Physical description 571• Tie Two-way Dial Repeating (DR) and Two-way Outgoing AutomaticIncoming Dial (OAID)• Paging (PAG)Note: All-call zone paging is not supported.• Recorded Announcement (RAN).The Universal Trunk Card also supports Music, Automatic Wake Up, andDirect Inward System Access (DISA).Table 232 "Supported trunk type and signaling matrix" (page 571) is a matrixof the trunk types and signaling supported by the Universal Trunk Card.Table 232Supported trunk type and signaling matrixCO/FXWATSDID/DOD Tie PAG RANLoop start yes no no no noGround start yes no no no noLoop dialrepeatingno yes yes no noLoop OAID no no yes no noPhysical descriptionThe trunk and common multiplexing circuitry is mounted on a 31.75 cm by25.40 cm (12.5 in. by 10 in.) printed circuit board.The NT8D14 Universal Trunk card connects to the backplane through a160-pin connector shroud. The backplane is cabled to the I/O panel, whichis cabled to the Main Distribution Frame (MDF) by 25-pair cables. Externalequipment, such as recorded announcement machines, paging equipment,and Central Office facilities, connect to the card at the MDF. Each unit on thecard connects to the backplane through an 80-pin connector, the backplaneis cabled to the Input/Output (I/O) panel, and the I/O panel is cabled tothe cross-connect terminal. At the cross-connect terminal, each unitconnects to external apparatus, such as Central Office facilities or recordedannouncement equipment. Each unit connects to external apparatus by tipand ring leads which carry voice, ringing, tone signaling, and battery.See the Communication Server 1000M and Meridian 1 Large SystemInstallation and Configuration (NN43021-310) for termination andcross-connect information.Nortel Communication Server 1000Circuit Card ReferenceNN43001-311 01.04 StandardRelease 5.0 23 May 2008Copyright © 2003-2008, Nortel Networks.
