Multichannel STM-1 Port Adapter for the Cisco 7500 Series Router
Purpose
Enters SONET controller configuration mode.
Configures the framing mode of the to SDH.
Maps the AUG to AU-4 with the following
muxing/alignment/mapping:
C-12 <-->VC-12 <--> TU-12<--> TUG-2
<--> TUG-3 <--> VC-4 <--> AU-4 <--> AUG
Specifies the AU-4 and TUG-3 number to
configure:
au-4-number—a number in the range of
•
1 to N where N is the STM level (For the
PA-MC-STM-1 N is always 1.)
•
tug-3-number—a number in the range of
1 to 3.
Specifies the mode of operation of an AU-4.
c-12—The TUG-3 is divided into 21 TU-12s
•
each carrying an E1.
Creates a logical channel group on an E1 line.
tug-2-number—a number in the range of1 to 7
•
e1-number—a number in the range of 1 to 3
•
channel-group—defines a logical channel
•
group to be a channelized E1 line
channel-group-number—a number in the
•
range of 0 to 30
list-of-timeslots—a number in the range of
•
1 to 31 or a combination of subranges within
1 to 31 (Each subrange is a list of timeslots
that makes up the E1 line.)
Use the no form of this command to remove a
logical channel group.
The default is no channel group configured on an
E1 line.
Creates an unframed (clear channel) logical
channel group on an E1 line.
tug-2-number—a number in the range of
•
1 to 7
e1-number—a number in the range of 1 to 3

Returns to configuration mode.
