Configuring ATM for the Network Interface (9783, 9788)

Select ATM from the Network menu to display or change ATM option settings (see Table 4-12, Network ATM Options).

Main Menu Configuration Network ATM

Table 4-12. NetworkATM Options→→

Cell Payload Scrambling

Possible Settings: Enable, Disable

Default Setting:

9783 – If DSLAM Type is set to Paradyne: Enable

9783 – If DSLAM Type is set to a non-Paradyne DSLAM: Disable

9788: Enable

Specifies whether the 48-byte information field of ATM cells is scrambled/descrambled per ANSI T1.646 on this ATM link.

NOTE: For the 9783 CSU/DSU, the default setting is changed based upon the DSLAM

Type setting. See DSLAM Type (9783) on page 4-4for more information.

Enable – Activates scrambling/descrambling of transmitted or received ATM cells.

Disable – No scrambling/descrambling is performed.

Cell Delineation Error Event Threshold

Possible Settings: 1 – 1000

Default Setting: 10

Specifies the number of OCD (Out of Cell Delineation) events that must occur in a one-minute interval for an LCD (Loss of Cell Delineation) alarm to be declared.

1 – 1000 – Specifies the LCD alarm threshold.

FRF.8 Encapsulation Mode

Possible Settings: Translational, Transparent

Default Setting: Transparent

Specifies the type of FRF.8 upper-layer protocol encapsulation used on the link for each pair of interoperable Frame Relay and ATM PVCs.

Translational – Encapsulated data is translated (RFC 1490 to RFC 1483). FrameSaver multiplexing and SLV communications are not supported in this mode.

Transparent – Encapsulated data is forwarded without being translated.

ILMI

Possible Settings: Enable, Disable

Default Setting: Enable

Specifies the state of the Integrated Local Management Interface (ILMI). ILMI can be used in support of hybrid management, allowing access to the endpoint from a DSL provider’s Network Operation Center using the same management PVC that is used to manage the

DSLAM.

Enable – The ILMI channel is enabled. SNMP traffic, embedded in the ATM cells, is supported.

Disable – The ILMI channel is disabled.
