202 Converting a Small System to a Branch Office
• single-chassis Meridian 1 Option 11C Mini/Meridian 1 PBX 11C Chassis
with or without a chassis expander
• single-cabinet CS 1000M Cabinet
• single-cabinet CS 1000M Chassis with or without a chassis expander
Only single-cabinet and single-chassis systems (with or without a chassis
expander) can be converted. Multiple-cabinet and multiple-chassis Small
Systems must first be reduced to single cabinets or chassis.
To function as a Branch Office, the Small System must be equipped with
the following:
• a system controller card that meets the requirements for CS 1000
Release 5.0 software, specifically:
— NTDK20HA or newer Media Gateway Card (MGC) equipped with an
NTTK25xx Software Daughterboard.
— NTDK97AB Mini System Controller (MSC) card for chassis systems
only. The NTDK97AB MSC card supports a maximum of 2000
Corporate Directory entries.
• at least one Voice Gateway Media Card, running IP Line 4.5 software.
This card can be an 8- or 24-port Media Card (which occupies one slot)
or a 24-port ITG-P card (which occupies two slots).
• a Signaling Server
— If a Signaling Server is added to a previously CISPR Class B system
(previously used in some specific countries), the system is now
compliant to Class A, as noted in the front and back pages of this
document.

Conversion
A main office must exist before a Small System can be converted to a
Branch Office. The main office must be a CS 1000M or CS 1000E system
running CS 1000 Release 5.0 software.
