The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

T3 interface supports 4 ports. The channels on the T3 interface can be configured as either clear channel mode or channelized mode.
The following sections provide information about T3 interfaces.
The T3 interface supports two modes, clear channel mode and channelized mode.
The following are the benefits of T3 interfaces:
Higher bandwidth
Flexibility by channelization
To enable T3 controller:
enable
configure terminal
controller mediatype 0/4/12
mode t3
endWhen the clear channel T3 interface is used for the first time, the running configuration does not show the T3 controller. You can use the show platform command to check whether the chassis recognizes the T3 port and initializes the card correctly. After the port is configured for the slot, the respective controller appears in the running configuration and you can configure the clear channel T3 interface.
Perform this task to configure clear channel controller as T3.

configure terminal
controller t3 0/4/12

exit
 Note |
By default, the T3 controller is in C-Bit framing mode. To configure CEM, the framing mode must be set to unframed. |
Use the show controllers command to verify the controller configuration of clear channel T3 interface:
# show controllers t3 0/4/12

PE2#You can use the following methods to troubleshoot the T3 controllers on the chassis:
Bit error rate testing (BERT) is supported on T3 interfaces. You can run 16 BERTs at a time. The test can be either of the T1 or the T3 interface.
The interface contains on board BERT circuitry. With this, the interface software can send and detect a programmable pattern that is compliant with CCITT/ITU O.151, O.152, O.153 pseudo-random, and repetitive test patterns. BERTs allow you to test cables and signal problems in the field.
Use of a loopback somewhere in the link or network
Configuration of a remote testing equipment to transmit the same BERT test pattern at the same time
Both the total number of bits and the error bits received are available for analysis. You can select the testing period from 1 minute to 24 hours and you can also retrieve the error statistics anytime during the BERT test.
Line - supports BERT in TDM direction
System - supports BERT in PSN direction
Bit error rate testing (BERT) is supported on T3/E3 interfaces.
You can run 16 BERTs at a time.
The test can be either of the T1/E1 or the T3/E3 interface.

| Support for all 0s and 1s BERT Patterns |
Cisco IOS XE Bengaluru 17.4.1 |
Support for all 0s and 1s BERT patterns on T3 or E3 interfaces. |
The BERT patterns on the 48-port T3/E3 interface module are:
|
Keyword |
Description |
|---|---|
|
All 1s 1 |
Pseudo-random binary test pattern consisting of all 1’s that is used to test alternating line volt and repeaters. |
|
All 0s |
Pseudo-random binary test pattern consisting of all 0’s that is used for test line coding. |
|
2^15-1 O.151 |
Pseudo-random O.151 test pattern consisting of a maximum of 14 consecutive zeros and 15 consecutive ones. The length of this pattern is 32,768 bits. |
|
2^20-O.151 |
Pseudo-random O.151 test pattern consisting of a maximum of 19 consecutive zeros and 20 consecutive ones. The length of this pattern is 1,048,575 bits. |
|
2^20-O.153 |
Pseudo-random O.153 test pattern consisting of a maximum of 19 consecutive zeros and 20 consecutive ones. The length of this pattern is 1,048,575 bits. |
|
2^23-1 O.151 |
Pseudo-random 0.151 test pattern consisting of a maximum of 22 consecutive zeros and 23 consecutive ones. The length of this pattern is 8,388,607 bits. |
|
2^9 2 |
Pseudo-random binary test pattern consisting of a maximum of eight consecutive zeros and nine consecutive ones. The length of this pattern is 511 bits. |
|
2^11 3 |
Pseudo-random binary test pattern consisting of a maximum of ten consecutive zeros and eleven consecutive ones. The length of this pattern is 2048 bits. |
Note |
If All 1's BERT pattern is tested on the system side, then ensure that you need to start all 1's pattern from both sides of the end points. Configuring BERT on one side and loopback on other side of the end points is not supported. The router treats all 1's pattern as AIS alarm and BERT will not come in sync with the other side configuration of the end point. |
Before you configure BERT for clear channel T3 interfaces, ensure that controller and CEM are configured.

You can use the following loopback on the clear and channelized T3/T1 interfaces.
|
Loopback |
Description |
|---|---|
|
loopback local |
Loops the transmitting signal back to the receiver. |
|
loopback network line |
Loops the incoming signal back to the interface using the line loopback mode of the framer. The framer does not reclock or reframe the incoming data. All incoming data is received by the interface driver. |

Note |
To remove a loopback, use the no loopback command. |
Note |
Network payload configuration is not supported on SAToP. To configure loopback network payload when SAToP is configured, you need to remove the CEM configuration and then configure the loopback. |
The remote loopback configuration attempts to put the far-end T1 or T3 into a loopback.
The remote loopback setting loops back the far-end at line or payload, using IBOC (inband bit-orientated CDE) or the ESF loopback codes to communicate the request to the far-end.
E1 and E3 loopback remote are not supported until Cisco IOS XE Fuji 16.9.4 release. Starting from Cisco IOS XE Fuji 16.9.5 release, E1 and E3 loopback remote are supported.
IBOC loopcode configuration is not supported when CESoP or SATOP (framed or unframed) is configured.
ESF loopcode configuration is not supported when SAToP is configured.
