Configuration Tasks
Command Purpose
Step 1
Router(config)# controller sonet
slot/subslot/port
Selects the controller to configure and enters controller
configuration mode, where:
• slot/subslot/port—Specifies the location of the interface. See
the
“Specifying the Physical Address for Controller and
Interface Configuration” section on page 19-2.
Step 2
Router(config-controller)# sts-1
sts-1#
Specifies the SONET Synchronous Transport Signal (STS) level
and enters STS configuration mode, where:
• sts-1#—STS values are 1 to 3.
Step 3
Router(config-ctrlr-sts1)# mode
{ct3 | vt-15}
Specifies the mode of operation of an STS-1 path, where:
• ct3—A STS-1 carrying a DS31 signal is divided into 28 T1s
(Plesiochronous Digital Hierarchy [PDH])
• vt-15—A STS-1 is divided into seven Virtual Tributary
Groups (VTG). Each VTG is then divided into four VT1.5’s,
each carrying a T1.
Step 4
Router(config-ctrlr-sts1)# t1 t1#
clock source {internal | line}
Configures the clocking source, where:
• t1#—Number indicating the T1 channel.
• internal—Specifies that the internal clock source is used.
• line—Specifies that the network clock source is used. This is
the default.
Step 5
Router(config-ctrlr-sts1)# t1 t1#
fdl ansi
Enables the one-second transmission of the remote performance
reports using Facility Data Link (FDL), where:
• t1#—Number indicating the T1 channel.
• fdl ansi—Specifies FDL and ANSI T1.403 standard.
Without this command, FDL runs in ATT, the default mode. ATT
is the AT&T TR54016 standard.
Step 6
Router(config-ctrlr-sts1)# t1 t1#
framing {sf | esf}
Specifies the type of framing, where:
• t1#—Number indicating the T1 channel.
• sf— Specifies that Super Frame (SF) is used as the T1 framing
type.
• esf—Specifies that Extended Super Frame (ESF) is used as
the T1 framing type.
Step 7
Router(config-ctrlr-sts1)# t1 t1#
yellow {detection | generation}
Enables detection and generation of DS1 yellow alarms, where:
• detection—Detects yellow alarms.
• generation—Generates yellow alarms.
