TID Multiplexing: Overview

Overview

AI232 supports TID multiplexing, which enables a single call from an OSS to fan out into multiple calls to various NEs. The initiating call may be asynchronous or TCP, but cannot originate from a destination menu. Refer to Figure 6-1 for an illustration of TID multiplexing.

Figure 6-1 TID Multiplexing Overview

In Figure 6-1, AI232 takes a single call from an OSS and routes TL1 commands to various NEs by means of the TID in the TL1 command. Similarly, AI232 receives TL1 responses and NE reporting messages from several NEs and routes these messages to the appropriate OSS. The call to AI232 from the OSS is a parent call. The calls from AI232 to the various NEs are children calls.

After receiving a TL1 command from the OSS, AI232 checks to see if there is an existing connection for each TID. If a connection to the appropriate NE is already established, then AI232 forwards the TL1 command to the NE as specified by the TID.

The following characteristics apply to AI232 when it attempts to connect to an NE:

zIf AI232 is unable to establish a connection to an NE, it will buffer the TL1 command and try to reconnect within 2 seconds.

zAI232 tries to connect up to three times if it cannot immediately establish a connection.

zAI232 buffers only one TL1 command for each NE. If a connection is made, AI232 forwards the buffered command to the NE.
