GMN Assignment - Type 610
GMN Assignment (Type 610)
The primary intention of this packet is to specify the GMN to GMH mapping for a previously submitted T2 forward message. QTRACS will format and send this packet upon receipt of a message submittal acknowledgement indicating that a T2 forward message has been successfully sent.
GMN Assignment transactions are routed to the same external application that has sent the corresponding forward message (this should always be TrailerTracs).
