allows the user to observe message acceptance or rejection, and to stop and restart message transmission
using the available
SEND:OFC
message options. The contents of the recent change APPTEXT file will cause
the 5ESS-2000 switch to update recent change Views 8.1 and 8.3 automatically. For example, the command
SEND:OFC;CHANNEL FIVE.SMTC, FILE REX.FIVE!
will send the APPTEXT recent change messages in
file ``rex.five'' to the central office over its second maintenance channel.
NOTE: To prevent loss of messages on the loffing channel, the SCC should use a recent change channel (if
available) or a second maintenance channel to execute the recent change file.
(4) REX Schedule Output: The program also generates a printout of the REX schedule that resembles RC/V
Views 8.1 and 8.3. If you elect not to use the recent change APPTEXT file that was generated by the
program, this printout simplifies the process of transcribing data from the schedule into the 5ESS-2000 switch
data base. It also reduces the likelihood of input errors.
12.10.2 PROGRAM LIMITATIONS
The program has the following limitations:
(1) Number Of Global Digital Service Unit (GDSU)/Transmission Test Facility (TTF) Responders
(TN304B):
The maximum number of SMs/SM-2000s concurrently executing ELS tests cannot exceed the
total number of TTF responders available for testing. The program will schedule as many SMs/SM-2000s as
possible, and then creates an ELS overflow list to identify the SMs/SM-2000s that could not be scheduled
successfully. In these instances, one alternative is to extend the duration of REX by starting it earlier or letting
it run longer. The other alternative is to equip the switch with an additional TTF responder board.
12.11 AUTOMATIC REX SCHEDULER
12.11.1 GENERAL
The automatic REX scheduler program is a switch-resident software tool that eliminates the work of determining an
optimal REX [and optionally, automatic line-insulation test (ALIT)] schedule and entering it manually through RC/V
views.
The tool reads the ODD to determine what equipment is operational in the given office and calculates a REX
schedule that provides the most complete coverage for the given equipment. This schedule is then printed to the
ROP. If the ``UPDATE'' option is used, the program also will automatically update the RC/V views (8.1 and 8.3) to
place the schedule into effect.
NOTE: Verify that RC/V view 8.3 exists before executing the Automatic REX Scheduler with the update (UPD)
option. If RC/V view 8.3 does not exist (as with a newly grown SM/SM-2000), it must be inserted or the
Automatic REX Scheduler will fail.
Whenever a CM REX schedule is printed, a companion warning message is also printed. The warning is intended to
alert the craft that when CM REX is running, AM REX,VFY:MHD or CMPR:MHD must not be running. The craft
should execute the CRONTAB UNIX command on the Lucent Technologies 3B20/3B21D computer to display these
schedules.
12.11.2 COMMAND SYNTAX
The basic command, entered at the MCC or trunk and line work station (TLWS), is:
EXC:SCHED[,ALL=]REX |
ALIT;
where the choices in brackets indicate the scheduling desired, whether REX, ALIT, or both (ALL). Details of
input and output messages to the ROP are shown in 235-600-700, Input Message Manual , and 235-600-750,
Output Message Manual
