framing

See the following sections:

framing (E1, E3, and T1 Interfaces)

Syntax



framing (g704 | g704-no-crc4 | g.751 | g.832 | unframed
| sf | esf);

Hierarchy Level



[edit interfaces at-fpc/pic/port e3-options],
[edit interfaces e1-fpc/pic/port e1-options],
[edit interfaces t1-fpc/pic/port t1-options]

Release Information

Statement introduced before JUNOS Release 7.4.

Description

Configure the framing format.

Default

esf for T1 interfaces; g704 for E1 interfaces. There is no default value for E3 over ATM interfaces.

Options

esf—Extended superframe (ESF) mode for T1 interfaces.
g704—G.704 framing format for E1 interfaces.
g704-no-crc4—G.704 framing with no cyclic redundancy check 4 (CRC4) for E1 interfaces.
g.751—G.751 framing format for E3 over ATM interfaces.
g.832—G.832 framing format for E3 over ATM interfaces.
sf—Superframe (SF) mode for T1 interfaces.
unframed—Unframed mode for E1 interfaces.

Usage Guidelines

See Configuring E1 Framing, Configuring E3 and T3 Parameters on ATM Interfaces, and Configuring T1 Framing.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

framing (10-Gigabit Ethernet Interfaces)

Syntax



framing (lan-phy | wan-phy);

Hierarchy Level



[edit interfaces xe-fpc/pic/port]

Release Information

Statement introduced in JUNOS Release 8.0.

Description

For M120, M320, and T-series routers using the 10-Gigabit Ethernet IQ2 and IQ2-E PIC, configure the framing format.

Default

Operates in LAN PHY mode.

Options

lan-phy—10GBASE-R interface framing format that bypasses the WIS sublayer to directly stream block-encoded Ethernet frames on a 10-Gigabit Ethernet serial interface.
wan-phy—10GBASE-W interface framing format that allows 10-Gigabit Ethernet wide area links to use fiber-optic cables and SONET devices.

Usage Guidelines

See Configuring 10-Gigabit Ethernet Framing and Configuring SONET/SDH Physical Interface Properties.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

framing (SONET and SDH Interfaces)

Syntax



framing (sdh | sonet);

Hierarchy Level



[edit interfaces so-fpc/pic/port]

Release Information

Statement introduced in JUNOS Release 8.1.

Description

For the 4-port OC48 PIC with SFP installed and the 4-port OC192 PIC in T-series and M-series routing platforms, configure SONET or SDH framing on a per-port basis. This functionality allows you to mix SONET and SDH modes on interfaces on the same PIC.

Options

sdh—SDH framing.
sonet—SONET framing.

Usage Guidelines

See Configuring SONET/SDH Physical Interface Properties.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.
