load.
One LEC per ELAN is recommended.

ATM Troubleshooting Tips
The ATM uplink module must be inserted into the lower PCI slot only.
A multimode fiber (MMF) cable is required for use with the 155 Mbps ATM
uplink OC-3 module.
Bind LANE, PTOP, and Trunking services via the port service
command.
Enable ILMI for LANE and signaling.
Employ an external router for communication between logically separate
ELANs for CIP.
Every ELAN must have one unique LES/BUS pair for LANE.
To join a specific ELAN, an ELAN name must be defined.
Ensure the same UNI signaling version is used between the ATM edge
devices and the ATM switch.
When manually entering the ATM address of the switch, omit the AFI prefix
(Ox).
Valid Trunk Indexes range from 0 through 15.
A VCI value is required when configuring PVC connections. Valid VCI
values range from 32 to 1023 (0-31 are reserved by the ATM Forum).
