Router(config-if)# mdl [string {eic | fic |
generator | lic | pfi | port | unit} string}] |
[transmit {idle-signal | path | test-signal}]
Configures the Maintenance Data Link (MDL)
message.
• eic string—Specifies the Equipment
Identification Code (up to 10 characters),
which is a value used to describe a specific
piece of equipment according to ANSI
T1.107-1995.
• fic string—Specifies the Frame Identification
Code (up to 10 characters), which is a value
used to identify where the equipment is
located within a building at a given location
according to ANSI T1.107-1995.
• generator string—Specifies the Generator
number string sent in the MDL Test Signal
message; can be up to 38 characters.
• lic string—Specifies the Location
Identification Code (up to 11 characters),
which is a value used to describe a specific
location according to ANSI T1.107-1995.
• pfi string—Specifies the Path Facility
Identification Code sent in the MDL Path
message; can be up to 38 characters.
• port string—Specifies the port number string
sent in the MDL Idle Signal message; can be
up to 38 characters.
• unit string—Specifies the Unit Identification
Code (up to 6 characters), which is a value that
identifies the equipment location within a
subslot according to ANSI T1.107-1995.
• transmit idle-signal—Enables transmission
of the MDL Idle-Signal message. An MDL
Idle-Signal message, as defined by ANSI
T1.107, is distinguished from path and test
signal messages in that it contains a port
number as its final data element.
• transmit path—Enables transmission of the
MDL Path message. An MDL Path message,
as defined by ANSI T1.107, is distinguished
from idle and test signal messages in that it
contains a facility identification code as its
final data element.
• transmit test-signal—Enables transmission
of the MDL Test-Signal message. An MDL
Test-Signal message, as defined by ANSI
T1.107, is distinguished from path and idle
signal messages in that it contains a generator
number as its final data element.
