Interface and port speeds available by region:
| | U.S. | Europe | | Serial | DS-3 | DS-3 | | POS | OC-3, OC-12, OC-48 | STM-1, STM-4 | | Ethernet | 100BT, Gigabit Ethernet | 100BT, Gigabit Ethernet |
Level 3 runs single mode fiber optic cable to the customers premise. The fiber cable can have any type of hardware on both ends.
For example:
100BT Ethernet / Gigabit Ethernet:
If a customer needs Gigabit Ethernet, Level 3 will have a Cisco router with a Gigabit port on their end.
The customer will have a Gigabit switch with a GBIC (Gigabit Interface Converter) connected to the fiber optic cable.
Optical Carrier Level connections and SDH:
If POS type connection is requested, expensive hardware must be used by both ends.
Level 3 will use Fujitsu Multiplexers:
The customer will need an OC level router, such as the Juniper Networks M20:
Serial Connections - DS3/T3:
The telco needs to run a dedicated DS3 circuit.
The customer needs to have a DS3 Inverse access multiplexer and a router supporting HSSI (High Speed Serial Interface).
One of the HSSI compatible routers is a Cisco 3600 Series:
