For example, a food delivery service agent needs to call you to update you on the status of your order (let’s say Wendy’s 533-3333), if they have a DoD service in their system, any agent that will call you for an update will have the 533-3333 displayed at your caller ID. Having in mind the concept of Trunk Lines (one number + multiple lines), if you call out of your office, what number would reflect in the called party’s caller ID display? (Hmmmm… Intriguing…) The answer can be two things (1) if you did not purchase DoD service, it will be random number in your number block (from 890-1000 to 890-1099) or (2) if you purchased DoD you can have it customized to any number within the number block you have. DoD – Direct-Outward-Dialing DoD from the definition, is the opposite of DiD but with a little twist.1008, you just need to dial 890-1008 to talk directly to that person. DiD – Direct-Inward-Dialing now, with the understanding of how trunk lines work, what if you specifically want to talk to a certain agent/person? Here is where DiD comes in handy, if you know the extension number of the person you would like to talk to, i.e.An example of a Trunk Line is a food delivery number (let’s say 8-MCDO), there is only one number you need to remember and dial, but when you call that number (repeatedly) you will notice that there are several agents who can receive your call. Now if you you have a Trunk Line, it will allow you to be contacted by multiple callers at a time, the number of callers-at-one-time (or in IT we call it concurrent) will depend on how many you want to avail from the TelCo. Meaning, if two callers dial the number at the same time, one can connect and the other will hear a busy tone. Trunk Line – this is a service which will allow you to have one number, but, you can use it with multiple lines (is it confusing? Let me explain further…) For example a company has a number as 890-1000 (I apologize if this is a commercial number, but let me just use this for discussion purposes), if your line is an ordinary line, only one person can call 890-1000 at time.Extension Number – or local number, usually a four digit number so you could call your officemates within your office this is a unique number assigned to each person in the organization.a company that needs 100 numbers may get a 890-10XX from a TelCo, that will mean that, the numbers 890-1000 up to 890-1099 will not be given out to other companies (or other landlines for that matter). Number Block – companies usually avail of a number block, i.e.Ordinary Line – similar to the ones we have at home, if you get an ordinary line, you will have one number to call from and to.Caller ID – I think we are familiar with this one, this is a service where you can know what number is calling you (of course, you must have one of those digital displays or a phone with a digital display).Services(for PSTN Lines) – or we may call this as features, but when we subscribe with a TelCo, we use the word ‘Services’ instead below are some of the services offered.PSTN Line – PSTN stands for Public-Switched Telephone Network or let’s call it Analog TelCo Lines you can think of this as a ‘landline’ (the ones we have at home) but with more features (or Services).TelCo – Telephone Company for example PLDT, Globe, etc.This will be a three-part Tech Update with topics on ‘Traditional Telephony Systems’, ‘ Voice over IP‘, and ‘Unified Communications’ Part 1: Legacy Telephony Systems Terms 😉 (It would have been better if I could use everyday household examples, but for me to make my point, some examples need to be on a larger scale.) In this three-part blog, let me try and share this innovation with you without making your nose bleed.
Communications has evolved over time, an example we could all relate to is making a voice call using your Yahoo! Messenger or Skype vs using your landline to make long-distance calls to your loved ones abroad.
