Tables definition in mm_util.c #9

Closed photon303 closed 2 years ago

photon303 commented 2 years ago

Table definition in mm_util.c : "DLOG_MT_NPA_NXX_TABLE_15", // 0xa0 "DLOG_MT_NPA_NXX_TABLE_16", // 0xa1

It does not have the same table number in the millennium payphone wiki -> https://wiki.muc.ccc.de/millennium:start DLOG_MT_NPA_NXX_TABLE_15 is listed as 0x73 for mtr 1.x and 2.x(single compressed) or table 0x9a for mtr 2.x(double compressed LCD table) DLOG_MT_NPA_NXX_TABLE_16 is listed as 0x9b for mtr 2.x only (double compressed LCD table)

Who have the right info?

Based on the info I have, it might actually depend on the firmware version. If it's an international build, then the numbers change.

But I have DLOG_MT_NPA_NXX_TABLE_1 = 74 for the international build and DLOG_MT_NPA_NXX_TABLE_1 = 101 for the regular build. DLOG_MT_NPA_NXX_TABLE_15 is 0x73 in the regular build, but doesn't exist in the international build.

so, it would need more than 2 sets, at least 4 I imagine... or variables in the tables set defined upon detection of the version of the phone. Interesting... I would be curious to see the table list for the international version, is it a recent revision?

The information I have is pretty old and supposedly corresponds to version PBAXS03

It appears that different Millennium Terminal Releases (MTRs) changed the LCD table structure over time, from the original Uncompressed LCD tables in MTR <= 1.7, to Compressed LCD tables in 1.9, and double-compressed LCD tables in MTR 1.20 and 2.x. This commit: b4039992a09b3538f90c31991013770d8cf680c4 adds support for the three LCD table variants to mm_manager.
