| 3 | The Pirelli DP-L10 is a tripleband GSM/Wifi VoIP dualmode phone, which was developed by Pirelli Broadband Solutions and manufactured by Foxconn. |
||
| 4 | |||
| 5 | It was branded and sold by quite a few operators: |
||
| 6 | |||
| 7 | * Pirelli DP-L10 |
||
| 8 | * Arcor Twintel DP-L10 |
||
| 9 | * Telekom TC-300 |
||
| 10 | * sipgate Pirelli Discus !DualPhone DP-L10 |

||
| 12 | * Cubic Mobile DP-L10 |
||
| 13 | * Tovo t450g |
||
| 14 | * Eurotef-M |
||
| 15 | |||
| 16 | The phones are still available as new at various places like eBay, Pollin or rebelsimcard.com. |

| 33 | 3 | steve-m | === PCB === |

| 35 | 3 | steve-m | The pcb is labelled with "T60N925", and the Foxconn internal project name seems to be "T60N925.00".[[BR]] |
| 36 | There are no schematics of this phone, however, steve-m has grinded down one of those boards, see the pictures of all layers [http://www.steve-m.de/pictures/pirelli_dpl10/ here]. |

| 45 | 6 | steve-m | === RF path === |
| 46 | |||
| 47 | Since this phone is a tripleband design, it uses 3 rx filters, connected to the respective Rita inputs: |
||
| 48 | |||
| 49 | * Epcos B7820 for GSM900 |
||
| 50 | * Epcos B7821 for DCS1800 |
||
| 51 | * Epcos B7851 for DCS1900 |
||
| 52 | |||
| 53 | Those are connected to an unknown "T 636 / 5475" antenna switch. The pinout of this switch however is identical with the Panasonic EZFL897TB11C. |
||
| 54 | The control voltage inputs of the switch are connected to the TSPACT outputs of the Calypso DBB through a Fairchild NC7NZ34 triple-buffer. |
||
| 55 | |||

||
| 57 | |||
| 58 | 3 | steve-m | === USB/Serial converter === |
| 59 | |||
| 60 | A nice feature of this phone is that it already has an integrated Silabs CP210x USB-UART, which is supported by Linux. Even faster, odd baudrates of the Calypso DBB are supported by this chip, including the maximum 812.500 baud. |
||
| 61 | Most of the phones seem to use USB vid:pid 0489:e003, which is mainline since Linux 2.6.36 (thus, older kernels need to be patched, the cp210x driver doesn't seem to take the vid/pid via modprobe parameters). |
||
| 62 | |||
| 63 | The DP-L10 has the CalypsoRomloader enabled. |
||

| 65 | 8 | steve-m | === JTAG === |
| 66 | |||
| 67 | All JTAG lines, as well as the second uart (UART_MODEM), go to the unpopulated connector next to the display connector. |
||
| 68 | |||
| 69 | 4 | steve-m | == State of support == |
| 70 | |||
| 71 | The code which adds support for the Pirelli DP-L10 can currently be found in the branch steve-m/testing, since it hasn't been merged to master yet. |
||
| 72 | However, this is mainly the RFFE-configuration so far, which handles the TSPACT and TSPEN wiring of the Time Serial Port. |
||
| 73 | |||
| 74 | So lots of drivers are missing, like for the Display, correct keypad layout etc. Maybe someone even wants to play with Wifi ;) |
||
| 75 | |||
| 76 | What works: |
||
| 77 | * RX/TX in GSM900 and DCS1800 (PCS1900 should work as well, at least regarding the rffe config) |
||
| 78 | * audio path |
||
| 79 | * SIM-reader |
||
| 80 | * keypad backlight |
