Model 70 
The Model 70 PC-style desktop chassis sits conveniently on a surface and is ideal for small 
areas. This system consists of: 
l An Intel 486 DX66 CPU motherboard with 16 MB system memory, 200 watt power 
supply and a floppy disk drive. 
l Up to two hard disks (IDE interface), which stores system software, prompts, 
messages, mailbox account, and database information for a maximum of 55 hours of 
redundant storage. 
l Up to 7 full slots are available and a maximum 24 ports can be configured....

B. Model 1201 
The Model 1201 system is housed in an upright floor-standing PC-style tower. It consists of: 
l A 486SX33 Plug-in CPU and a backplane that supports up to 11 available slots, with ‘. 
a maximum of 32 ports. 
l Its hard disk interface is IDE and can support up to two hard disks for a maximum 
redundant speech storage capacity of 55 hours. 
l It also includes a floppy disk drive and an internal power supply. 
c. Model 120s 
l The Model 120s consists of a Pentium-100 Plug-in CPU and a...

D. The Model 640 System 
Centigram’s MESA design strategy has evolved to include individual assemblies for each 
component type. The result is the Model 640 (see Exhibit 13-5). The base Model 640 system 
consists of: 
l A storage assembly with one hard disk, one floppy drive 
l A CPU assembly that includes a backplane and up to 15 card slots 
l A power supply assembly with a single power supply. 
The power supply and storage assemblies have their own cooling systems. All assemblies are 
designed for...

.D.I Multihost Operations 
What happens when we take the architecture and expand it across multiple modules? When we 
build a large capacity system, or grow a 60-port system to a 240-port system, all modules operate 
as a single system with a single database, not a virtual single database created by networking 
separate systems together. QNX has built-in peer-to-peer networking, which allows the setup and 
control of tasks on any processor across the network. Whether the tasks are executing on the 
same...

Primary module intervention is required only when information is added to or deleted from a 
hard disk. This makes real-time processing possible even at the highest traffic levels, when all 
ports are active at the same time. 
Continuous System Operation (CSO) software provides a redundant “hot” standby of all primary 
module “master” programs. These programs will reside on the second module and be switched 
over as the “active” master programs for the remaining modules if the primary module fails. The...

processors in each module as functionally redundant system processors. There will be a 
STANDBY copy of all System Resourcetasks on a CPU in another module as a backup to the 
CPU of the ACTIVE Primary module. If the Primary module goes out of service, the Continuous 
System Operation software will activate the STANDBY system resource tasks for use by all 
other line card modules within 5 to 40 seconds. In conjunction with the I/O module, resources 
will also move the standby module.

with no downtime, and no impact on multimode system users. On a single-module system, there 
is a maximum of 15 minutes downtime to activate the new hard drive. 
13.3 Shared Resource Fax 
Beginning with Series 6, FaxMemo resources may be shared across multiple VoiceMemo ports. 
Customers do not need to dedicate a FaxMemo resource to a VoiceMemo port. Instead, a 
FaxMemo resource can be shared by assigning it to multiple VoiceMemo ports. If a call comes 
into one of the ports on the VoiceMemo line group...
