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 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.

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.

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.

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.

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 e-mail.
Broadnet’s Customer Service need the following information:
broadnet.no
8

Connection number

Description of the error

Modem status (if possible) and confirmation that the own equipment has been checked

Telephone number and e-mail 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 e-mail 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
Quality level
Severely Errored Seconds Ratio (SESR)
<0.03%
Errored Seconds Ration (ESR)
<0.75%

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 payd.
Circuits in contract period can be cancelled with a 3-month notice. Such cancellations are effective from the
day the outstanding balance is paid.
