This lesson is going to jump around a bit to cover some of the more subtle “gotchas” that are hiding in the BARS system.  It will cover the usage of Time Of Day Schedules (TODS), Account (Mobile Authorization) Codes, Equal Access restrictions, System Speed Call List (SSCL) interactions and some other goodies.

Time blocks all start at hh:00:00, hh:15:00, hh:30:00, or hh:45:00.  These blocks each end at hh:14:59,
hh:29:59, hh:44:59, and hh:59:59 respectively.  To move the hour of noon into schedule seven, the command would be:

TODS 7 12 00 12 59

The Extended Time Of Day schedule does the same thing for the days of the week.  It allows routing controls to be in effect for the period defined in the ETOD.

The routing control flag in the ESN activates the ability of the system to change a station’s NCOS on a temporary basis.  It is turned on by any of three possible methods.  The first is the <RTC> key on the attendant’s console.  The other two are TODS 7 and the ETOD.  The NMAP prompt in the ESN is where the redefinition is made.  The first number is the normal NCOS, the second is the NCOS the station user will have when routing controls are in effect.

NMAP 0 0
NMAP 1 1
NMAP 2 2
NMAP 3 7

Will change every station with an NCOS of 3 into an NCOS of 7 whenever TODS 7 is in effect, the ETOD is in effect, or the attendant’s <RTC> key is depressed.  NCOS 0, 1, and 2 stations will not be affected.

The final use of the TODS is in the Route List.  The flag TOD will allow each entry in the list to be allowed or denied depending on time of day.  A TOD X0 will block an entry from use during schedule 0.  A TOD 2 7 will make it available during schedules two and seven.  Notice that when it is used in the route block, schedule seven behaves just like all of the others.  This is not considered “routing control”, so this function is not affected by the state of the RTCL flag in the ESN.

First, the authcode data block must be programmed with the desired characteristics and a class code number (CLAS).  If the request was NEW then the AUTO feature can be used to generate up to 50,000 codes at one time for each class code. 

Second, the authcode entries data block (AUT) can then be used to assign, delete, or change a CODE and assign it a CLAS.  These commands require the use of a secure data password, default= “0000”.

Once the codes are in place and have been distributed to the intended users, they can be used to make any authorized call by that user on any phone in the system as though it was the user’s own.  They override everything including time of day restrictions.  The only exception to this is the Station Specific Authorization Code which can be used to limit use of authorization codes on single line phones.
