- The exceeding minimum bandwidth, which may change upward or downward, at NET’s discretion, shall be charged, at a higher or lower amount, in 01 (One) by 01 (One) steps based on the same unit value of the initial Mbps.

3 – CONDITIONS FOR SERVICE DELIVERY

Internet Access Service shall be delivered ON DEMAND, which refers to net bandwidth, free from ATM/Sonet transmission protocol overhead, limited to the Access speed on each location described on the table on item 1.1.

In case it is necessary to increase Access capacity in a specific location, we request a 60 day previous notice, by writing, in order to meet this demand.

3.1 – SLA

For quality standard purposes, the performance levels guaranteed by Via Embratel IP Network (Internet) shall be used, as presented in the table below:

Parameter	Definition	Goal
Latency (milliseconds)	Average transit time (in ms, roundtrip) of a 64 byte packet between two designated points, within Via EMBRATEL Internet Network	75 (maximum)
Loss of Packets (%)	Ratio measuring the average success rate of the transmission of IP packets between two network points	1 (maximum)
Availability (%)	Backbone availability (minimum value)	99,90 (minimum)
Availability (%)	Average time (percentage) in which Via EMBRATEL Internet Network is operational, during the 30 day period corresponding to service subscription	99,85 (minimum)
Scheduled Maintenance	Communication time prior to performing planned maintenance within Embratel Network	15 days
Emergency Maintenance	Communication time prior to performing emergency maintenance within Embratel Network	8 hours

The Parties agree that, if Embratel fails to achieve the indexes reflecting the quality parameters established with Net Serviços, for a period equal or longer than 3 (three) consecutive months, Net Serviços may cancel the circuits where the goals were not achieved, by sending a written notification to EMBRATEL, not being obligated to pay any penalties for this cancelling, or the Parties shall jointly establish another penalty. The Parties agree that this item shall prevail over provisions of item 4.1 (RESCISSION), in the event of default by EMBRATEL regarding the established quality parameters.

3.2 – Recovery Time

Embratel is committed to respond, in a time no longer than 4 hours, to 90% of the events under its responsibility, except for failures arising from Accesses and Equipment owned by Net Serviços.

3.3 – Penalties

Once a failure is identified in services under EMBRATEL’s responsibility, a discount shall be granted to Net Serviços. Failures in services can be understood as interruptions and defects affecting connectivity between Net Serviços’s network and Via EMBRATEL Internet Network, including:

Defects in Via EMBRATEL Internet Network;
Defects identified in Client access circuits to Via EMBRATEL Internet Network, being EMBRATEL responsible for the services (access circuit; modem from EMBRATEL; radio system provided by EMBRATEL; or physical link of the Telecommunications Operating Company, hired through EMBRATEL);
Defects identified in components of Client access circuit to Via EMBRATEL Internet Network, whenever EMBRATEL is responsible for part of the access solution.

The discount to be granted in these events shall be calculated according to the following formula:

Vd = T x P / 1440

where,

P = Price of the monthly service subscription;

T = Number of 30 (thirty) minute interruption periods;

Vd = Discount value in R$ (real)

For discount purposes, the minimum failure period to be considered consists of 30 (thirty) consecutive minutes. Additional failure periods, even being fractions of 30 (thirty) minutes, shall be considered, for discount purposes, as full 30 (thirty) minute periods. The discount shall be calculated based on total interruption volume in a month.

Important: To be eligible to discounts, the Client must register the failure in Internet Tele-Service Center, and the claim must be considered valid, under EMBRATEL's responsibility - 0000-000-0000
