RDI cells are received for 3 seconds, the router sets the logical interface status to up. You
do not need to configure anything to enable defect indication.
For ATM1 and ATM2 IQ interfaces with an ATM encapsulation, you can configure the
OAM F5 loopback cell threshold on VCs. This is the minimum number of consecutive
OAM F5 loopback cells received before a VC is declared up, or the minimum number of
consecutive OAM F5 loopback cells lost before a VC is declared down.
By default, when five consecutive OAM F5 loopback cells are received, the VC is considered
to be up, and when five consecutive cells are lost, the VC is considered to be down. To
modify these values, include the
oam-liveness {
up-count cells;
down-count cells;
}
For a list of hierarchy levels at which you can include this statement, see oam-liveness.
The cell count can be a value from 1 through 255.
Layer 2 cell-relay encapsulation supports the concatenation (aggregation) of multiple
ATM cells in a single encapsulated packet that is transmitted on a pseudowire. By default,
each packet contains one cell. For ATM interfaces with Layer 2 circuit cell-relay transport
mode configured, you can configure the time threshold (in microseconds) that the router
uses to concatenate ATM cells and transmit the cells in a single frame on the pseudowire.
To set the period for which the ATM cells must be collected to be bundled in a single
frame being transmitted on the pseudowire, include the

Based on this configuration, the router attempts to collect and concatenate ATM cells
in a single ATM cell relay-encapsulated packet and transmit the packet on a pseudowire
connection. When the router detects that the allotted time interval has expired, the router
forwards the packet even if it contains fewer than the specified maximum number of
aggregated cells per packet. The cell concatenation or bundling functionality is controlled
by the timeout value and the maximum number of cells to be concatenated.
To configure the period for which the ATM cells are aggregated and bundled before they
are transmitted in a single frame on a pseudowire connection:
Specify the number of microseconds for which the ATM cells must be bundled before
the timer expires and the cells are transmitted in a single frame.
