DESCRIPTION
Displays all IMA DTPVC settings for the
specified IMA slot, IMA group, or IMA
group with a channel.
Select the source of the clock which the
IMA should use for the E1 port(s) in the
selected IMA group.
Enables the specified IMA group.
Disables the specified IMA group.
Sets the number of ATM cells that can be
accepted in an IMA frame for the
specified IMA group. An IMA frame
contains one ICP cell and the number of
ATM cells you specify here.
Sets the parameters the IMA line card
uses to control the frame synchronization
mechanism in the specified IMA group.
Sets link members for the specified IMA
group.
Displays information about the specified
IMA group.
Sets:
• Symmetrical Configuration: Each E1
physical line has an upstream and a
downstream IMA links. Select this to
have an IMA link in this group be
allowed to transmit and receive data
only when both the downstream and
upstream links are active and
connected between the IMA devices.
• Symmetrical Operation: Both this IMA
line and the remote ADM device
should wait for the other end's "active
confirmation" before transmitting or
receiving data.
• Asymmetrical Operation: Both this
IMA line and the remote ADM device
do NOT need to wait for the other
end's "active confirmation" before
transmitting or receiving data.
symop = Symmetrical Configuration +
Symmetrical Operation
asymop = Symmetrical Configuration +
Asymmetrical Operation
Enter the maximum number of
milliseconds the IMA group can wait to
receive delayed data. If a delay exceeds
this setting, the IMA triggers a Loss of
Delay Synchronization alarm and
changes the state of the link to indicate a
line defect.
maxdifdelay: 25~300 ms
