# BANDWIDTH GUIDE

### INTRODUCTION

The bandwidth of a circuit connection can be upgraded or flexed in three different ways.

### PERMANENT UPGRADE

On Demand circuit connections purchased under a 3–36 month fixed contract term can be permanently upgraded up to the bandwidth of the port (for example, 1 Gbps) using the "Modify bandwidth" option. Connections can be upgraded within the current contract term, or under a new contract term.

### BANDWIDTH BOOST

The Bandwidth Boost feature allows circuit connections under a fixed term (3, 6, 12, 24 or 36 month) contract to be temporarily upgraded—for example, to meet a short term demand for additional bandwidth.

* Customers are charged a premium for the duration of the boost period.
* The minimum boost period is 1 hour (On Demand / flex pricebook) or 1 day (traditional / fixed pricebook).
* There is no maximum boost period.

At the end of the boost period, the boost should be removed by selecting the original circuit bandwidth (the base bandwidth) via the Bandwidth Boost menu option.

### BANDWIDTH FLEXING

Flexible 1-hour contracts can be upgraded or downgraded in near real time, with a 1-hour billing granularity.

* The upper bandwidth limit is the port speed (e.g., 1 Gbps) at the A and B ends of the circuit.
* The lower bandwidth limit is defined by the bandwidth ranges described in the "Ethernet Connections" page.
* Bandwidths can be flexed up or down at any time.
* There is no restriction on the number of bandwidth changes that can be made within a calendar month.

Note: On Demand is based on flat per-hour billing, not UBB.
