Nortel Networks BCM 1000 manual 64, Explaining double density, 64, Setting offsets

14Chapter 2 Documentation updates for BCM 4.0

•Element Manager access is also supported through a Citrix server

For information on downloading and installing Element Manager, refer to “Using Element Manager to set the basic parameters” on page 45.

Page 64, Explaining double density

The paragraph at the top of page 64 should be deleted, since Companion is not supported and PDD is not required.

Default BCM 3.0 and newer systems are configured as Partial Double Density (PDD) systems, in that they maintain DS30 06 and 07 in the original configuration of 16 DNs per bus. This accommodates those systems which use Companion. The system can be set to Full Double Density (FDD) at system startup or once the system is setup. When the system is set to FDD, DS30 06 and 07 allow access to the second set of DNs, and they are no longer available for Companion operation.

Page 64, Setting offsets

The following paragraph should be changed as follows:

For station modules, each bus supports 16 telephones or telephony devices for station modules that support single density, or which are set to single density in the case of the DSM16+ and DSM32+, or on DS30 06 and 07 if the system remains set to Partial Double Density (PDD). On each bus that supports double density, DSM16+ and DSM32+ modules set to double density have access to eight telephones per offset, for a total of 32 telephones per DS30 bus if the offsets are fully loaded.

Page 69, Environment checklist

The fourth bullet should be replaced with the following:

•within the temperature ranges of 0°C and 40°C (32°F and 104°F)

Page 70, Electrical requirements

The second bullet should be replaced with the following:

•The supplied power must be 100/240 V AC, 50/60 Hz, and 10 A minimum service with a third-wire safety ground. The third-wire safety ground provides shock protection and prevents electromagnetic interference.

Figure 38 should be deleted.
