Configuring the Interfaces
When the switch is powered on initially without any previous configuration data, the ATM
interfaces are automatically configured on the physical ports. ILMI and the physical card
type are used to automatically derive the ATM interface type, UNI version, maximum
virtual path identifier (VPI) and virtual channel identifier (VCI) bits, ATM interface side,
and ATM UNI type.
Default ATM Interface Configuration Without Autoconfiguration
If ILMI has been disabled or if the connecting end node does not support ILMI, the
following defaults are assigned to all CES T1 and CES E1 interfaces:
•
ATM interface type = UNI
•
UNI version = 3.0
•
Maximum VPI bits = 8
•
Maximum VCI bits = 14
•
ATM interface side = network
•
ATM UNI type = private
•
Loopback = no loop
•
Signaling mode = no signaling
•
Clock-source = network derived
•
Data format = clear channel
•
Timing = synchronous
•
Line build out = 0 to 110 feet
•
Cell delay variation = 2,000 microseconds
•
Channel associated signaling = false
•
Partial fill = 47
