Nortel Networks BCM1000 Line and extension numbers for specific modules, DTM switch settings

Chapter 7 Setting media bay module DIP switches 91

Tip: Create a label with the DS30 bus and DIP switch settings, and stick it to the front of the module to provide ease of reference for maintenance activities.

Line and extension numbers for specific modules

The switch settings on the media bay module determine the line numbers and extension numbers the modules use. The tables in this section show the correspondence between DS30 bus numbers, switch settings, and the line/extension numbers for each type of module. The DS30 bus and switch settings correspond with Table 11 on page 88.

DTM switch settings

Although DTMs have more than 16 lines, they occupy only one DS30 bus per DTM.

Table 13 shows the switch settings for each DS30 bus, and the resulting line assignments.
