OC3-ATM2 card
An OC3-ATM2 card provides one 155.52Mbps interface for connecting to an ATM switch. At
a minimum, you must enable the line and specify a dedicated (nailed) group. MAX TNT units
use the nailed group to direct traffic to the interface.
The OC3-ATM2 cards can be used to route IP over ATM or perform layer 2 switching between
ATM and Frame Relay network. The following three versions of this card are available:
•
TNT-SL-UOC3CP-C—with a copper interface
•
TNT-SL-UOC3SF-C—with an optical fiber interface, for short-haul connections
•
TNT-SL-UOC3LF-C—with an optical fiber interface, for long-haul connections
Status indicators
The OC3-ATM2 slot cards provide status indicators described in Table B-17. All status lights
except LA are illuminated upon power-up or reset and remained illuminated until the card
passes POST. If no status lights are illuminated, the OC3 interface is either disabled or is
receiving an Alarm Indication signal (AIS) or Idle signal.
Interfaces per card
One unchannelized DS3 port with integrated CSU/DSU.
Maximum of four cards per chassis.
