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:
