Cisco ASR 1000 Series Software Configuration Guide

PurposeCommand or Action
• 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.
Configures the clocking source, where:
Router(config-ctrlr-sts1)# t1 t1# clock
source {internal | line}
Step 4
• t1#—Number indicating the T1 channel.
Example:
• internal—Specifies that the internal clock source is used.
• line—Specifies that the network clock source is used. This is the default.
Enables the one-second transmission of the remote performance reports using
Facility Data Link (FDL), where:
Router(config-ctrlr-sts1)# t1 t1# fdl
ansi
Step 5
• 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.
Specifies the type of framing, where:Router(config-ctrlr-sts1)# t1 t1#
framing {sf | esf}
Step 6
• 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.
Enables detection and generation of DS1 yellow alarms, where:
Router(config-ctrlr-sts1)# t1 t1# yellow
{detection | generation}
Step 7
• detection—Detects yellow alarms.
• generation—Generates yellow alarms.
Configures a T1 or E1 interface, where:
Router(config-ctrlr-sts1)# t1 t1#
channel-group channel-group#
Step 8
• t1#—Number indicating the T1 channel.
timeslots list-of-timeslots speed [56 |
64]
• channel-group#—Specifies the channel-group number, from 0 to 23.
• list-of-timeslots—Specifies one or more time slots.
• speed [56 | 64]—(Optional) Specifies the line speed in kilobits per second.
Valid values are 56 and 64.
Enables specific t1 channels to loopback, where:
Router(config-ctrlr-sts1)# t1 t1#
loopback [local | network {line |
Step 9
• t1#—Number indicating the T1 channel.
payload} | remote {line {fdl {ansi |
bellcore} | inband} | payload [fdl]
[ansi]}]
• local loopback—(Optional) Loops data from the transmit path to the receive
path.
