PARAMETER

SSCS LMI

DE Bit Tagging

OPTION DEFINITION

Service Specific Convergence Sub-layer Link Management Interface used to establish a communications link between two frame relay endpoints. These are used to report connection problems to the transmitting endpoints.

Discard Eligible BIT Tagging is used to identify cells that are over and above the Committed Information Rate (CIR). Cells are tagged as “1” and may be discarded if system congestion occurs. Cells tagged as “0” are buffered and transmitted during system congestion. If selected, the connection will be treated as NRT-VBR3 (non-real time variable bit rate level 3). If not selected, the connection will be treated as NRT-VBR2

Translation

FR Discard Eligible markings will be carried over to the ATM Cell Loss Priority markings.

All FR frames will be tagged CLP=0.

All FR frames will be tagged CLP=1 and possibly discarded in the ATM stream in the event of system congestion.

Forward Explicit Congestion Notification marked FR cells will be mapped to the Explicit Forward Congestion Indicator markings in the ATM stream.

ATM Cell Loss Priority markings will be carried over to the FR Discard Eligible markings.

All FR frames will be tagged CLP=0.

All FR frames will be tagged CLP=1 and possibly discarded in the FR stream in the event of system congestion.

9.The Remote Connection Identifier (DLCI) is read only and reflects the DLCI number at the originating end of the connection. Under the Service Provider Profile heading are several blocks of information that will eventually be used for customer billing capabilities. These parameters are not yet selectable and are read only.

10.The lower section of the window displays either another FR section for FR-FR connections, or an ATM VC section for FR-ATM VC connections. For FR-FR connections, repeat steps 7 through 9 and select the Next button at the bottom of the window, then go to step 17, otherwise continue for FR-ATM VC connections.
