Cisco ASR 900 Series Configuration Guide

• Mode — Specifies the path operation mode.
• No — Negates a command or sets its defaults.
• Overhead — Configures SONET path overhead flags.
• Shutdown — Disables the SONET path.
• Threshold — Sets the path BER threshold values.
• vtg — Sets the VT-15 configuration.
Channelized SONET Frames
A channelized SONET interface is a composite of lower-speed STS streams. However, a channelized SONET
interface maintains the streams as independent frames with unique payload pointers. The frames are simply
multiplexed before transmission to increase the carrying capacity of the physical fiber. This process is similar
to multiplexing 24 digital signal level 0 channels into a DS1 or multiplexing 28 DS1 streams into a DS3.
SONET T1 Configuration Parameters
The following parameters affect SONET T1 configuration:
• BERT — Starts the BERT test.
• Clock — Specifies the clock source for T1 interface.
• Description — Specifies the description of the controller.
• Framing — Specifies the type of a framing on T1 interface.
• Loopback — Sets the T1 interface in the loopback mode.
• Shutdown — Disables the T1 interface.
SONET T3 Configuration Parameters
The following parameters affect SONET T3 configuration:
• Clock — Specifies the clock source for T3 link.
• Description — Specifies the description of the controller.
• Framing — Specifies the type of a framing on T3 interface.
• Loopback — Sets the T3 link in the loopback mode.
• Shutdown — Disables the T3 interface.
