#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

Defines an FDL message for a DS1 signal, as defined in the ANSI T1.403 specification. This command applies to a DS1 over channelized SONET or SDH interface. Currently, FDL strings can only be configured locally. The no version restores the default value to the specified FDL message or to all FDL messages.

#### Options

- pathChannel—Number, in the range 1–2147483648, that identifies the path
- tributaryIdentifier—Specifier for the tributary in the format
  pathChannel { ds1 | e1 } pathPayload/tributaryGroup/tributaryNumber
  - pathPayload—Payload number for the path; value is 1 for SONET and in the range 1–3 for SDH
  - tributaryGroup—Number, in the range 1–7, that identifies the group within the path
  - tributaryNumber—Number of the tributary within the tributary group; the value is in the range 1–4 if the tributary type is vt15 or tu11 and in the range 1–3 if the tributary type is tu12
- eicValue—Equipment identification code; 1–10 characters; default value is the null value
- ficValue—Frame identification code; 1–10 characters; default value is the null value
- licValue—Line identification code; 1–10 characters; default value is the null value
- unitValue—Unit identification code; 1–6 characters; default value is the null value.
- pfiValue—Facility identification code to send in the FDL path message; 1–38 characters; default value is the null value
- portValue—Equipment port number to send in the FDL idle signal message; 1–38 characters; default value is the null value
