ONS 15454 Ethernet Solutions 
Cross-Reference Charts, page 166 

 

 

 
The E-Series cards incorporate layer 2 switching, while the G series card is a straight mapper 
card.  The ONS 15454 E-Series include the following Ethernet cards: 
 

   E100T-12 

   E100T-G 

   E1000-2 

   E1000-2-G 

 
Each E100T-12 and E100T-G card has 12 front panel (user side) 10/100 Mb/s Ethernet ports and 
12 STS-1 connections (622 Mb/s aggregate bandwidth to the cross-connect card) to the transport 
side of the network.  Each of the user side Ethernet ports can be set for autosensing.  
Autosensing enables the ports to detect the speed of an attached Ethernet device by auto-
negotiation and automatically connect at the appropriate speed and duplex mode (half or full 
duplex), and also determine whether to enable or disable flow control. 
 
The E1000-2 and E1000-2-G provides 2 modular GBIC (Gigabit Interface Connector) slots ports 
and 12 STS-1 connections to the internal interface ports on the transport side of the network.  
Each GBIC slot can be populated with either 1000Base-SX (short reach over multimode fiber at 
850nm) or 1000Base-LX (long reach over single mode fiber at 1310nm).  The slots are assigned 
to 12 STS-1s based internal interface transport ports.  Figure 5-1 is a block diagram of the E-
Series cards.
