Step 9
Router(config-ctrlr-au3)# [no] tug-2 tug-2-number e1
e1-number loopback [local | network {line | payload}]
Step 10
Router(config-ctrlr-au3)# [no] tug-2 tug-2-number e1
e1-number shutdown
Configuring an E1 Line Mapped to a TUG-3
Step 1
Router(config)# controller sonet 2/0/0
Step 2
Router(config-controller)# [no] aug mapping au-4
Step 3
Router(config-controller)# au-4 au-4-number tug-3
tug-3-number
Step 4
Router(config-ctrlr-tug3)# mode c-12
Step 5
Router(config-ctrlr-tug3)# tug-2 tug-2-number e1
e1-number framing {crc4 | no crc4}
Specifies a loopback for 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
•
local—Loops transmitted E1 output back to
•
the router via the internal E1 framer and loops
E1 output to the network via the internal E1
framer.
network—Loops E1 input back to the
•
network.
Shuts down 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
•
Enters SONET controller configuration mode.
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 a TUG-3.
c-12—The TUG-3 is divided into 21 TU-12s
•
each carrying an E1.
Specifies the type of framing used an by 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
•
crc4— 4-bit cyclic redundancy check
•
no crc4—basic framing
•
The default is CRC4.
