Description

 

 

 

Share Redundancy

Y

Y—non-redundant connections can share cards that are used on

 

 

redundant connections, essentially getting redundancy for free.

 

 

If no, non-redundant connections cannot share these cards, and are

 

 

provisioned by a separate non-redundant service module.

 

 

 

Reserve pkt/swt

N

Y—hold a packet switch in reserve for the VDP background test of

 

 

standby cards.

 

 

 

Adavtive VAD

N

Y—all voice connections will be treated as they are in the PROTECT

 

 

state.

 

 

 

Use Time Stamp Queue

Y

Y—then low speed data connections on LDP and SDP cards will be used

 

 

 

Bundle Parts

Y

Y—provision bundled parts when possible in the parts list.

 

 

 

FR Route Choice

Y

Y—route FR connections for optimal bandwidth usage. If N, route FR

 

 

connections for optimal performance.

 

 

 

Priority Bumping

N

Y—use the priority bumping algorithm for re-routing of connections.

 

 

Connections with higher COS can bump lower priority connections in

 

 

order to reroute.

 

 

 

Model PNNI RCC & SSC

Y

Y—automatically create and provision the PNNI signalling connections;

 

 

the PNNI Hello Protocol (RCC) and the PNNI Signalling Protocol

 

 

(SSC).

 

 

 

Special Settings Menu

N

Add two new menus which enable you to alter internal parameters of

 

 

basic Cisco products.

 

 

 

Feeders

Specify all feeder equipment in the MGX, IGX, and IPX products explicitly in the Sites table. You can also use the NMT to provision feeders as required by the connection demand. You can even provision additional routing IGXs.

Implicit and explicit feeder generation is discussed in the following sections:

•Modeling Implicit Feeders

•Modeling Explicit Feeders

Modeling Implicit Feeders

To allow NMT to generate implicit feeders, enter the following information into the Site Table:

•hub site

•link connecting the hub to the feeder

Enter information about both the hub and feeder interfaces in the Traffic tables. For implicit feeders, connection endpoints are the hub nodes. The actual feeder ends cannot be referenced directly. IGX, IPX, and MGX8820 feeder nodes can be implicitly generated by NMT. The MGX 8850, if used as a feeder, must be an explicit feeder.It can not be an implicit feeder.

Implicit IGX and IPX feeders are generated when a BPX is used as the hub node for Voice or Data Traffic. They are also generated when a BPX is used as the hub node for Frame Relay Traffic not designated for an MGX 8220.
