BPX 8600-to-BPX 8600 Segment

For the middle segment, be sure to use the connection type as the local segments on the MGX 8230 node (CBR, VBR, ABR, or UBR). The parameters directly map from those specified at the connection endpoint.

Frame Service Module Features

This section describes the features available on each of the Frame Service Modules (FRSMs). The primary function of the FRSM is to convert between the Frame Relay formatted data and ATM/AAL5 cell-formatted data. For an individual connection, you can configure network interworking (NIW), service interworking (SIW), ATM-to-Frame Relay UNI (FUNI), or frame forwarding.

Note See the “Frame Relay Service Modules” section on page 2-20for more information on the features of the FRSM modules.

An FRSM converts the header format and translates the address for:

•Frame Relay port number and DLCI

•ATM-Frame UNI (FUNI) port number and frame address or frame forwarding port

•ATM virtual connection identifier (VPI/VCI)
