Glossary A-I


ALI - Automatic Location Identification is a system that queries a secure database on behalf of a PSAP for the registered 911 address associated with the phone number dialled by a person seeking to reach emergency services. The address is immediately relayed by the operator to the relevant first responders. The address you provide when initially setting up your account will be registered by Telebroad in the ALI database. It is important you keep your address up to date. Change of address is possible from your Telebroad account's web interface or by contacting customer service. 

ATA adapter - Analog Telephone Adapter is a device that connects traditional analog telephones and fax machines to a VoIP network. It allows companies to avoid having to operate and maintain two telephone networks (standard and VoIP).

A2P Messaging (or A2P SMS traffic) - A2P stands for application-to-person. It is a type of one-way automated text messaging communication where the the sender is an application or a computer program and the recipient is a person. It is mostly used for alerts and reminders, short marketing messages, special offers, and access verification codes. See also P2P Messaging.


Busy Lamp Field (BLF) - a set of illuminated buttons on a physical phone that provide visual indication for busy (usually red light) and available (usually green light) lines and extension on the PBX system. The buttons can also be pushed to dial an available line or extension. The TeleConsole has software settings to set up BLF. Read about it and the difference from speed dial here.


Caller ID (Inbound/Outbound) - Caller ID is the number transmitted when making a phone call and is not necessarily same number as your own line number or your company's main number. VoIP platforms allow extra flexibility in this regard. Caller ID may also include a name associated with the number. With Telebroad PBXellent system, a full 10 digits outbound caller ID is assigned to the shorter internal line number or extension for the purpose of making outside calls. Inbound caller ID is the number presented to you on the TeleConsole from outside callers. 

Call Detail Record (CDR) - a grouping of data fields in a report that provide information about the properties of the calls dialled or recieved by a user (without including the actual call content). Typical CDR details include data and time the call started, duration of the entire, actual talk time, caller and recipient phone numbers, caller and recipient phone numbers type, direction of the call,  status of the call and more. CDRs are also available for SMS messages. CDRs are usually used by phone companies for billing purposes and include a data field for cost of the call or per minute cost. For the Telebroad administrator, however, CDRs are more useful for examining call history reports and call flows (the later does include audio recording of certain call segments). These are not actual CDRs, but an interpertation of their data. Viewing of an actual CDR report is possible using our relevant API request..

Call Flow - a call between two private individuals usually involves only two interactive points - a source and a destination (that is not to say the call does not get routed more times on the national phone system. But the routing is automatic and non-interactive). A call in a PBX system, on the other hand, can have many more interactive points along the way. It may arrive in the IVR, get routed to a department, get placed in a hold queue, and then get picked up by an agent. The progress of the call between these points is referred to as the Call Flow. Call flows information, including any relevant recordings, can be observed with the call logs function in either the ACD Panel or Analytics or by sending this API request.

Circuit switching  - a network connection method where a dedicated wiring path is established between a source and a destination before the transmission occurs. Circuit switching is traditionally used with analog telephone communication. A continuous wire connection is created in the telephone exchanges once a call is from one telephone is picked up by the recipient. While the connection is in session the only data that travels on it is between the two connected phones. The data is sent continuously and in sequence, unlike the divided data in Packet Switching.  This gurantee call quality and reliability at the expense of lesser network capacity (since lines can't be shared). 


Dial Patterns - is the format and length of the sequence of digits required for making an internal or external call. An internal extension usually has three digits while external numbers are ten digits long. The later may be eleven digits or longer if the pattern configuration on the server requires a prefix to obtain an outside line or for connecting to different area codes. Rules can also be set on a serve or dialling applications to remove prefix or simplify a pattern for the purpose of compatibility.  


FXS - stands for Foreign Exchange Subscriber. It is a type of port on analog telephony network (or POTS service) that delivers the analog signal and electric current from a phone company (or the PSTN) to an FXO port (see next term) on analog telephone, fax machine, or other analog devices (the FXO port provides an on-hook/off-hook indication to start and end a call). Offices that have existing FXS ports can connect them to an IP network using a VoIP gateway, a device that can convert multiple analog lines to digital VoIP data. 

FXO - stands for Foreign Exchange Office. It is the port that receives the analog telephony equipment that receives the analog signal delivered from an analog FXS port (see pervious term). Because the signal from the FXS port is continuous, the FXO port is required in order to provides an on-hook/off-hook indication to start and end a call. Offices that have existing  equipment with FXO ports only can connect them to an IP network using an ATA adapter


IPv4/IPv6 - the Internet Protocol is  a communication addressing system used to identify devices on a network and across the Internet. IPv4 (Internet Protocol Version 4) is its fourth revision and most widely used. It is a 32 bit addressing system which limits it to about 4.3 billion devices. With growing number of computing devices (especially smart phones) this limit will be reached in the forseeable future. To deal with this the IPv6 version was introduced. It is a 128 bit addressing system with more than 3 Duodecillion possible addresses (3 followed by 38 numbers). It also offers additional configuration, routing and privacy benefits. Presently both formats are in use alongside each other and implementation of IPv6 depends on both server and devices support. Your SIP or IP phone are assigned either an IPv4 or IPv6 address when they are provisioned.

ISP - Internet Service Provider is a company that provides your business with connectivity to the Internet. The ISP usually provides both the physical wiring infrastructure (cable, phone lines, fiber optics etc) and the networking access that enables Internet traffic over the wiring. In some rare cases the infrastructure and networking are provided by two different companies, but usually your available infrastructure will also dictate your choice of ISP. Your ISP also gives you a router to facilitate the Internet connectivity. Not all routers may be compatible with VoIP or with Telebroad's services out of the box, but we do have some guidelines of how to adjust them for such functionality. Our support team will occasionally refer you to your ISP if they think an issue with your Telebroad account is due to Internet connectivity problem rather than a problem on our end.
