Card and Service Configuration
This chapter describes how to configure the MGX 8850 cards and the services they support.
Although the presumption for this chapter is that a plan exists for your network, it reviews some of
the information that supports network planning. Generic instructions for inserting and removing
cards appear in "Chapter 4, "Enclosure and Card Installation."
The services and applicable modules described in this chapter are:
•
Physical and logical configuration of a broadband interface on the Processor Switching Module
(PXM) and, for a stand-alone switch, connection addition
•
ATM service on the MGX-AUSM/B
•
Frame Relay service on the following service modules:
•
Circuit emulation service on the MGX-CESM-8T1 and MGX-CESM-8E1
•
Redundancy and bulk distribution on the Service Resource Module-3T3 (MGX-SRM-3T3/B)

Tasks for Configuring Cards and Services
This section contains a general description of the sequence of tasks for configuring the cards and
their services. It also contains details on how to configure resource partitions and add local
connections and three-segment connections. Detailed descriptions of these tasks for individual cards
appear in subsequent sections.
Modifying the Resource Partitioning
A resource partition at the card level consists of a number of logical connections (LCNs). At the port
level, a resource partition consists of a percentage of bandwidth, a DLCI or VPI/VCI range, and the
number of logical connection numbers (LCNs) available to a network control application. On the

Page 2: Sequence Of Configuration Tasks
Tasks for Configuring Cards and Services PXM, the connections are global logical connections (GLCNs). By default, all resources on a a card or logical port are available to any controller on a first-come, first-served basis. If necessary, you can modify the resource partitioning at the card level or logical port level. Port-level resource modification follows card-level modification, so the available port-level resources depend on whether and how much you change the card-level resource partitioing. - Page 3 Rules for Adding a DAX Connection A DAX con is a connection whose endpoints for the entire connection exist on the same switch. The following apply to the MGX 8850 switch: On a feeder, a DAX con can exist between different service modules or the same service module. A stand-alone node supports DAX cons with one or both endpoints on the PXM in addition to DAX cons between service modules.

A management connection lets a workstation connected through a router control either the local MGX 8850 node or a remote MGX 8850 node that has no workstation.

Service Resource Module Bulk Distribution for T1 Service The MGX-SRM-3T3/B supports a de-mulitplexing function called bulk distribution.

The benefit of this feature is that the number of T1 cables and back cards is greatly reduced. - Page 49 The need for back cards and the choice of bus for redundancy support depends on whether the MGX-SRM-3T3/B must provide bulk distribution: • With bulk distribution, the T1 service modules do not use back cards.
