3 1 Introduction The service Wavelength provides a fixed optical connection through the telecom network which is reserved for the Customer 24 hours a day all the year round. The service Wavelength provides a connection with a high degree of data security, great flexibility for the Customer and very high transmission capacity. Broadnet supervises its WDM-network (WDM: wavelength multiplexing) continuously 24 hours a day all the year round. Wavelengths are available between Broadnet s largest node points. 3

5 3 Service characteristics Wavelength provides a fixed and dedicated optical connection through the telecom network 24 hours a day and offers a connection with a high degree of data security and very high transmission capacity. A wavelength is established directly between two defined connection points and it is physically set up directly in Broadnet s WDM-network. The product is based on international standards for connection of the Customer s devices, and will therefore function optimally together with equipment from most of Broadnets. The product is suitable for establishments with a continuous, large transmission need between two given connection points and particularly for applications that need timely transmission, e.g. for multimedia solutions (speech, video and data). The product is being delivered with various standardized interfaces and transmission velocities and is basis for the Customer s communication network as e.g. SDH, IP-MPLS and ATM networks. 5

6 4 Technical description 4.1 Connection and delivery Customer connection point (CP) will be an optical contact point (ODF). At CP Broadnet may have placed WDM equipment, or the wavelength may be remote-fed over an access connection on Dark Fiber from equipment placed in another location. Broadnet marks each CP with connection number, before notice of completion. Contact point for the Customer s equipment send (named TX ) and receive (named RX ) is to emerge from the labeling. Testing and measuring of wavelength is done according to Broadnet s current routines at any time. Broadnet carries out a functionality test of the wavelength before notice of completion. The Customer must always carry out an acceptance test for himself as soon as possible after Broadnet s notice of completion. Broadnet normally does not test the connection over a longer period. If such testing for example over a 24 hour period should be necessary, this must be agreed separately for a charge. In case of delivery from other access providers, other forms of testing and labeling may occur. Normally the connections will be marked with the access provider s connection number. This connection number will appear on Broadnet s notice of completion to the Customer. 4.2 Description of capacity and interface A connection has a pre-determined capacity, and the whole of this capacity is available for the user. Broadnet may deliver Wavelengths as standardized optical Ethernet interfaces, different OTU interfaces or FiberChannel (FC). Specifications for the relevant transmission speeds and interfaces are indicated in the following table: Service Supervision and quality Wavelength Signal from Customer Signal level Signal to the Customer Signal level ISO/IEC standard (mechanically optical) ITU standard (functionally optical) 1Gbit/s nm -18dBm - 3 dbm nm -8dBm - 0dBm G.707, G.957, G.958 1Gbit/s FC nm - 18dBm - 3 dbm nm -8dBm - 0dBm 2Gbit/s FC 0 dbm -1dBm max 4Gbit/s FC 0 dbm -1dBm max 6

Broadnet might provide 100GBase SR-10 for some long-haul DWDM-systems. Broadnet might provide 100GBase SR-4 for some metro DWDM-systems. Availability on request. 7

8 5 Supplementary services 5.1 Diversity Wavelength may be delivered with the supplementary service diversity. With the supplementary service Diversity Broadnet ensures that two different wavelengths do not have common regulator points through the lifetime of the lines. We perform regular reviews of our network to ensure that the connections have the necessary separation. 5.2 Client Interface Shutdown Client Interface Shutdown may be ordered as a complementary service. Client Interface Shutdown will take Broadnets down interface to customer, in case of failure in Broadnets network. 8

9 6 Technical quality Quality in Broadnet s WDM network is determined by the criteria stated here. The Wavelength Service is delivered with a agreed Service time and a Service Quality Guarantee. 6.1 Service time The Service time specifies the period Broadnet will do fault correction on the Services. The Customer may select Basis, Utvidet or Kontinuerlig Service time. If the Customer wants fault correction outside the agreed Service time, this must be ordered separately as Payed Fault Correction. Additional cost will then be charged for this service. Broadnet is not able to guarantee that Payed Fault Correction always will be available. 6.2 Service Quality Guarantee The supplier s fiber equipment is in large protected against damages that can result in loss of service (cable damage), but the dark fiber service is realized as a point-to-point connection without protection/re-routing. Therefore, the customer is responsible for assuring re-routing of services in its own network. The following Service Quality Levels are available for Wavelength: Parameters Guarantee 1 Guarantee 2 Guarantee 3 Service Availability per quarter 99,00% 99,50% 99,60% Physical fault correction (Guaranteed time to repair) < 20 hours < 10 hours < 8 hours Terminal based fault correction (Guaranteed time to repair) < 16 hours < 8 hours < 4 hours Access type Singel Singel Singel Responstime < 2 hours < 2 hours < 1 hour Feed back from NOC < 2 hours < 2 hours < 1 hour Table 4 Specification of Service Quality Guarantee 6.3 Procedure for Rectification Broadnet supervises Wavelength around the clock all the year round. Broadnet s operation centre will discover many types of error, and will then notify the Customer about this within AST. In the cases when the Customer discovers an error on the service which he has not been notified about, notification to Broadnet must be sent as soon as possible. Before the Customer notifies errors to Broadnet, it is essential that the own equipment is checked. If a customer-notified error proves to lie with the Customer s equipment, then Broadnet will get paid for the troubleshooting. If an error or a problem arises, the necessary investigations and troubleshooting measures shall be initiated according to Broadnet s specifications for error handling. Errors may be reported by phone or . Broadnet s Customer Service need the following information: Connection number Description of the error Modem status (if possible) and confirmation that the own equipment has been checked 9

10 Telephone number and address to contact person at Customer for testing and access Time when the error was discovered Concerned address (where this applies) Any other relevant information Error reports and confirmations are reported to the Customer by phone or according to approved procedure. 6.4 Delay Wavelength produced in Broadnet s SDH network gives little delay. A typical one-way delay between Oslo and Bergen for example is between 4 ms and 8 ms, and between Oslo and Tromsø between 10 ms and 12 ms. 6.5 Error in transmission SESR and ESR on the connection in Broadnet s network are measured according to the current ITU-T recommendations G.821 and G.826. The quality of the connections in Broadnet s network shall conform to the following quality level: Criteria Severely Errored Seconds Ratio (SESR) <0.03% Errored Seconds Ration (ESR) <0.75% Table 5 Quality, measuring period per quarter. Quality level 10

11 7 Prices 7.1 Price structure The prices for Wavelength are stated with start-up price and a monthly price based on air route length between Customer address A and Customer address B. Prices for such things as internal cabling will come in addition, removals and other work that is not included in the start-up price. 7.2 Termination after end of contract period For Wavelength the termination period is 3 months from the first date in the following month. 7.3 Termination before end of contract period If the Customer wishes to cancel individual accesses during the lock-in period, before the expiry of the contract period, all of the remaining lease sums must be paid. Circuits in contract period can be cancelled with a 3-month notice. Such cancellations are effective from the day the outstanding balance is paid. 11
