Mitel SX-200 DIGITAL Pabx General Description Manual

							Traffic Measurement 
Peg: Represents the total number of times that the 
DTMF receivers were accessed during the mea- 
surement period. 
Usage: Represents the total usage (Erlangs or CCS) for 
the DTMF receivers during the measurement 
period. Does not include busied-out receivers 
(maximum = 6553.5 ccs). 
Busy Peg: Represents the number of times a call could not 
be allocated a DTMF receiver immediately due 
to busy conditions. 
Maximum in use/ 
Available: The scanned maximum count of the number of 
receivers in use during the period and the num- 
ber that are available for use. Does not include 
busied-out receivers. 
Channel Usage And Local Switching - records activity between Bays 
and whhin each Peripheral Bay 
Bay Number: Identifies Bay for which data is being accu- 
mulated. 
Channel Usage: Usage of channels available to the Bay. Does 
not include channels allocated for music or 
tones (maximum = 6553.5 ccs). 
Max Channel/ 
Available: The scanned maximum number of channels in 
use and the number available for use. Does not 
include channels allocated for music or tones. 
Local Switching Usage of peripheral bay local switching 
Usage: (maximum = 6553.5 ccs). 
Max Local Switching: The scanned maximum number of local switch- 
es found in a peripheral bay. 
Console - records activity of each console on the system 
Console Number: Directory number of the console. The console 
directory number is determined at the time of 
the report. If this console had been deleted, it 
will display ???? indicating that the directory 
number could not be determined. 
Usage: 
Call Waiting Usage: 
Calis Answered: Non-idle use of the console. The console is 
non-idle when it is using a channel. The con- 
sole is idle when it is ringing, using the applica- 
tion key, or using the select features key 
(maximum = 36 ccs). 
Usage of the Console queue when calls cannot 
be immediately answered (maximum = 655.35 
ccs). 
Calls answered using the console. Includes 
softkey and ANSWER key answers (maximum 
peg count = 65535). 
Page 2-4  
						

							Traffic Measurement 
Avg Waiting Time: Average waiting time for a call to the console 
to be answered. 
Hunt Groups - records activity of each hunt group 
Hunt Group Number: Programmed hunt group number. 
Peg: Number of accesses to hunt group, including 
busy attempts (maximum = 65535). 
Usage: Usage of all devices in the hunt group 
(maximum = 6553.5 ccs). 
Busy Peg: Number of times the hunt group was busy. 
Max in use/Available: Scanned maximum number of devices in the 
hunt group that were busy; busied-out devices 
are not included. 
Trunk Groups - records activity of each trunk group 
Trunk Group Number: Programmed trunk group number. 
Peg: Number of accesses to trunk group, including 
busy attempts (maximuE = 65535). 
Usage: Usage of all trunks in the trunk group making 
outgoing calls, measured in CCS or Erlangs 
(maximum = 6553.5 ccs). 
Busy Peg: Number of times the trunk group was busy 
(maximum = 255). 
Max in use/Available: Scanned maximum number of trunks in the 
trunk group that were busy; busied-out trunks 
are not included. The number of available trunks 
in a trunk group is determined at the time of 
the report and is not in the storage registers. 
Trunks - records activity of each trunk during the measurement period 
Trunk Number: List of all trunk numbers that were accessed. 
Peg in: Total number of times the trunk was seized by 
incoming calls on the trunk (maximum = 255). 
Usage In: Represents the usage (in Erlangs or CCS) for 
incoming calls on the trunk (maximum = 36 
ccs). 
Peg Out: Total number of times the trunk was seized by 
an outgoing call on the trunk (maximum = 255). 
Usage Out: Represents the usage (in Erlangs or CCS) for 
outgoing calls on the trunk (maximum = 36 ccs). 
Register Count Examples 
2.05 A call which lasts for 100 seconds has a value of 1 ccs 
(hundred-call-seconds). One Erlang equals 36 ccs (3600 call 
seconds). Usage is measured in lo-second units; for example, a usage 
Page 2-5  
						

							Traffic Measurement 
count of 128 (128 x 10 s) represents 1280 seconds of usage, equivalent 
to 12.8 ccs or 0.3556 Erlang (36 ccs equals 1 Erlang). The following 
example illustrates these “count” methods. 
Extension Originations Peg Count - Each time an idle extension goes 
off-hook, it causes the register to increment by one count. Since it is a 
measure of the number of calls originated by the extensions, it does 
not increment when a ringing extension goes off-hook to answer a 
call. For example, if this register has a value of 858, the number of call 
originations (or off-hook originations) during the period totalled 858. 
Trunk Group Usage - Each time the system scans the members of 
this trunk group, at 10 second intervals, it counts the number of 
members that are busy. A register value of 273 indicates that members 
were busy for 273 X 10 = 2730 seconds (27.3 ccs) during the measure- 
ment period. 
Power Failure 
2.06 If power fails to the system, the current traffic measurement 
will be lost, and the latest traffic report will also be lost if it had 
not been output. When power is restored, traffic measurements will 
restart, and continue until the end of the scheduled period. This pe- 
riod’s start time will be the time of the power-up.

3. TRAFFIC MEASUREMENT COMMANDS 
Maintenance Terminal and Console 
3.01 The maintenance terminal or console is used to enter the data 
required to start traffic measurements, print measurements, 
monitor status, or change traffic measurement parameters. Refer to 
Section MITLSI 08-093-35 l-NA, RS-232 Maintenance Termina! for 
instructions on using the terminal. At the maintenance terminal or 
console, select the MAINTENANCE application; from the MAINTENANCE 
main menu, select TRAFFIC MEAS (softkey 5).

Use the SET command to enter or change any traffic measurement 
parameters; use the prompts to change the required data and then exit 
from the TRAFFIC MEAS function. Once the START command is issued, 
the PERIOD and DURATION cannot be changed for the current traffic 
measurements. The AUTOPRINT, and CONDENSED parameters can be 
changed while it is running. At the beginning of each period of current 
traffic measurement, the pegs and the dynamic records are initialized. 
If a new trunk group was set up by CDE, it would not be included in 
the traffic report until the next period. The START command cannot be 
issued while traffic measurement is on; it must be STOPped and then 
Page 3-l

restarted. 
STOP Command - This command causes two softkeys to become 
active, and pressing either selects what is to be 
stopped. 
TRAFFRPT 
PRINT - stops the traffic measurement currently active. No 
report will be made of the incomplete collected data. 
- stops a printout being sent to the PRINTER port. 
Note: The STOP command will not stop an AUTOPRINT in progress; 
the AUTOPRINT command must be set to OFF between print- 
outs to stop printouts. 
SHOW STATUS Contains a summary report on the current traffic 
Command measurement parameters. 
STATUS : Activated/OFF 
DATA COLLECTION : Running/OFF 
START TIME : hh:mm 
DURATION : nn periods 
PERIOD : mm minutes 
UNITS : erlangs/ccs 
AUTOPRINT : ON/OFF 
CONDENSED : ON/OFF 
START TIME and DATA COLLECTION are not 
displayed if STATUS is OFF. 
DATA This indicates that data is currently being collected 
COLLECTION (if it is running). When it is OFF, either the daily start 
time has not been reached, or, it has finished the 
required number of periods since the start time; in 
either case, no data is currently being collected. 
PRINT This softkey command causes the latest traffic 
report held in the system to be immediately printed. 
READ This softkey command causes the latest traffic 
report in the system to be displayed on the 
maintenance terminal, where it may be read by the 
user. READ is only available at the Maintenance 
Terminal. If the Console softkey is pressed, the 
following message appears on the LCD display: 
QUIT This function is not available for this device. 
This softkey command allows the user to exit from 
Traffic Measurement mode at the console or 
terminal.

Connection Requirements, Local Printer 
4.02 Section MITL9108-093-200-NA details the installation of SX- 
200@’ DIGITAL PABX systems; also refer to Section MlTL9108- 
093-351-NA, RS-232 Maintenance Terminal, and reference System Set 
Commands which assign printers during installation and initial main- 
tenance programming. The Traffic Measurement data may be output to 
a printer, magnetic recording device, or the maintenance terminal. If 
required, a Data Demultiplexer may be used and the Traffic Measure- 
ment data directed to one output of it. 
4.03 When a local printer is used, it should be located as near as 
possible to the PABX, and connected to the PABX data port with 
a 25-conductor connectorized cable, not longer than 4.5 m (15 ft) in 
length.
