MISCELLANEOUS FUNCTION MODULE (MISC)The Miscellaneous Function Module (MISC) daughter board installs in position MCP2-D3 on the MCP2 card in asingle cabinet system or in position SCP2-D2 on the SCP2 or position LCP2-D2 on the LCP2 card(s) in a multiplecabinet system. The MISC daughter board is used to provide external music on hold/audio inputs (radios, digitalannouncers, etc.), external paging auto output, loud bell, common bell and programmable dry contact closures.The system can support up to three of these daughter boards, one on the MCP2 or SCP2 and one on each of theLCP2s.The MISC consists of the following:• Two (2) external music/audio inputs• One (1) external paging audio output• One (1) loud bell audio output• One (1) common bell relay contact closure• Two (2) software assignable relay contact closures2.2.3 SMARTMEDIA CARDSAn OfficeServ 500 system must have a SmartMedia card installed in the main control processor (MCP2) as theSmartMedia card contains the system operating software.The SmartMedia card can also be used to store a back-up customer database to supplement the database stored on the MCP2 card. In addition the SmartMedia cardcan store backup copies of the operating software for the SCP2, LCP2, and TEPRI/TEPRIa cards.2.2.4 INPUT–OUTPUT MODEM (IOM) BOARDThe Input Output Modem board installs in the first cabinet and provides access to the two serial I/O ports on theMain Control Processor (MCP2) card. Ports 1 and 4 are not used on a Release 2 system.The IOM board also has pro-vision to have an internal 56K/V.90 modem installed on it (see Part 2.2.5).2.2.5 MODEM DAUGHTER BOARDThe Modem daughter board installs on the Input Output Modem card. The modem provides a 56K/V90 connec-tion to the system for use for remote administration and/or programming.The card has a default extension num-ber of 3999 and eliminates the need for an external modem, serial cable, single line telephone port and serial I/Oport on the system.2.3 INTERFACE CARDSThese cards provide the interface connections for telephone lines and stations to the KSU and expansion cabi-nets.These cards fit into the universal card slots to configure the system as required. OfficeServ 500 interface cardsare encased in a static dissipative ABS plastic shell to protect the PCB during handling.2.3.1 TRUNK CARDSTRUNK B1This card contains four loop start C.O. line interface circuits with C.O. disconnect detection. It also contains the cir-cuitry needed for Caller ID. It can be inserted in any universal card slot in all cabinets.TRUNK C1This card contains eight loop start C.O. line interface circuits with C.O. disconnect detection. It also contains thecircuitry needed for Caller ID. It can be inserted in any universal card slot in all cabinets.2.5
