Syntax
t3 t3-number set mdl { data { eic string | fic string | gen-no string | lic string | pfi string | port-no string
| unit string } | detect | generate { idle-signal | path | test-signal } }
undo t3 t3-number set mdl [ data [ eic | fic | gen-no | lic | pfi | port-no | unit ] | detect | generate
[ idle-signal | path | test-signal ] ]
Default
The equipment ID and frame ID are line.
Views
CPOS interface view
Default command level
2: System level
Parameters
t3-number: Specifies the number of a T3 channel on the current CPOS interface, in the range of 1 to 3.
detect: Enables periodical maintenance data link (MDL) message detection on the specified T3 channel.
data: Sets MDL message parameters. Among these parameters, eic, lic, fic, and unit are parameters
common to the three types of MDL messages, while pfi, port-no, and gen-no are proprietary parameters
of path messages, idle signal messages, and test signal messages, respectively. Each of these
parameters is user-configurable and has its own length restriction.
eic string: Specify the equipment ID, a string of 1 to 10 characters. fic string: Specify the frame ID, a string
of 1 to 10 characters. gen-no string: Specify the generator number string sent in MDL test signal
messages. This string is of 1 to 38 characters and defaults to line.
lic string: Specify the location ID, a string of 1 to 11 characters. The location ID is line by default.
pfi string: Specify the facility ID sent in MDL path messages. This string is of 1 to 38 characters and
defaults to line.
port-no string: Specify the port number string sent in MDL idle signal messages. This string is of 1 to 38
characters and defaults to line.
unit string: Specify the unit ID, a string of 1 to 6 characters. This string is line by default.
generate: Transmits the MDL messages specified by the data keyword periodically. MDL path messages,
MDL idle signal messages, and MDL test signal messages can be sent simultaneously.
Usage guidelines
Use the undo t3 set mdl data { eic | lic | fic | unit | pfi | port-no | gen-no } command to restore the
default of a particular MDL message parameter.
MDL is a channel formed by using the three C-bits in the fifth subframe in C-bit framing. According to
ANSI T1.107a, it is used to transmit three types of maintenance messages, path, idle signal, and test
signal, and its data framing format is LAPD.
The output of the display controller cpos t3 command shows the receive/transmit status of the MDL link.
At startup of your device, periodical MDL message detection and sending are disabled on T3 channels,
and the default MDL message parameters apply.
Examples
# Enable MDL message detection on T3 channel 1 of CPOS 2/0/0.
