Configuration Tasks
Configuring DS1 (Channelized T3 mode)
To configure DS1, complete the following steps:
Step 6
Router(config-ctrlr-sts1)# t3 mdl
string {eic | fic | generator | lic |
pfi | port | unit} string
Configures maintenance data link (MDL) support parameters,
where:
• eic—Specifies equipment ID code.
• fic—Specifies frame ID code.
• generator—Specifies the generator number in MDL test
signal.
• lic—Specifies location ID code.
• pfi—Specifies the Path Facility Identification code in MDL
the path message.
• port— Specifies the port number in the MDL idle string
message.
• unit—Specifies unit identification code.
• string—Specifies user identifier for the chosen support
parameter.
The default is no mdl string.
Step 7
Router(config-ctrlr-sts1)# t3 mdl
transmit {path | idle-signal |
test-signal}
Configures MDL transmit parameters, where:
• path—Enables MDL path message transmission.
• idle-signal—Enables MDL idle signal message
transmission.
• test-signal—Enables MDL test-signal message
transmission.
The default is no mdl transmit.
Step 8
Router(config-ctrlr-sts1)# t3
equipment {customer | network}
loopback
Enables the port to honor remote loopback request. Equipment
network loopback disables this functionality.
Note Remote loopbacks are only available in c-bit framing
mode.
Step 9
Router(config-ctrlr-sts1)# t3 bert
pattern pattern interval 1-14400
Enables Bit Error Rate Testing (BERT), where:
• pattern—Specifies the length of the repeating BERT test
pattern. Allowed values are 0s, 1s, 2^15, 2^20, 2^23, and
alt-0-1.
• interval—Specifies the duration of the BERT test, in
minutes. The interval can be a value from 1 to 14400.
