The OC3/STM1 GE/FE line module pairs with the OC3-2 GE APS I/O module to deliver unchannelized OC3/STM1 ATM operation through two line interfaces and Gigabit Ethernet operation through one line interface.
The OC3-2 GE APS I/O module uses a range of small form-factor pluggable transceivers (SFPs) to support different optical modes and cabling distances, and accepts up to three LC-style fiber-optic connectors. You can configure ports 0 and 1 for OC3/STM1 ATM interfaces; port 2 is reserved for a Gigabit Ethernet interface.
The interface stack for OC3/STM1 ATM interfaces on the OC3-2 GE APS I/O module is the same as for OCx/STMx/DS3-ATM interfaces. (See Figure 5.)
For more information about configuring a Gigabit Ethernet interface on this I/O module, see OC3-2 GE APS I/O Module.
