This section describes the requirements for compliance with Federal Communications Commission (FCC) Rules and Industry Canada CS-03 standard.

FCC Registration and Requirements

The following paragraphs describe the requirements and information based on FCC rules.


If you experience problem with the Sonus - Sonus SBC 2000 Unified Communications Exchange products, contact Sonus Technical Support Center at 1-800-800-4638 for information on service or repairs. The telephone company can ask you to disconnect the equipment from the network until the problem is corrected or until you are sure that the equipment is not malfunctioning.

FCC Rules, Part 15

The Sonus - Sonus SBC 2000 Unified Communications Exchange has been tested and complies with the limits for a class A 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 generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference in the user's expense.

FCC Rules, Part 68

  1. FCC Part 68 Registration
    The Sonus SBC 2000 Unified Communications Exchange complies with Part 68 of the FCC Rules and the requirements adopted by the Administrative Council of Terminal Attachments (ACTA). On the back of this equipment is a label that contains, among other information, the ACTA labeling identification number US: 1BHISNANUX2000 If requested, this information must be given to the telephone company.
  2. Ringer Equivalence Number (REN)
    The ringer equivalence number (REN) is used to determine the quantity of devices which may be connected to the telephone line. Excessive RENs on the telephone line may result in the devices not ringing in response to an incoming call. In most, but not all areas, the sum of RENs should not exceed five (5.0). To be certain of the number of devices that may be connected to a line, as determined by the total RENs, contact the local telephone company.
  3. Facility Interface Information

    In order to connect registered terminal equipment to the telephone company lines, the terminal equipment must utilize FCC registered jacks. Standardized jacks are used for this equipment.

    The following tables list facility interfaces, manufacturer's network interface port designations, RENs or service codes, and network jacks.

    This table lists the network digital trunk interfaces for digital services.

  4. Disruption of the Network
    If the Sonus SBC 2000 Unified Communications Exchange disrupts the telephone network, the telephone company can discontinue your service temporarily. If possible, the telephone company will notify you in advance. If advance notice is not practical, they will notify you as soon as possible. You are also informed of your right to file a complaint with the FCC.
  5. Telephone Company Facility Changes
    The telephone company can make changes in its facilities, equipment, operations, or procedures that can affect the operation of your equipment. If they do, you should be notified in advance so you have an opportunity to maintain uninterrupted telephone service.
  6. Non-live Voice Equipment
    Non-live voice equipment such as music-on-hold devices and recorded announcers for systems must be approved by and registered in accordance with the ACTA adapted ANSI/TIA-968-B standard, or it must be connected through protective circuitry that is approved by N.E.T. and registered in accordance with the ACTA adapted ANSI/TIA-968-B standard.
  7. Newly Established Network Area and Exchange Codes
    The routing software features allowing user access to the network must recognize newly established network area codes and exchange codes as they are placed in service.

    Failure to upgrade the premises systems or peripheral equipment to recognize the new codes as they are established restricts the customers and the customer's employees from gaining access to the network and to these codes.
  8. Equipment with Direct Inward Dialing (DID)
    Allowing the equipment to be operated in such a manner as to not provide for proper answer supervision is a violation of Part 68 of the FCC rules.
    Proper answer supervision is when:
    1. This equipment returns answer supervision to the PSTN when DID calls are:
      • Answered by the called station.
      • Answered by the attendant.
      • Routed to a recorded announcement that can be administered by the CPE user.
      • Routed to a dial prompt.
    2. This equipment returns answer supervision on all DID calls forwarded to the PSTN. Permissible exception are:
      • A call is unanswered.
      • A busy tone is received.
      • A reorder tone is received.
  9. Hearing-Aid Compatibility
    Telephones for emergency use and telephones installed in common areas such as lobbies, hospital rooms, elevators, and hotel rooms must have handsets that are compatible with magnetically coupled hearing aids. Persons who are not in common areas must also be provided with hearing-aid compatible handsets, if needed.

    FCC required hearing-aid compatible digital telephones comply with the FCC Rules, Part 68, Section 68.316 and 68.317 for used with the Sonus SBC 2000 Unified Communications Exchange.
  10. Programmed Dialer Features
    When you program emergency numbers or make test calls to emergency numbers using N.E.T. products with programmed dialer features, stay on the line and briefly explain to the dispatcher the reason for the call before hanging up. Perform these activities in off-peak hours, such as early morning or late evening.
  11. Connecting Off-premises Station Facilities
    Customers who intend to connect off-premises station (OPS) facilities must inform the telephone company of the OPS class for which the equipment is registered and the connection desired.
  12. Equal Access Requirements
    Call aggregators such as hotels, hospitals, airports, and so on must provide the end-user equal access codes to the carriers of the user's choice. The current equal access codes are 10XXX, 800, 888 or 950.

    The Sonus SBC 2000 Unified Communications Exchange is capable of providing user access to interstate providers of operator services through the use of equal access codes. Modification by aggregators to alter these capabilities is a violation of the Telephone Operator Consumer Services Improvement Act of 1990 and Part 68 of the FCC Rules.
  13. Electrical Safety Advisory
    While the Sonus SBC 2000 Unified Communications Exchange is fully compliant with the FCC rules and regulations, it is recommended that an alternating current (ac) surge arrestor of the form and capability suitable for the model purchased be installed in the ac outlet to which the Sonus SBC 2000 Unified Communications Exchange is connected. Consult with you distributor as to the surge protector requirements for your equipment.

Industry Canada - Equipment Attachment Limitations
