Figure 124 Translation Encapsulation Mode Configuring Virtual Circuits 153 DLCI FRR VCC A TM A TM Router with FRR IWF Translation RFC 1490 RFC 1483 DE-CLP / CLP-DE-DE to CLP / CLP to DE mapping. DE to CLP defines the value to which CLP will be set in outgoing ATM cells. CLP to DE mapping defines the value to which DE will be set from incoming ATM cells in outgoing Frame Relay frames. Direct-Mode 1 mapping; matches DE value to CLP value. When the serial port is in this mode, it does not translate between Frame Relay (NLPID) encapsulation, rather it send it straight through the ATM network, possibly onto a Frame Relay network or device. Always 0 -Mode 2 mapping, with the CLP field mapped to a constant value of 0. Mode 2 is an operational method for indicating data congestion to either the ATM or Frame Relay network. Mode 2 allows for translation between NLPID and LLC-SNAP encapsulation. It is used when connecting a Frame Relay device or network to a non-Frame Relay device or network. For example, if the PathBuilder S330/S310 is connecting a router/FRAD over an ATM network (public or private) and at the other site a router with an ATM OC3/STM-1 UNI is connected to the WAN network, typically the router OC3/STM-1 UNI does not support NLPID and requires mode 2 mapping so that the packet can be encapsulated to LLC-SNAP. Always 1-Mode 2 mapping, with the CLP field mapped to a constant value of 1. Mode 2 is an operational method for indicating data congestion to either the ATM or Frame Relay network. Mode 2 allows for translation between NLPID and LLC-SNAP encapsulation. It is used when connecting a Frame Relay device or network to a non-Frame Relay device or network. For example, if the PathBuilder S330/S310 is connecting a router/FRAD over an ATM network (public or private) and at the other site a router with an ATM OC3/STM-1 UNI is connected to the WAN network, typically the router OC3/STM-1 UNI does not support NLPID and requires mode 2 mapping so that the packet can be encapsulated to LLC-SNAP.

Translation Encapsulation Mode

DE-CLP / CLP-DE

—DE to CLP / CLP to DE mapping. DE to CLP deﬁnes the value to

which CLP will be set in outgoing ATM cells. CLP to DE mapping deﬁnes the value

to which DE will be set from incoming ATM cells in outgoing Frame Relay frames.

Direct

—Mode 1 mapping; matches DE value to CLP value. When the serial

port is in this mode, it does not translate between Frame Relay (NLPID)

encapsulation, rather it send it straight through the ATM network, possibly

onto a Frame Relay network or device.

Always 0

—Mode 2 mapping, with the CLP ﬁeld mapped to a constant value

of 0. Mode 2 is an operational method for indicating data congestion to either

the ATM or Frame Relay network. Mode 2 allows for translation between

NLPID and LLC-SNAP encapsulation. It is used when connecting a Frame Relay

device or network to a non-Frame Relay device or network. For example, if the

PathBuilder S330/S310 is connecting a router/FRAD over an ATM network

(public or private) and at the other site a router with an ATM OC3/STM-1 UNI is

connected to the WAN network, typically the router OC3/STM-1 UNI does not

support NLPID and requires mode 2 mapping so that the packet can be

encapsulated to LLC-SNAP.

Always 1

—Mode 2 mapping, with the CLP ﬁeld mapped to a constant value

of 1. Mode 2 is an operational method for indicating data congestion to either

the ATM or Frame Relay network. Mode 2 allows for translation between

NLPID and LLC-SNAP encapsulation. It is used when connecting a Frame Relay

device or network to a non-Frame Relay device or network. For example, if the

PathBuilder S330/S310 is connecting a router/FRAD over an ATM network

(public or private) and at the other site a router with an ATM OC3/STM-1 UNI is

connected to the WAN network, typically the router OC3/STM-1 UNI does not
