￿Making an RJ-45 connector extension to BRI

As shown in Table 15, LT-S (NT side) and LT-T (User side) have different pin assignments in RJ-45. You can use the pin assignment tables (11–14) with Table 15 according to the func- tion of the BRI port. You should connect pins with the pins in Table 15 that have the same name.

Note: RJ-45 sockets come in different styles which look similar. However, pin numbers may be ter- minated in different places. Therefore, always check the pin numbers on your connectors.

BRI Related MMC Procedure

There are several MMCs related to BRI cards. Because some MMCs have dependencies on other MMCs, it could become cumbersome to do MMC programming correctly. You should, therefore, program these MMCs in a pre-defined order, as described in this section. Be sure to follow this order, or some of the MMC data will be lost.
