SECTION MITL91 OW911 O-096-450-NA
obtained is compared with the register value and is only en-
tered if its value exceeds that in the register. The register value
will thus reflect, at the end of the hourly period, the maximum
or peak value of usage, and not total usage.
Note:
A call which lasts for 100 seconds is said to have a value of 1
ccs (hundred-call-seconds). For example, a "usage count" to-
tal of 128 represents 1280 seconds of usage, equivalent to
12.8 ccs (36 ccs is equivalent to 1 Erlang).
Register Count Examples
2.07 The following examples respectively illustrate these "count"
methods. The register descriptions are abstracted from Table
2-l:
(a)
Register
002 (Extension Originations Peg Count). Each time an
idle extension goes off-hook, it causes the register to incre-
ment by one count. Thus it is a measure of the number of calls
originated by the extension. It does not increment when a
ringing extension goes off-hook Table 3-l as an example,
shows this register to have a value of 858; i.e., the call origina-
tions (or off-hook originations) during the period totalled 858.
(b)
Register
006 (Junctor Usage). At each scanning interval the c ,.
number of junctors in use is added to the value contained in
the register. At the end of the traffic hour, the register will thus
reflect the total usage of the junctors during the period. It
includes the use of junctors by the diagnostic, and thus will not
be zero even if the system handled no calls during the period.
Table 3-l shows an example value of 570; i.e., the occupancy
time for all junctors used during the period totalled 570 ccs
traffic units.
(c) Register
005 (Maximum Junctors). At each scanning interval the
number of junctors in use is determined and compared to the
number held by the active register. If the number is greater
than that held by the register, it replaces the held number. The
register will thus reflect the maximum of junctors which were
used at any one time during the traffic hour. The value will
include the two junctors used by the diagnostics. Even if the
system handled no calls, the register will contain a "2" (unless
the system was in the programming mode). The example in
Table 3-l indicates that during the period a peak or maximum
number of 22 junctors were in use at some particular instant.
Output Methods
2.08 The traffic measurement data can. be obtained in different ,':,;I
modes and formats, and output to a local or remote- terminal.

These are discussed in Part 3.
