Release Information

Statement introduced before JUNOS Release 7.4.

Description

Configure the E3 or T3 interface to be compatible with the channel service unit (CSU) at the remote end of the line.

Default

If you omit this option, the full E3 or T3 rate is used.

Options

adtran—For T3 IQ interfaces only, configure compatibility with Adtran CSUs.

digital-link—Configure compatibility with Digital Link CSUs. If you include this option on an E3 interface, you must also disable payload scrambling.

kentrox—Configure compatibility with Kentrox CSUs. Kentrox subrate is valid for E3 IQ and T3 IQ interfaces only.

larscom—For T3 and T3 IQ interfaces only, configure compatibility with Larscom CSUs.

verilink—For T3 IQ and T3 IQE interfaces only, configure compatibility with Verilink CSUs

Note: Verilink configuration is not functional if an IQ interface is paired with an IQE interface.

subrate value—Subrate of the E3 or T3 line.

Range: For Kentrox CSUs on E3 IQ interfaces and T3 IQ interfaces the subrate value must match the value configured on the CSU. Each increment of the subrate value corresponds to a rate increment of about 0.5 Mbps.
