IHE Patient Care Device Technical Framework Supplement – Alarm CommunicationManagement (ACM)______________________________________________________________________________1835The WCTP DTD identifies the URL of the DTD (Data Type Definition) for the indicatedversion of WCTP supported.Table 2-2: WCTP DTD valuesValue Indicating WCTP version MCR supporthttp://dtd.wctp.org/wctp-dtd-v1r1.dtd 1.1 Nonehttp://dtd.wctp.org/wctp-dtd-v1r2.dtd 1.2 Unpairedhttp://dtd.wctp.org/wctp-dtd-v1r3.dtd 1.3 Paired1840The Next Poll Interval is the number of seconds the ACM AM (WCTP client) should waitbefore again polling the ACM AC (WCTP server). The ACM AC (WCTP server) dictates thisvalue to reduce the aggregate polling load on the WCTP server by all WCTP polling clients.Given that there are typically not many ACM AM instances per ACM AC instance this intervalcan be kept to a small single digit number of seconds. In typical WCTP wide areacommunication deployment there are often hundreds if not maybe thousands of WCTP clientsper WCTP server.1845The graphics format indicates the format of the graphical image information, and the value canbe any one of SVG, JPEG, PNG, or BMP as agreed between the ACM AM actor vendor and theACM AC actor vendor.1850The graphical image is a base-64 encoded string representing one of the WCM static graphicalimages represented by one of the sets of WCM evidentiary data from the ACM PCD-04 messagesent from the ACM AR to the ACM AM.1855The telephony dial string is an encoded telephony dial string, including any required prefixes,area codes, PBX switch hops, or pauses needed to permit the ACM AC endpoint communicationdevice operator to make a telephone call from that device back to a patient’s room or to theobservation producer/order filler.18601865The status update is the string indicating the type of status update that the ACM AC is reportingback to the ACM AM in wctp-Notification. Possible values are as QUEUED, DELIVERED, orREAD. Additionally there are the optional IHE PCD ACM profile specific values forIHEPCDCALLBACKSTART and IHEPCDCALLBACKEND in support of Call Back Numberphone dialing by the operator of the ACM AC endpoint communication device and the resultingtelephony call start and call end, the status of which are useful as logged items in alarm responseanalysis.__________________________________________________________________________72Rev. 1.3– 2012-08-16Copyright © 2012: IHE International, Inc.
