Centrex Service

Centrex is a generic term for central office-based telephone services. Centrex provides an alternative to private branch exchange (PBX) service or flat business service. DIS Centrex service includes free calling within the local exchange area, access to the SCAN long distance network, and access to the local operator and emergency services. DIS Centrex offerings also include an abbreviated dialing plan (3, 4, or 5 digits) that can be used to dial between any two phones that are in Centrex. Access to either SIMON, the State’s Simon voice messaging system, or a vendor-specific voice mail solution is also typically available at reduced rates. Centrex lines may be terminated on either individual phones or electronic key telephone systems (EKTS). If used with an EKTS, the intelligence in the EKTS may be used to provide additional functionality.

DIS has established contracts for the provisioning of Centrex services with the following vendors. The brand specific name for the vendor's Centrex product is listed in parentheses.

• Qwest (Centrex Prime)
• Verizon (CentraNet)

3. SCAN/Toll Charges:

   Charges for SCAN or toll calls are the customer’s responsibility

Cost comparisons:

DIS will help public organizations analyze their current local telephone service costs to determine if DIS service is a good alternative. When comparing costs

DIS customers should note that DIS rates include all cost components including tax

It is not unusual for competitive quotes from other service providers to omit various federal and state mandated fees and taxes that are “understood in the industry”. These costs, which frequently add several dollars to the cost of a line, may include charges for the End User Line Charge (EUCL), Common Access Line Charge (CALC), Network Access Registers (NARS), Primary Interstate Carrier (PIC), Local Number Portability (LNP), feature charges, state and local 911 charges, Americans with Disabilities Act (ADA), Washington State Telephone Assistance Program (WTAP), and state and local taxes.

Electronic Key Telephone Systems (EKTS)

DIS has Master Contracts in place for EKTS that can be used with Centrex service. These contracts meet the state requirements for competition and are available for use by customers eligible for DIS services to purchase EKTS systems.

DIS assigns a service representative to each of its customers. The customer service representative will process any orders for new service, moves, additions or changes and coordinate them with the responsible vendor. The DIS customer service representative will also provide the customer information on products and assist in the resolution of any problems that may be encountered with the vendor.
