26 Patch Release Note

maintenance link allows a number of identification messages to be inserted in to the path overhead of the DS3 signal. These messages are in the form of text characters and allow the users at either end of the DS3 path to ensure that the correct DS3 signal has reached their equipment.

The DIRECTION parameter is used with the EIC, FAC, FIC, LIC or UNIT parameters to specify whether the text string is the text to transmit, or the text to expect in the received signal. If TRANSMIT is specified, the user is specifying a text to be transmitted out on the path. If RECEIVE is specified, the user is specifying the ASCII characters expected on the incoming path. If the DIRECTION parameter is present the TYPE parameter must also be present.

The EIC parameter specifies the Equipment Identification Code. This is 0 to 10 characters in length and describes the equipment at the near end, e.g. “RAPIER SW”. This parameter is only meaningful with the CMTCE parameter set to ON. With CMTCE set to OFF this parameter is ignored. The default pattern is “ignore”.

The FAC parameter specifies the FACility identification code. This is 0 to 38 characters in length and describes the DS3 path.

This data element is called FI in the ANSI specification, it is named FAC in this document to avoid confusion with the FIC parameter.

The FAC parameter is only valid if the TYPE parameter is set to PID. This parameter is only meaningful with the CMTCE parameter set to ON. With CMTCE set to OFF this parameter is ignored. The default pattern is “ignore”.

The FDET parameter specifies whether fast detection of AIS is enabled. If ON is specified, the AIS detection time is 2.23ms. If OFF is specified, the AIS detection time is 13.5ms. The default is ON.

The FIC parameter specifies the Frame Identification Code. This is 0 to 10 characters in length and describes where the equipment is located within a building, e.g. “FRAME 255”. This parameter is only meaningful with the CMTCE parameter set to ON. With CMTCE set to OFF this parameter is ignored. The default pattern is “ignore”.

The GENNO parameter specifies the test signal identification message. It is 0 to 38 characters in length and describes the signal generator that initiates a test message. This parameter is only valid if the TYPE parameter is set to ISIS. This parameter is only meaningful with the CMTCE parameter set to ON. With CMTCE set to OFF this parameter is ignored. The default pattern is “ignore”.

The LIC parameter specifies the Location Identifier Code. This is 0 to 11 characters in length and describes the specific location of the equipment, e.g. “BUILDING 1”. This parameter is only meaningful with the CMTCE parameter set to ON. With CMTCE set to OFF this parameter is ignored. The default pattern is “ignore”.

The PARAM15 parameter specifies the 15-minute counter threshold for all performance monitoring parameters (PES, PSES, SEF, UAS, LES, CES, CSES) between 1 and 900 seconds inclusive. If a trigger has been created, it will assert if the 24-hour count exceeds the value specified in PARAM15. The default is 900 seconds.
