Asm 8/Gasm8 Switch Settings; Table 20 Asm8 Settings For Upgraded 2.5 Systems And New 3.0 Systems - Nortel BCM1000 Installation And Maintenance Manual

ASM 8/GASM8 switch settings

For systems running software prior to BCM 3.0, only two ASM units can share a DS30 bus, using
offset 0, 1 or 2. BCM 3.0 software introduced the concept of double density, which allows you to
install an ASM8/GASM8 on all four offsets on DS30 02 to 05. DS30 06 and 07 remain in single
density mode for the default Partial Double Density (PDD) system. This means that only two
ASM8/GASM8 modules would be supported on these DS30 blocks unless the system is changed
to Full Double Density (FDD). GASM8 modules can also support firmware download on systems
running BCM 3.6 and newer software. Refer to
DN numbering sequence: A DS30 bus set to double density has a total of 32 lines available for
telephones. On systems upgraded from BCM 2.5/2.5.1, the first 16 lines on the bus do not number
consecutively with the second 16 lines on the bus. On systems that were new for BCM 3.0, the 32
lines on the bus do number consecutively.
Table 20 shows the switch settings for each DS30 bus and the dialing numbers (DNs) assigned to
each DS30 bus. The table shows settings for a system in FDD. For PDD systems, where DS30 06
and 07 are single density, only two modules can be installed on either bus.
