Purpose
• t3—STS-1 carries an unchannelized (clear channel) T3.
• vt-15—A STS-1 is divided into seven Virtual Tributary Groups (VTG).
Configures the T1 on the VTG, where:
• vtg#—Specifies the VTG number. For SONET framing, values are 1 to
• Router(config-controller)# au-4 au-4# tug-3 tug-3#
•
• Router(config-controller)# au-3 au-3#
Purpose
Specifies SDH as the frame type.
Configures AUG mapping for SDH framing.
If the AUG mapping is configured to be AU-4, then the following muxing,
alignment, and mapping will be used:
TUG-3 <--> VC-4 <--> AU-4 <--> AUG
