Cisco ASR 1000 Series Software Configuration Guide

PurposeCommand or Action
(Optional) Specifies the T1 framing type using the framing command.Router(config-controller)# t1
t1-number framing {esf | sf [hdlc-idle
{0x7e | 0xff}] [mode {j1}]}
Step 4
• sf—Specifies Super Frame as the T1 frame type.
Example:
If you select sf framing, you should consider disabling yellow alarm
detection because the yellow alarm can be incorrectly detected with sf
framing.
Note
• esf—Specifies Extended Super Frame as the T1 frame type. This is the default.
• hdlc-idle—Allows you to set the idle pattern for the T1 interface to either
0x7e (the default) or 0xff.
• mode j1—(Optional) Specifies the JT-G704 Japanese frame type.
(Optional) Specifies the T1 clock source.Router(config-controller)# t1
channel-number clock source
{internal | line}
Step 5
• internal—Specifies that the internal clock source is used. This is the default.
• line—Specifies that the network clock source is used.
After a T1 channel is configured, it appears to the Cisco IOS software as a serial
interface; therefore, all the configuration commands for a serial interface are
Configure the serial interfaces.
Step 6
available. However, not all commands are applicable to the T1 interface. All
encapsulation formats, such as PPP, HDLC, and Frame Relay are applicable to the
configured T1. Encapsulation can be set via the serial interface configuration
commands.
For detailed interface configuration information, see the Cisco IOS Interface
Configuration Guide for your Cisco IOS software release.
Verifying T3 Controller Configuration
Use the show controllers command to verify the controller configuration:
Router# show controller t3 2/0/0
T3 2/0/0 is up.
Hardware is SPA-2XCT3/DS0
IO FPGA version: 2.7, HDLC Framer version: 0
T3/T1 Framer(1) version: 2
SUBRATE FPGA version: 1.4
HDLC controller available FIFO buffers 4084
Applique type is Channelized T3/T1
No alarms detected.
MDL transmission is disabled
FEAC code received: No code is being received
Framing is C-BIT Parity, Line Code is B3ZS, Cablelength is 224
Clock Source is Internal
Equipment customer loopback
Data in current interval (726 seconds elapsed):
0 Line Code Violations, 0 P-bit Coding Violation
0 C-bit Coding Violation, 0 P-bit Err Secs
