AMI Configuration Commands
Mode Indicates the mode of operation for this port. Can be
sonet or sdh .
Loopback Indicates the loopback mode on this port. Can be one
of the following:
none
,
line
, or
diagnostic
.
ClockSource For all network modules, network means that the
timing for this port is derived externally from the
incoming clock on this port.
Internal means that the
timing is derived from either the on-board crystal
oscillator or is derived from a specific port number
on a Series C network module that is defined by the
user. If set to a specific port number, the transmit
clock is derived from that port if available. If the port
source becomes unavailable, the on-board crystal
takes over as the transmit clock source.
Scrambling
On
indicates that payload scrambling is enabled on
this port.
Off
means that payload scrambling is dis-
abled on this port.
IdleCells Indicates the type of cells this port sends for filler
when the port is not sending data.
Idle cells set the
CLP bit = 1 and unassigned cells set the CLP bit = 0.
Please refer to page 57 of the ATM Forum 3.0 Specifi-
cation for more information. Idle = invalid cell pat-
tern and unassigned = unassigned. The default is
unassigned . In general, it is not necessary to change
this variable from the default setting.
