Interface Cards
The interface cards provide the link to the physical network. They receive data
from the network, extract data, and forward the data to the processor cards for
routing. When a processor card has data to send to a port, the interface cards
accept the data and transmit it in the appropriate format.
In this guide, the term interface card refers to the following cards:
• Access interface cards -- T3, ARM, Quad DS3 for channelized AP, Dual
OC-3 SMF and MMF for channelized AP cards, Dual OC-3 SMF and MMF
for ATM access
• SSP interface cards -- SSP interface console and SSP interface Ethernet cards
• Trunk interface cards -- ATM OC-12c/STM-4c SMF and MMF, Quad OC-3
ATM trunk interface, ATM OC-3 trunk phy, and Ethernet SX and LX trunk
interface cards
Access Interface Cards
The Versalar 15000 access interface cards occupy chassis slots 1 to 5 and support
network interfaces for AP cards. The access interface cards are the Hex T3 (T3),
ARM, Quad DS3, or Dual OC-3 interface cards, each of which is described in the
sections that follow. (Note that the ARM interface card must be installed in slot 5.)
