Nortel Networks NN43001-563 Network engineering guidelines overview

92 ITG engineering guidelines

A maximum of 16 Media Card 32-port trunk cards can ﬁt on one IPE

shelf. Each IPtrunk card takesup one sloton the IPEshelf. 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 451).

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 Trunkcards, 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 Trunk3.01 (and later) system

management trafﬁc; it connects to the ELAN subnet.

Scope These engineering guidelines address the design of the IP Trunk3.01 (and

later) network, which consists of the following:

•IP Trunk3.01 (and later) nodes

•TelephonyLAN (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 Trunk3.01 (and later) nodes are to

be installed.

Network engineering guidelines overview

Previously,Meridian 1 networks depended on voice services such as

LEC and IXC private lines. With IP Trunk 3.01 (and later) technology,the

Meridian 1 and CS 1000 systems can select a new delivery mechanism, one

that uses packet-switching overa data network or cor porate intranet. The

role of the IP Trunk3.01 (and later) node is to convert steady-stream digital
