Start DN
This is the first directory number (DN) in the DN range on the system. This number is
specified during system setup (Quick Start Wizard). Changing this number causes the
system to perform a cold boot and all telephony programming would be lost. This number
is assigned by default to DS30 02 first port. The Start DN defaults for a number of
settings, such as Prime line, Control telephone, and Auxiliary ringer (ringing groups).
startup programming
When a Business Communications Manager system is first installed and powered up, you
must perform Startup programming before you program other features. Startup initializes
the system programming to defaults. Use the Quick Start Wizard to perform this process.
static IP address
A static IP address, or fixed IP address, is an IP address that is permanently assigned to a
device on a network. The device retains the same IP address every time it connects to the
network and is known to other devices on the network by that IP address.
station auxiliary power supply
See SAPS.
station media bay module
A computer module which provides access to telephone lines within the Business
Communications Manager system. The 16-port digital station media bay module
(DSM 16+) connects a maximum of 16 digital telephone telephones to the system. The
32-port digital station media bay module (DSM32+) connects a maximum of 32 digital
telephone sets to the system. The Analog Station Media Bay Module (ASM8/GASM)
connects a maximum of eight analog telephony devices to the system. The Unified
Manager displays these lines as DN numbers. On systems running BCM 3.0 and newer
software, DS30 bus 02 to 05 default to double density, which means that each of these
DS30 buses can support up to 32 telephones. Legacy station modules can only support the
first 16 DNs on each bus. The DSM16+ (two per bus), the DSM32+ (one per bus) can
support the full 32 DNs. As well, the ASM8/GASM can be configured on all four offsets,
instead of just two. DS30 bus 06 and 07 default to single density, allowing them to support
legacy Companion equipment. However, the system can be configured to Full Double
Density (FDD), which means that these two bus blocks would also support 32 DNs, but
would not longer support Companion.
station set test
A series of diagnostic tests for these components of a telephone: display, buttons, handset,
speaker, and power.
subnet mask
A value used to route packets on TCP/IP networks. When the IP layer has to deliver a
packet through an interface, it uses the destination address contained in the packet,
together with the subnet mask of the interface to select an interface, and the next hop in
that subnet.
