Before starting work, it is practical to read out chapters of the tutorial used as a help for the exercise. There wouldn't be control questions from these chapters, but it is practical to see them at home, because we can save time with it. These chapters are the following:
- Description of the PSTN/ISDN/VoIP network
- BCM 50 exchange - configuration database
- Definity exchange - configuration database
- AXD 305 MSS - configuration database
Answer the following questions shortly:
- Describe programming steps of the tool in BCM 50!
- What kind of lines were defined in BCM50?
- Describe steps of programming of an outgoing call in BCM 50!
- Describe steps of programming of an outgoing call in Definity!
The "measuring arrangement":
Detailed description can be found in tutorial.
Task: Trace routing of the outgoing and incoming calls:
Trace route calls between the phones of the measurement place from B3 (BCM50) to the D2 (Definty) exchange and vica versa with the help of the measuring arragement and configuration managements programs of exchanges (BCM 50, Definity, AXD AMS) in the telecomminucation test network! Main stations of the "study path" in case of call control (Originate, Destination, Routing):
- dialing plan of exchanges
- routing
- trunks
Main stations of the "study path" considering only the connection control (CE: PVC, Voice: MGW):
- port application assignment (CE?, Voice?)
- path (CE: PVC or Voice: MGW)
We will process it efficiently, if we visit stations of the study path only once, and then we record data related to both directions:
Record the result of tracking of the outgoing call into the following table:
(Tx - transmitted, Rx - Received, CPN - Called Party Number )

- 3. Study of services of answering calls
Motto: If somebody calls a firm, maybe he will bring a business! Don't let it pass!
That is why we should study carefully all the services of answering calls, that an exchange can provide to its users. If they are not programmed, then let us program them, and try these services! Record results of our test into the following table:
(Recommended classes of usage fields: individual device, group of devices, customer service, travel office, other...)Service sign Programmed Tested Recommended usage field Answer DN . . . Transfer . . . Forward . . . Park . . . SWCA . . . Pickup . . . Hunt . . . Voice Mail . . . - 4. Preparing the plan of services of a boss-secretary telephone pair and programming
We should realize this service with two digital telephones designated by the leader of measurement. Connect telephones to two unprogrammed ports of the exchange, designated by the leader of measureement.
After that we should prepare the plan of services and lines to be programmed for the function buttons, and then let us consult with the leader of measurement. After that, program the lines and services, and test them. Let us record result of our work into the following table:Dont't forget, that sequence of programming of devices is fixed!
Device for the boss:
#FB ---Function--- Test #FB ---Function--- Test 1 . . 5 . . 2 . . 6 . . 3 . . 7 . . 4 . . 8 . . #FB ---Function--- Test #FB ---Function--- Test 9 . . 17 . . 10 . . 18 . . 11 . . 19 . . 12 . . 20 . . 13 . . 21 . . 14 . . 22 . . 15 . . 23 . . 16 . . 24 . . Device for the secretary:

Facultative measuring tasks:
- Correction of a trunk programming error
Leader of measurement impairs one of parameters in the table recording result of tracking. Our tasks is to find the incorrect parameter and correct it with the help of devices used at the field-work.
