Configuring resources — media bay modules
This chapter describes the Unified Manager headings that define and control the settings for the
media bay modules installed on your system.
This section contains information about:
• “Explaining the Media Bay Modules headings” on page 136
• “Defining trunk module types and settings” on page 142
• “Viewing station module information” on page 155
• “Internally-driven channels” on page 158
• “Working with the modules” on page 158
Media bay modules provide the Business Communications Manager with physical interfaces to
trunk (CO) lines and your system telephones, which are defined by directory number (DNs)
records. When media bay modules are first installed in your system you need to configure them
using the procedures described in this section. Media bay module DIP switch settings and
installation procedures are described in the
BCM1000 Installation and Maintenance Guide and the
BCM200/400 Installation and Maintenance Guide .
The Installation and Maintenance Guide also describes the concept of the 2/6 and 3/5 split, which
determines how many channels are available for media bay modules. When to choose to change
the DS30 split is discussed in the MSC section of this guide, refer to
Chapter 26, “Configuring the
MSC resources,” on page 613 .
The Installation and Maintenance Guide also describes the concept of partial double density
(PDD) and full double density (FDD). If your system is set to PDD (the default), and you have
installed a media bay module that supports double density, the system can support 32 lines on
whatever buses from 02 to 05 have the module installed. If your system was changed to FDD, the
Task:
Check settings for the media bay modules installed in the system.
Trunk modules:
• Confirm that the DIP switch setting matches the intended DS30 bus placement.
• Verify module type and programmed bus type settings under intended DS30 bus are correct for
the type of module installed
• Configure the module parameters of individual modules installed on each DS30 bus
Station modules:
• Confirm that the DIP switch setting matches the intended DS30 bus placement.
• Verify module type and programmed bus type settings under intended Bus # are correct for the
type of module installed
Note: Data and split-telephony/data module configuration are described in the section “Data and
split-line configuration” on page 161 .
