Chapter 4 Configuration Tables and Fields

Port Concentrator

Port Concentrator

The Port Concentrator provides a method for concentrating voice and data connection types as a Frame Relay connection extending to an FTC or FRM card. The NMT models and provisions Port Concentrators so that they support Frame Relay connections. The card is modeled as a 44-port FRP card, with the PC interface being optional but defaulting to V35.

Refer to Table 4-23for information on modeling a network that uses port concentrators.

incorrect.

 

 

 

Fdr BC (feeder back card) field: Each PC termination can also specify which

 

 

PC interface is required. Enter V (for V.35), V1 (for V.11) or V2 (for V.28) in

 

 

the corresponding Fdr I/F field. If you leave the field blank, the interface

 

 

defaults to V.35.

 

 

Hub ID (for Site 1 and Site 2) fields

 

 

• The port ID is the slot.port ID for an FRP-PC card and is a virtual port. The

 

 

virtual port range is from 1 to 44, where ports 1 to 11 are on physical port 1,

 

 

12 to 22 are on physical port 2, 23 to 33 are on port 3, and 34 to 44 are on

 

 

port 4.

 

 

• Hub IDs can be used to model over-subscription, port-to-multiport

 

 

connections, and multiple PCs.

 

 

• A hub ID of 0 allows NMT to do design.

 

 

FdrID (Feeder ID) field: Not used

 

 

Access Ports table

 

 

Hub ID field: Slot is the PC slot and port is the virtual port (1 to 44). Do not

 

 

use feeder slot or feeder port column.

 

 

Speed field: Enter the port speed. If not supported, it will be rounded up to the

 

 

nearest supported speed. Speeds 9, 14, 19, and 38 will be respectively

 

 

interpreted as 9.6, 14.4, 19.2, and 38.4. If you have an Access Port table entry

 

 

for a PC port, the port speed is determined by the connections assigned to it.
