  1. TGP550 service seminar Information for repair

  2. Block Diagram TGP550 Base unit IP Communication check IC401(LAN IC),RJ45 jack Diagnostic of ICs RF check (same as DECT) MAC *MAC address *SW ver. info of IC 502 *Phonebook *ID code *Message numbers NOT replaceable *IP phone application program *Config. data

  3. Block Diagram Handset The handset circuit is same as ordinary DECT phone.

  4. IP communication check

  5. VoIP status display IP network access condition Terminal status Link status IP status Terminal data ……... [MENU]”#526” Useful for quick check when supporting staff visiting customer’s site on the phone L1 L2 L8

  6. LAN connection TGP IC504 (DSP) Terminal Status OK? IC401 (LAN IC) Terminal status Terminal Status OK? Using Web User Interface JK402 Terminal Status OK? PC Terminal Status OK? LAN port check Pow. (TGP) Pow. (Router) Try another LAN port Try another LAN cable Try another IP device Link indicator (Router)

  7. PC port check Check flow itself is almost same as LAN port check. No peer-to-peer mode check

  8. HUB check Basically to advise installer/PBX dealers who Ｗｉｌｌ visit customer site and check not only TGP units but also IP environment.

  9. Switching Hub check Repeater Hub check To support PBX installer/dealer. Refer to service manual for detail.

  10. Router Check Modem Check To support PBX installer/dealer. Refer to service manual for detail.

  11. Peer to Peer Test Mode Test IP Communication Using Direct Connection Set Up Preparation Preparation Customer’s Unit Reference Unit Test mode 1 Test mode 2 Phone number: #0456# Phone number: #0123# After this configuration, IP address become 192.168.0.240 Important Release Pier to Pier Test Mode by selecting “Normal mode” after log in to base unit.

  12. Peer to Peer Test Mode Connection Test Communication Test 1.<Making call test> Dial “#0456#” from test unit (Ref. unit will ring) . Answer the call with Ref. unit by SP-phone and check voice is OK. Press Off key of Ref. unit to hang up. 2.<Receiving call test> Dial “#0123#” from Ref. unit (test unit will ring) . Answer the call with test unit by SP-phone and check voice is OK. Press Off key of test unit to hang up. 1.Connect LAN port of both units using LAN cable. 2.Connect AC adaptor to both units to turn on the power. 3.Confirm status indicator of both units will be Green.

  13. Peer to Peer Test Mode How to release Peer to Peer test mode 1.<By Web user interface> 2.<By USB test mode> After setting up USB test mode connection, execute commands as below. 1.Command “ts” (to enter USB test mode) 2.Command “mode normal” (to return to normal mode) 3. Command “z” (to exit test mode) 1.Click “Maintenance” tab. 2.Select “Normal Mode” 3.Press “Save”.

  14. RF circuit check

  15. Test Mode (when there is no DECT tester) 4 1 2 3 3 2 1 4 Refer to service manual for details of USB test mode. Connection For TGP550 For TGP500

  16. Test Mode (when there is no DECT tester) To check quickly if Tx signal is there using spectrum analyzer Spectrum Analyzer 01 = CH1 To check Tx power. Need to connect spectrum analyzer at ANT2 01 = CH1 USB Test Mode - for Base Unit (Tx signal check) You can check RF by this USB test mode even if you do not have DECT tester.

  17. Test Mode (when there is no DECT tester) Ref. handset (signal source) Ref. handset (signal source) 01 = CH1 1.Check RSSI level of the target unit. 2.Check RSSI level of the Reference unit. USB USB Ref. unit PCB Target Base PCB USB Test Mode - for Base Unit (RSSI check ) You can check RF by this USB test mode even if you do not have DECT tester. Set both target unit and reference unit to test mode, then check and compare RSSI level. <NOTE> Be sure to make the distance between reference handset and base unit PCB same for fair comparison Compare and Judge

  18. Test Mode (when there is no DECT tester) Freq. counter USB USB Test Mode - for Base Unit (X’tal adjustment) Need to adjust X’tal frequency when IC504 or X’tal is replaced

  19. Test Mode (when there is no DECT tester) Spectrum Analyzer Target handset Ref. handset Test Mode for Handset (Tx-CW Mode) To check Tx signal level (comparison with reference unit) Compare Tx signal (radiation) level with Reference unit

  20. Test Mode (when there is no DECT tester) Spectrum Analyzer Target handset Ref. handset Test Mode for Handset (Test Link Mode) To check RSSI (comparison with reference unit) Compare RSSI value with Reference unit <NOTE> Be sure to make the distance between handsets and signal source for fair comparison.

  21. Test Mode (when there is no DECT tester) Freq. Counter Test Mode for Handset (Adjustment Mode) To adjust X’tal frequency and Batt. Low detection voltage Adjust so that the reading of freq. counter is 13.824MHz X’tal frequency adjustment Batt. Low detection voltage adjustment Set 2.34V precisely. Set 2.34V and 3.1V precisely. Charge current condition monitor adjustment Set 3.6V precisely. Wrong (non-rechargeable) battery detection voltage adjustment

  22. Diagnostics of ICs

  23. Important Point for Service Diagnostic of DSP, FLASH ROM, RAM (1) Basic Check Point IC501 IC502 IC503 MAC IC505 IC504 MAC Address is here! BGA How to Judge Defective IC Normal ALL : OK ALL : OK Program FLASH : OK RAM/DSP : OK Data FLASH : OK

  24. Important Point for Service Diagnostic DSP, FLASH ROM, RAM (2) Normal ALL OK IC502 (Prog. Flash) OK Base Unit PCB IC501 (Data flash) OK IC503(RAM) IC504(DSP) OK Data FLASH (IC501) is defective RAM (IC503) or DSP (IC504) is defective Program FLASH(IC502) is defective IC502 NG IC503 (RAM) or IC504 (DSP) NG IC502 OK IC503 OK Check IC503 soldering before replacing DSP . Replace Base PCB Replace Base PCB

  25. Useful information

  26. Useful Information Direct Command

  27. Important Point for Service Data Erase at Service – IP reset /Reset Web settings / Reset unit Only Web settings are reset to default. All settings are reset to factory default.

  28. Important Point for Service Data Erased at Service – IP reset /Reset Web settings / Reset unit By base unit key operation 【Menu】 【#730】  Select “Yes” 【Select】 *DHCP setting (set to “on”) *Setting of static IP addressing (cleared) *DNS setting for DHCP connection (cleared) *PHY settings (set to “automatic”) *Terminal number setting (set to “automatic”) “IP reset” Basic network settings By Web user interface Basic network settings Above basic items + settings by Web User Interface (see admin guide for detail.) + “Reset Web settings” Other parameters set by Web user interface programming Other data/information stored in the unit will remain. Page ?? in S/M May be revised Base unit 1.by USB test mode (Command “ts””h” ”z” ) 2.by Web user interface Following information will be cleared. <Base unit> *Redial *Registration data *Caller ID list *Phonebook *Phone number data in the unit <Handset> *Redial *Time setting *Phonebook *Registration data *Handset name “Reset unit” Reset all settings to factory preset Page ?? in S/M Handset Test mode by key operation (Press 3,7,# at the same time) Page ?? in S/M

  30. How to change MAC address label after replacing Base PCB MAC address and Serial Number are unique information for each PCB. Therefore, these need to be handled in three-piece. MAC address and Serial Number are unique information for each PCB. Therefore, these need to be handled in three-piece. Service parts ① ② ③ Be sure to replace both MAC label and Serial Number label to new ones after replacing PCB ① ② ③
