Additional Routing Considerations
Transmission Processors and Drive Mapping
For each Imaging destination that it sends exams to, the transmission processor will map a drive using the following progression of drive letters: Q – Z, then G – P. If a drive letter (Q, for example) is not available, it will move to the next letter (R, for example) and so on. When all entries for a particular destination have been processed, the applicable drive is unmapped. This logic is not used for DICOM destinations.
Factors Affecting Routing Speed
Given a T1 connection and a light to moderate amount of network traffic, the first images in a routed exam will typically begin arriving at a destination within minutes. However, any of the following can impact the delivery of routed exams:
A backlog of images at the Image Gateway, which is responsible for adding entries to the rule evaluation queue.
A backlog of entries in the transmission queue. If numerous large exams are flagged for routing in a brief period of time, there will be a delay while all the images in the exam are transmitted. In situations where multiple destinations are being used, additional transmission processors may be used to alleviate delays. For more information, see page 51.
Problems connecting to destinations. For Imaging destinations, the routing software will attempt to
