Timer 102 and Timer 160 into Alcatel 4400

Product : Alcatel 4400.
Part Involved : Timer 260 and Timer 102.
Summary : Troubleshooting and adjust the values of timers.
Scenario : Add information related to how to set up these sets of timers
Company : National Institute of Cancer sickness of Peru (INEN).
Reference Date : April 2003.

Connect to PBX through telnet command by user mtcl, then proceed to follow next sequence : mgr / Translator / External Numbering Scheme / Numbering Descriptor / go down hierarchy / Consult Modify overview object

Timer 260 set up the maximum time of calling party and its relation scale vs value are 600 = 1 minute. This value will affect to overall outgoing call party restricted by "Telephone Facility category Id" from PBX.
Timer 102 set up a threshold time between when the calling party starts and the message of welcome starts. In this case 100 = 10 seconds. Taking as reference that values then the welcome message will be listen 10 seconds after started the calling party.

UpLink Rf's samples

Slow/fail connections dLink DI-624

Product : Wireless Access Point dLink.
Part Involved : DI-624 or DI-624+.
Summary : Recomendation to set up configuration of Access Point.
Scenario : Sometimes the device does not respond or is very slowly
Company : National Institute of Cancer sickness of Peru (INEN).
Reference Date : June 2006.

First the equipment was bought to supply the need of LAN data ports of structured cabling then it was very attractive the idea to replace that set of LAN data ports with wireless connections. One of the LAN data port of the equipment is connected to the floor distribution of the structured cabling while the SSID and additional parameters were set up, upto here there is no problems; I added a log trace of the activities did by the Access Point dLink DI-624 when is working connected to some type of LAN structure with 600 computers. Take as reference that the next log was collected some saturday afternoon -very low traffic data-

And after review log information I found the confirmation of the ip assigned to Access Point (192.168.0.11) and comparing between 16:14:25.533321 and 16:14:31.043850 (6 seconds) there are 4,298 request executed by Access point through port 1900 to access internet causing a excessive broadcast into LAN, forcing to the rest of devices connected to LAN to wait pass this 6 seconds, this cycle -set of request petitions through port 1900-is repeating constantly and I identify that this process slows the conecction of all the devices into LAN. The default values of this type of equipment considers enable this feature then proceed with the next window to disabled that option and in consequence enhanced the speed of the connections into LAN when you are using this type of equipment. UPNP functionality is associated with por 1900.

Part Involved : Engineer mode or testing mode.
Summary : Enable engineer mode or testing mode into mobile phone.
Scenario : Troubleshooting traffic channels of Cell sites .
Company : Motorola of Perú.
Reference Date : Nov 1997.

With the purpose to check if every sector -set of antennas-is throwing the right traffic channnel by the right place, the mobile phone is enabled into programming mode to trace through the display of the mobile phone if matched the traffic channel information. This method is used to test HandOff states and check RSSI values

After that, type #55#. It's going to appear on display of mobile phone every field only once at time -rows in the lines below-.To advance to next field press *. After the last field (16) to save and quit press 01# then the mobile phone wil be reset.
