General information
This chapter provides an overview of the Option 11C system for first-time
installations. It covers general design and features as well providing unique
system information.
Page 10 of 408 Overview of the Option 11C
553-3021-210 Standard 7.00 January 2002
Design and architecture
The Option 11C is a small wall- or floor-mounted digital system which can
be configured as a system with up to five cabinets.
Up to four expansion cabinets can be connected to the main cabinet using
fiber optic cable or 100BaseT/F cable. The expansion cabinets can be located
up to 3 km (1.8 mi.) from the main cabinet. With the introduction of IP
connectivity, IP expansion cabinets can now be distributed over a campus
data network.
Call processing, serial ports and network traffic are handled by an MC68040
processor located on the Small System Controller (SSC) card in the main
cabinet. Performance is significantly increased in comparison with previous
Option 11 systems.
The Option 11C uses global software found in other members of the Meridian
1 family. It can be configured as a key system or as a Private Branch
Exchange (PBX).
Line cards and trunk cards used in the Option 11C are the same as those used
in other Meridian 1 systems, with the addition of some specially designed
cards used in the Option 11C system.
The Option 11C can be configured as a non-blocking system as it does not
need to be provisioned for speech paths or timeslots.
Easy to install and program
The system is shipped with a Software Daughterboard which is
pre-configured with system and customer data.
The Software Installation Program is automatically invoked during first-time
installation of the Option 11C system. This is a menu driven program which
installs the software and makes the Option 11C operational.
Model telephones
The user has a variety of pre-programmed model telephone layouts from
which to choose. Using telephone layouts or templates, technicians can
perform a few simple steps at installation to activate multiple telephones.
Overview of the Option 11C Page 11 of 408
Option 11C Planning and Installation Guide
Administration telephone
If the default model layouts for telephones and trunk routes are used, an
administrative telephone is all that is required to make adjustments to such
things as the numbering plan and access codes. A TTY input terminal is not
required for programming the Option 11C unless a custom layout is used.
The telephone used for administrative functions can be an M2616 or M2008
digital telephone. This phone can also double as a user’s working telephone.
Changing or removing pre-programmed data
If the pre-programmed data is not applicable to users at a particular site, the
data can be revised on-site with a TTY, or remotely over a modem
connection. If desired, the user can start with the minimal amount of data
required for initial software programming which is the configuration record.
This step must be performed while the user is in the Software Installation
Program.
Set-Based Administration
The Set-Based Administration feature simplifies system installation and
administration by enabling a telephone set to perform several administrative
and maintenance procedures. Examples such as changing data associated
with specific set-related features, or changing Calling Party Name Display on
a particular set, can be performed through the Set-Based Administration
feature.
For more information about Set-based Administration, refer to Set-Based
Administration (553-3001-303).
Multiple-terminal access
The Option 11C allows a total of five users access to log in, load, and execute
overlays simultaneously. For example, if you have expansion cabinets, users
can access the system through the Main or Expansion cabinets at the same
time.
Three Serial Data Interface (SDI) ports are provided on the Main cabinet’s
Small System Controller (SSC) card, while each expansion cabinet can be
accessed through three SDI ports on the SSC card of each IP Expansion
cabinet. One SDI port is available on each Expansion cabinet Fiber Receiver
card.
Page 12 of 408 Overview of the Option 11C
553-3021-210 Standard 7.00 January 2002
The advantage of multiple-terminal access is that it allows for more efficient
programming and maintenance of the Option 11C, especially when system
cabinets are located up to 3 km (1.8 MI) apart.
Meridian Mail
The specially designed Meridian Mail comes pre-configured with mailboxes
already setup for pre-programmed extensions. If the numbering plan is being
modified, then the mailboxes can be changed from any TTY used for
Option 11C administration.
Fully featured
The Option 11C may be configured with software applications such as
Automatic Call Distribution, Voice Mail, Automatic Route Selection,
Automatic Set Relocation, and Attendant Administration.
The Meridian Mail application comes equipped standard with features like
Voice Menus, Automated Attendant, and Hospitality Voice Services.
Meridian Mail Networking is available on advanced Meridian Mail systems.
There is a choice of software available offering everything from General
Business features to Advanced Applications. First-time installations are
performed from the Software Daughterboard that is initially provided with
the new system. Upgrades to new software releases are performed using a
Software Delivery card (PCMCIA card).
Option 11C with IP Connectivity
Option 11C IP Expansion provides IP interconnection between Option 11C
main and expansion cabinets. This IP interconnection enables:
• Increased Digital Trunking Capacity
• Survivable Expansion Cabinets
• Voice Distribution over Campus Data Network
The solution is applicable to Option 11C and Option 11C Mini systems.
Overview of the Option 11C Page 13 of 408
Option 11C Planning and Installation Guide
Increased Digital Trunking/SDI Capacity
This development provides increased networking capacity for the Option 11C
and Option 11C Mini systems. Digital trunks can now be supported in any IP
Expansion Cabinet or Mini main chassis, when connected via 100BaseT or
100BaseF. A total of 45 digital trunks could be supported on Option 11C, and
15 digital trunks supported on Mini.
The following CE cards can now be supported in IP expansion cabinets/mini
main chassis.
• 1.5MB DTI/PRI (NTAK09)
• 1.5MB TMDI (NTRB21)
• 2.0MB DTI (NTAK10)
• 2.0MB PRI (NTAK79)
• 2.0MB PRI (NTBK50)
• MISP (NTBK22)
• SDI DCH (NTAK02) (Only DCH is supported in IP Expansion Cabinets.
ESDI AML and TTY are not supported.)
This development also provides increased SDI/D-channel capacity. Three
SDI ports are provided with each IP Expansion Cabinet and D-Channel
capacity has been increased, such that a total of 16 D-channels are now
supported per cabinet.
Option 11C IP Expansion introduces two types of IP daughterboards:
• 100BaseT IP daughterboard
• 100BaseF IP daughterboard.
These boards are available in single and dual port versions. The dual port IP
daughterboard connects to the SSC of a Main cabinet and supports
connections to two expansion cabinets, each equipped with an SSC, via IP.
The single port IP daughterboard is used at the IP Expansion to provide
connectivity back to the Main.
The Option 11C SSC card can accommodate up to two single or dual port IP
daughterboards. The IP daughterboards can coexist with either the single port
or dual port fibre daughterboards.

553-3021-210 Standard 7.00 January 2002
Survivable IP Expansion Cabinets
IP Expansion Cabinets can be configured to be survivable in the event of a
link failure, or a catastrophic failure of the main cabinet.
Based on the system configuration, if IP connectivity to the main is lost or a
manual command is issued, an IP expansion cabinet can enter survival mode
in which it acts as a fully functional "Stand-alone" Option 11C.
The number of survivable expansion cabinets allowed on a specific system is
controlled via a new ISM parameter, "Survivability", which has a range of
0-4. The default value for this ISM parameter is zero.
Voice Distribution over Campus Data Network
The IP Connectivity of expansion cabinets enables a high capacity, cost
effective solution to distribute Option 11C and Mini cabinets over a high
performance data network.
Full feature functionality, and non blocking architecture is maintained when
Option 11C systems are distributed over high performance data networks.
This patented solution delivers the exceptional functionality and reliability of
Meridian 1 Option 11C, while delivering the benefits of voice/data
convergence.
Support of Option 11C Mini Cabinetry
This aspect of Option 11C IP Expansion allows the software functionality
described above to be supported on the Option 11C Mini platform as well as
the Option 11C platform.
A mix and match strategy allows a mixture of both Option 11C’s and Mini
chassis within the same system.
Package Requirements
IP Connectivity is packaged under package number 295. If the IP Expansion
package is restricted, IP connectivity between the Main and IP Expansions
will be disallowed, regardless of whether or not IP daughterboards are
connected to the Main. CE-Mux Expansion is not separately packaged, but is
dependent on package number 295.
