MG 1000B platform hardware description 31
MG 1000B Core, and the optional chassis expander performs the same
functionality as the MG 1000B Expander. Refer to "Converting a Small
System to a Branch Office" (page 201) for more information.
After conversion to an MG 1000B platform, the Small System cabinet or
chassis is referred to as an "MG 1000B Cabinet" or "MG 1000B Chassis",
as applicable. The optional chassis expander is referred to as the "MG
1000B Chassis Expander".
Throughout this document, the term "MG 1000B Core" can refer to an MG
1000B Cabinet or MG 1000B Chassis for a converted Small System, unless
otherwise indicated. Likewise, the term "MG 1000B Expander" can refer to
an MG 1000B Chassis Expander.
MG 1000B Core
The MG 1000B Core provides access to the local PSTN for users in the
Branch Office. It also provides support for digital telephones and analog
devices, such as fax machines and analog (500/2500-type) telephones
in the Branch Office.
Where required, the MG 1000B Core is connected by copper wire to the MG
1000B Expander for added capacity.
The MG 1000B Core must contain a CP-PM Call Server. The CP-PM Call
Server provides telephony services to elements at the Branch Office, such
as digital telephones, analog devices, digital trunks, and analog trunks.
It also provides call processing services to IP Phones when the phones
are registered to the MG 1000B Core (Local Mode). The MG 1000B Core
provides a dedicated slot (slot 0) for the CP PM. The software feature set on
the CP PM can differ from that of the Call Server at the main office.
The 10/100BaseT connection for the Embedded Local Area Network
(ELAN) and Telephony Local Area Network (TLAN) subnets, where the MG
1000B Core exists, is on the back of the MG 1000B Core.
Figure 3 "MG 1000B Core/MG 1000B Expander" (page 32) shows an MG
1000B Core/MG 1000B Expander.
