Introduction
NEW
Ordering a new EVPL (Ethernet Spoke) connection?
Check out the new 1-step ordering feature here.
Ports are used to terminate circuit connections. Under the On Demand model, ports are a separate component - unlike the traditional data networking model where ports are an integral part of a circuit connection.
Ports are available in 1Gbps & 10Gbps speeds. In key data centres 100Gbps ports are also supported. The full physical On Demand port bandwidth (e.g. 1Gbps) is reserved between the customer’s site and Colt’s core network. Logical ports (e.g. 100Mbps on a 1Gbps physical port) are no longer available for new orders.
Colt supports a full range of physical 1Gbps, 10Gbps & 100Gbps port specifications:
| 1000Base-LX | 10GBASE-LR | 100GBASE-LR4 |
| 1000Base-SX | 10GBASE-SR | 100GBASE-SR4 |
| 1000BaseT | ||
Where a 1000Base-T interface is required the port is configured with autonegotiation enabled. Colt does not support the manual configuration of 10Base-T or 100Base-T ports by disabling autonegotiation; autonegotiation is always enabled by default.
In the On Demand portal, ports are reserved by first selecting the required on-net building via the Google Maps interface, and then selecting the required port speed and interface type.
New ports can be requested in the default shared area (e.g. an MMR in a data centre) or in a specific room – for example, the comms room on the third floor of an enterprise building. Customers are encouraged to select the default shared area as the On Demand platform will automatically select ports that are available via near real time delivery.
The On Demand portal shows ports that can be reserved in near real time (shown with a green tick) and ports that require a network capacity build (shown with a grey “plus” sign).
IMPORTANT! On Demand ports stay in a deactivated state until a circuit connection is added to the port. Customers can request that a new port is tested prior to a circuit being added by raising a ticket via the standard support process.
Port charges
Under the default On Demand flex pricing model, customers are required to make a 3 or 12 month commitment. Monthly recurring rental charges then apply.
In enterprise buildings, the minimum commitment is 12 months – customers are also charged a small installation fee to cover the cost of adding the new port capacity.
Under the fixed pricing model, customers are not required to make a commitment on the port. Under the fixed model, .Customers are charged a one off installation fee when a new port is added.
Please refer to the pricing section for more further details.
Requesting a cross connect
Ordering a cross connect from a data centre operator
At data centre sites, customers are able to generate an LOA from the On Demand portal to grant the Data Centre permission to access the Colt rack to facilitate the termination of DC cross connects. The LOA should be submitted to the DC operator when the cross connect order is placed.
Where a cross connect is requested, customers are required to enter the demarcation details and are also required to upload a letter of authority to grant Colt permission to place a cross connect order to the customer rack. The demarcation details and LOA are mandatory.
Ordering a cross connect from Colt
Alternatively, customers can request a fibre cross connect in a data centre via the On Demand platform, which will result in Colt placing a request being placed on the data centre operator for a cross connect between the specified On Demand port and the demarcation point in the customer rack.
When a new port is requested, customers are asked whether a cross connect is required.
Please note that only fibre cross connects are supported - copper cross connects are not supported.
Where a cross connect is requested, customers are required to enter the demarcation details and are also required to upload a letter of authority to grant Colt permission to place a cross connect order to the customer rack. The demarcation details and LOA are mandatory.
Cloud ports
Cloud connections must be terminated on a cloud port - either a virtual cloud port for hosted services or a physical cloud port for AWS dedicated services.
Please refer to the cloud connectivity section for further details.
Multiservice ports
All On Demand ports are capable of supporting multiple service types, using VLAN segregation. Example use cases include:
For further details on VLAN configurations supported on the Colt On Demand platorm, please refer to the On Demand Connections section.
