the BCM system.
DSM16(+): supports 16 digital telephones through one RJ-21 connector.
DSM32(+): supports 32 digital telephones through two RJ-21 connectors.
Analog Station Media Modules
The analog station media bay modules (ASM, ASM8, ASM8+, and GASM8)
can connect to a maximum of eight analog telecommunication devices. These
devices are standard analog telephones, cordless telephones, fax machines,
answering machines, or modems.
In addition to ASM8 features, the ASM8+ and GASM8 offer the following
features:
 Visual Message Waiting Indicator (VMWI) — LED indicates that a
message is waiting.
 Disconnect supervision (Open Switch Interval [OSI] as per EIA/TIA
464). Indicates
communication, that the connected device should release the call
 Caller ID — provides the name, phone number, and other information
about the caller to the end user telephone at the start of the call.
 Firmware downloading capability — allows the system to upgrade the
ASM8+ and GASM8 firmware.
 Enhanced ringing capability — ASM8+ and GASM8 provide a ringing
voltage of 2 REN/65 V rms per port.
 Calling line identification (CLID)
 The GASM8 is designated as an ONS (on-premise station) port.
