equipment will operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the
facilities of the local telecommunications company. The equipment must also be installed using an
acceptable method of connection. In some cases, the company’s inside wiring associated with a single
line individual service may be extended by means of a certified connector assembly (telephone
extension cord). The customer should be aware that compliance with the above conditions may not
prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility
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
facility, 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 ELECTRICAN, AS APPROPRIATE.
This digital apparatus does not exceed the ClassA limits for radio noise emissions from digital
apparatus set out in the Radio Interference Regulations of the Industry Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables
aux appareils numériques de la class A prescrites dans le Règlement sur le brouillage radioélectrique

PT#
Displays the application ports (bridge ports) available from the host
platform to the WAN. If the active protocol is PPP, Local Management
assigns only one application port per interface number (IF#). If the active
protocol is Frame Relay, Local Management assigns the available WAN
bridge ports from the host platform, one per DLCI.
The quantity of application ports for a Frame Relay network is
determined by the quantity of DLCIs (Data Link Connection Identifiers)
assigned to that Interface. This is determined either manually or by the
Local Management Interface.
IF#
Displays the Interface that is associated with the application port.
LID
Displays the Link Identifier. If the active protocol is Frame Relay, the
Data Link Connection Identifier is displayed. If the active protocol for
this interface is PPP, then PPP appears in this field.
STATE
Displays the status of the application port. If the active protocol is Frame
Relay, this field displays the status as Active, Inactive, or Invalid (no
LMI). If the active protocol is PPP, this field displays UP (active) or
DOWN (inactive).
