ProgrammingD-11 Appendix D - Voice Over the Internet Protocol Setting Up the CO Line Groups (FLASH 40) The CO Line Group must be programmed for the Discovery VoIP CO lines. In addition, a TIE circuit must be established to provide system-to-system connectivity. 1. While in programming mode, dial [FLASH 40]. 2. Dial the appropriate range that equals the CO time slots used (e.g., 001-008 or 006-013), then press HOLD. 3. Press Button 8, enter an available Line Group (01-23) based on your existing system programming, then press HOLD. 4. Press Button 20 (Page B), then press Button 1. 5. Dial [5], then press HOLD. Networking Tables (FLASH 16) Networking Tables identify the system number (01-16), the CO or line Group (00-23), the range of station numbers (from xxxx to xxxx), and the IP address for each system. The system number is a database identifier. The CO or line group identifies the line group the system should access when the associated extension number is dialed. The extension range defines the extensions that can be reached at the associated remote system. The IP address provides the IP information of the remote system that is associated to the extension range, CO or line group, and the system number. When a specific extension is dialed, the system looks up the extension in the networking table to determine the line group to use. The line group is then accessed and the Discovery VoIP card establishes the IP connection to the remote system using the associated IP address. 1. Enter programming, then dial [FLASH 16]. 2. Enter the system to be modified (01 to 16). The Discovery VOIP card uses 8 CO time slots. Unused COs on the Discovery VoIP card do not have to be placed in Line Group 00 (e.g., a 4-port VoIP card takes 8 CO time slots, but only 4 CO lines are used) since the software disables unavailable VoIP ports automatically. T1/ISDN SIGNAL TYPE 0-7 TIE Make sure that your 4-digit dialing plans on the remote systems do not conflict with your local dialing plan. If there is a conflict, users will be required to access the VoIP line group first and then dial the remote extension. Otherwise, dialing the 4-digit extension directly will connect the caller to a local system extension and not the remote system extension. For example, if System A uses extensions 1000-1099 and System B uses 1000-1099, a user on either system could not dial the remote system directly because local system extensions take precedence over remote system extensions. In this case, a user would have to access the Discovery VoIP line group and dial the remote system extension to bypass the local system’s dialing plan. The Discovery VoIP CO’s default into Line Group 1. The line group may need to be changed for proper operation on your particular system. Refer to the FLASH 40 programming section for more information on changing line groups.
D-12Programming Appendix D - Voice Over the Internet Protocol 3. Press the appropriate button listed below to modify the table. Conditions » Feature access codes must not conflict with station numbering. » CO line numbers are fixed and cannot be changed other than the current FLASH 42 reassignment. » The VMID digits need to be programmed separately. » The SMDR will output up to 4-digit numbers in the station field. If less than 4 digits are selected in the numbering plan, leading spaces will be added in place of numbers. Call Accounting devices need to be configured to accept 4 digits. » When systems are tied together, each system has to have access to 911 through local lines. Button 1 - Line group programming (00 to 23). Button 2 - Station from (start) range – must be 4 digits. Button 3 - Station to (end) range – must be 4 digits. Button 4 - IP address to dial when any station within that range is dialed. For example, if station 3001 is dialed, the telephone switch connects the call using the IP address: 102. 38. 56. 1 (refer to Ta b l e D- 3 ) Button 22 - Page to next Networking table. Button 23 - Page to previous Network ing table. Button 24 - Enter a new Networking table.

OperationD-13 Appendix D - Voice Over the Internet Protocol Operation The Discovery VoIP card operates like all other Central Office cards. There are up to 8 lines per card, and each line functions as any other CO line functions. It allows bi-directional communication and monitors for disconnect while using minimal bandwidth. It also allows four-digit dialing and other features. When using Discovery VoIP lines: If a button is programmed, a busy lamp field (BLF) will illuminate (on initiating station only) when a CO line is in use. Calling can be done using speakerphone, handset, or headset; bi-directional communication is the default. After a call is connected, it has the ability to use End to End signaling, which allows DTMF to be sent over the connection. This is used for functions such as remote VM systems. Each line monitors for disconnect signaling, simulating Loop Supervision. When a line is off hook for 5 seconds or more, and no action is taken, an error tone sounds. Network Connection When the network cable is removed, or the network goes down, all COs will go out of service. All calls will be denied and an error tone will be heard if the line is accessed. Dialing Use Networking Tables (FLASH 16) to program stations to automatically use the appropriate line group and IP connection for a dialed number. Line Access Off Net Forward A line is allowed to be transferred to a station that is Off Net Forwarded to a remote location. DTMF Only The VoIP card only supports tone dialing (DTMF). 911 Support The Discovery VoIP card does not support 911 calls. Therefore, the system cannot solely use Discovery VoIP CO cards. Station Access Discovery VoIP CO access for each station is allowed or denied access to these trunks through standard CO Line access.
D-14 IP Telephony Standards and Protocols Appendix D - Voice Over the Internet Protocol IP Telephony Standards and Protocols The Discovery VoIP card uses the H.323 Revision standard for call processing. This is an updated version of the H.323 standard. It provides a set of standards defining real-time multimedia communications and conferencing over packet-based networks. These standards define how components that are built in compliance with H.323 set up calls, exchange compressed audio and video, participate in multi-unit conferences, and operate with non-H.323 endpoints. The IP telephony standards/protocols shown in Ta b le D - 4 are adhered to by the Discovery VoIP card. Table D-4: IP Telephony Standards/Protocols Standard Description H.323 Revision 2 Supports H.323 terminals and is the basis for all IP telephony. H.225 Media Packetization Provides media packetization and synchronization for video/ audio telephony on non-guaranteed quality of service LANs. H.245 DTMF Signaling Close Logic Signaling Round Trip SignalArbitration of GSM compression -- provides the new audio capabilities and supports the signaling entities required for call control functions for multimedia communications, while it specifies the in-band signaling protocol necessary to establish a call, determine capabilities, and issue the commands necessary to open/close the media channels. Supports signaling of a pair of associated unidirectional channels which allows for the establishment of a T.120 data channel. Allows determination of the round trip delay between two communicating channels. G.165 Echo Cancellation When echo is present, a preprogrammed button is available to increase or decrease the latency of that call. Upon termination of each call, the unit restores the default setting. G.711 Pulse Code Modulation of Voice FrequenciesTransmits and receives A-law and U-law PCM voice at digital bit rates of 48, 56, and 64 Kbps. It is used for digital telephone sets on digital PBX and ISDN channels. Support for this algorithm is required for ITU-T compliant videoconferencing. (slowest protocol) G.723.1 5.3 Kbps compression for dual rate speech coders for multimedia communicationsRuns at 6.3 or 5.4 Kbps a compression and uses linear predictive coding directory for an open architecture to ensure connectivity with other switches. Moreover, this compression helps provide smoothness. (Default) G.729 Speech encoding 8 Kbps Encodes/decodes speech at the rate of 8 Kbps using conjugate- structure, algebraic-code excited linear predictive methods. Q.931 Messages: - Progress - Setup - AcknowledgmentCreates a unique global identifier that allows all messages associated with a call to be interoperable between the registration, administration and status protocol used in IP networks utilizing the Q.931 signaling protocol used in circuit-switched telephony networks. Supports messages that are used for call signaling, including all mandatory and conditionally mandatory messages, some optional messages and information elements, and the facility message defined in Q.931 and Q.932.

E Customer Database Programming This appendix provides information about database programming. Use the detailed procedures contained in other chapters and appendices for actual programming via executive display telephone. Use the Customer Database Worksheets in this appendix to help keep track of the system programming changes made for each individual system.
IntroductionE-3 Appendix E - Customer Database Programming Introduction The XTS system is programmed to meet each customer’s individual needs. All programming is done at any 24-Button Executive Telephone as the programming station or through an ASCII terminal or PC. The digital display model is required for programming. When the programming mode is entered, the digital telephone being used no longer operates as a telephone but as a programming station with all of the buttons redefined. The keys on the dial pad are used to enter data fields (Program Codes) associated with system, station, and CO line features as well as specific data that requires a numeric entry. Flexible buttons toggle on or off features, or enable entry of specific data fields. LEDs and the LCD display provide a visual indication of entered data and their value. Programming is also performed using an ASCII terminal, or a computer capable of emulating an ASCII terminal. This form of programming is done locally (on-site) by connecting the terminal directly to the RS-232C connector on the Main Processing Board (MPB) or is performed remotely (off-site) through the use of the 19.2K baud modem. The method and steps to program the system via a PC are identical to those used when programming from a digital key set. A button to keyboard mapping is provided (refer to Figure E-2 on page E-4) to help minimize familiarization and training time. The system must be initialized to load default data into memory at the time of installation. If this pre-programming is acceptable to the customer, initialization is all that is needed. Refer to Ta b le F - 1 o n p a g e F - 3 for a listing of all the default values. When features are programmed, tones are provided to determine if a correct or incorrect entry has been made. A solid one second tone indicates the data was accepted. An interrupted tone means an error was made. When this occurs, re-enter the data and information. Until new data is entered and accepted, the system continues to operate under default or previously entered values. The system database is updated on a real-time basis as new data is entered, by pressing the Hold button. The system continues to operate with the current database and is updated with any newly entered or changed data without interruption to telephone operation or call processing in progress. However, if for example a station’s attributes are changed while that station is off-hook on an active call, the newly entered data does not take effect until the station goes on-hook or becomes idle.
