Introduction

 

 

The following information provides insight into circuits in IMS and how to achieve the best model to fit different  requirements.

 

IMS employs enumerators (Enums) for certain entities to determine direction i.e.,

 

 

                 

In the Port Template Entity there is a field called Type which is a string and can hold the value BI or UNI

 

If a Port Template is initially setup as Type = BI, then subsequent ports created from this template will be Bidirectional:  Direction = 0 and TxRx will not be set.

 

However, if the Port Template is setup as Type = UNI, then IMS checks if the Port’s TxRx field needs to be defined as Tx or Rx.

 

The following Entities are associated to these Enums [Bold is mandatory]
