Chapter 1 — Introducing the Option 11C
Mini
This chapter provides an overview of the Option 11C Mini system.
Option 11C Mini system description
The Option 11C Mini is a small communications system based on existing
Option 11C technology. The system provides full Meridian 1 feature
functionality. The Option 11C Mini uses X11 global software which other
Meridian 1 systems also use.
In an Option 11C Mini system, the Main Chassis can connect to a Chassis
Expander. This increases line size to 144 lines. Two copper cables connect
the Chassis Expander to the Main Chassis.
The Main Chassis and Chassis Expander each provide four Intelligent
Peripheral Equipment (IPE) card slots. These card slots support line cards,
trunk cards, and application cards used in other Meridian 1 systems. The
Option 11C Mini introduces a 48-port Digital Line Card (NTDK16). You
must insert the 48-port Digital Line Card in a dedicated slot (Slot 4) of the
Main Chassis. The Main Chassis also provides a dedicated slot (slot 0) for the
Mini System Controller (MSC) card.
A processor located on the Mini System Controller (MSC) card in the Main
Chassis handles call processing, serial ports, and network traffic. Call
processing on the MSC card is equivalent to that on the Option 11C Small
System Controller (SSC) card. Use the MSC card for configurations with up
to 144 lines.
The power supply for the Option 11C Mini is installed in the chassis before it
is sent to the customer site. You do not have to install the power supply during
system installation.
