| Description | The value of this object is used for setting the
channel type of a frame relay connection. If set
with values frSIW-transparent(2) and frSIW-translate(3),
all PVC data is subject to service interworking translation
and mapping in both Frame Relay-to-ATM and ATM-to-Frame relay
directions.
The possible values are :
frNIW(1) : Frame-Relay-to ATM Network
Interworking(NIW-unicast).
The traffic crosses the network as
ATM Cells.
frSIW-transparent(2): Service InterWorking with out any
SDU translation. In transparent mode,
the service module does not translate.
frSIW-translate(3) : Service InterWorking with SDU translation.
In translation mode, service module
translates protocol between the FR NLPID
encapsulation(RFC 1490) and ATM LCC
encapsulation(RFC 1483). Translation mode
support includes address resolution by
transforming address resolution protocol
(ARP, RFC 826) and inverse ARP(RFC 1293)
between the frame relay and ATM Formats.
frFUNI(4) : Frame based UNI: mode-1a which is ALL5.
frForward(5) : frame forwarding. Frame forwarding operates
same as standard frame relay except:
* 2 byte Q.922 header is not assumed
or interpreted.
* All frames received are mapped to a
specific connection if it exists. Otherwise
the frames are dropped.
* No DE/CLP or FECN/EFCI mapping is performed.
* 'llegal Header count' and 'invalid DLCI'
statistics are not kept/applicable.
frNIWReplace(6) : Frame Relay network interworking
with DLCI in FR-SSCS(Frame Relay Specific
Convergence Sublayer)PDU always
set to 1022. |
