92 ITG engineering guidelines
A maximum of eight ITG-Pentium 24-port trunk cards can fit on one IPE
shelf. Each card takes up two slots on the IPE shelf.
A maximum of 16 Media Card 32-port trunk cards can fit on one IPE
shelf. Each IP trunk card takes up one slot on the IPE shelf. For Class B
compliance to EMC regulations, only 10 Media Card 32-port trunk cards can
be placed on an IPE shelf. For Class A compliance, there are no limitations
on the Media Card 32-port trunk card. For more information, see
Appendix
"Environmental and electrical regulatory data" (page 449) .
An IPE shelf can contain a mixture of ITG-Pentium 24-port trunk cards
and Media Card 32-port trunk cards.
Cabinet systems operating under Class B Electro-Magnetic Compatibility
(EMC) standards can only hold a total of two IP Trunk cards, divided
between the main and expansion cabinets. This can be extended to two
cards in each main or expansion cabinet if all cabinets are separated from
each other by at least ten meters distance. For Cabinet systems operating
under Class A EMC standards, there are no restrictions.
For Meridian 1 Option 11C Cabinet, Meridian 1 PBX 11C Chassis,
CS 1000M Cabinet, and CS 1000M Chassis systems, the SDI/DCH
(NTAK02BB) card occupies one slot on the cabinet and is connected to
the IP trunk card through the backplane. Only ports 1 and 3 are available
for use as DCHI.
The IP trunk card uses a 10BaseT Ethernet network interface located on
the card backplane I/O connector to carry IP Trunk 3.01 (and later) system
management traffic; it connects to the ELAN subnet.
Scope
These engineering guidelines address the design of the IP Trunk 3.01 (and
later) network, which consists of the following:
• IP Trunk 3.01 (and later) nodes
• Telephony LAN (TLAN) subnets to which the IP Trunk 3.01 (and later)
nodes are connected
• A corporate intranet which interconnects the various TLAN subnets
These guidelines require that the customer has a corporate intranet in
place that spans the sites where the IP Trunk 3.01 (and later) nodes are to
be installed.
