Q51816 Explain the working of broadband telephony system. Also enlighten the concept of business trunking.

Answer:

Broadband Telephony is a revolutionary office telephone system. By converting phone calls into data and delivering them over a broadband connection, it offers:

  1. Substantial cost savings on the maintenance and operation of traditional office phone systems (PBXs), with no hardware investment.
  2. Free calls to other Broadband Telephony users
  3. Improved corporate communication via a wide range of sophisticated calling features for individuals, small and large offices alike
  4. Full enterprise call centre features
  5. User friendly control tools embedded in Outlook/Lotus Notes
  6. Reduced calling costs to other destinations

The solution works by plugging broadband phones into the broadband-connected local area network (LAN). Redwood Broadband Telephony then passes this traffic on to a carrier class, IP Centrex switch to make your existing office phone system (BT line rental, PBX phone system, PBX maintenance, voice mail etc.) entirely redundant.

Broadband Telephony is also ideal for connecting a small remote or branch office to a central site, through a service known as Business Trunking.

Broadband Telephony Business Trunking hooks existing PBXs up to the Broadband Telephony service, using IP Gateways and passing calls over a broadband connection. As such, the service replaces expensive analogue or ISDN lines traditionally necessary to carry the voice service.

By carrying high quality, business-class calls and functionality over a broadband connection the trunking solution offers free on-net calls (between branches), cost-effective upgrades, improved scalability and a unified dialling plan between remote locations.

As Broadband Telephony Trunking supports digital and analogue phones via gateways on the network, user investment is protected. Additionally, existing TDM and IP-based PBXs are also supported, so that Broadband Telephony can bring them into the wider network, and in many cases integrate their call dialling number systems.

Concept of Broadband Telephony

The key features of broadband telephony are:

  1. A Single Centralised System: Broadband Telephony, a next-generation telephone service, can connect multiple sites, wherever they are, enabling other offices to be reached via extension numbers, for free, as if they were in the same building. The system includes a full range of PBX and smart phone capabilities with a single system catering to all sites, providing full functionality for all users.

2. Cost Effective Telephony: All calls between connected sites are free of charge, entirely eliminating long distance call charges between remote offices. Calling costs to other locations are also dramatically reduced.

3. Scalability: Broadband Telephony is based on a carrier grade system and modular design, capable of scaling to support millions of simultaneous calls.

4. Advanced Voice Mail: Advanced voice mail services include customisable voice prompts, for different situations, and a message centre, embedded into Outlook or Lotus Notes, enabling messages to be retrieved from the desktop or any phone.

  1. Self-Care Management Tools: The phone system can be managed via user friendly, easily accessible, web-based tools, with different access and authorisation levels for individuals and site administrators.
  2. Follow Me and Call Screening: Users can easily configure follow-me and call screening preferences via their Outlook or Lotus notes.
  3. Fax to Email: Faxes can be sent directly to email addresses as attachments, without recipients even having a fax machine. There is no need to check for incoming faxes and privacy is no longer compromised as a result of faxes sitting on a shared machine. Multiple faxes can be received simultaneously and once received they can be saved and forwarded in soft-copy.
