With a new range of Digital Products and telephone services available, customers can often be confused by technical jargon fed to them by telephone providers.

Birmingham Telecommunications are experts in the provision of telephone lines and will help you make the correct decision when trying to decide whether you need analogue or digital telephone services.

Below is a guide to when you may need ISDN (digital) service.  There are 2 kinds of ISDN service that will apply to your business.  Each is explained individually.

Both ISDN services are available directly from Birmingham Telecom by calling us on 0121 747 2524.  If required our qualified engineers can visit your premises to help you make a decision on how to move forward and to discuss whether ISDN is required.

ISDN 2e

ISDN 2e to you can be simply explained as being 2 x Phone Lines (a pair) within 1 box.  ISDN 2e lines are digital and are mostly always connected to a telephone system when used.

Before broadband was common, ISDN 2e was a very popular  way to receive a slightly improved internet service as it was faster than a standard 56,000 KBPS modem but with broadband now being available everywhere this service is only used on very rare occasions for internet access.

• Once connected to a telephone system, ISDN 2e will allow your business to use DDI numbers (direct dialing in). This allows your staff to have their own direct telephone number for customers to call into. This service is NOT available to analogue telephone users.
• When using ISDN 2e, our engineers will be able to dial into your telephone system to diagnose problems, make changes or upgrade firmware remotely.  This can save a customer in engineering visits.
• As ISDN 2e is Digital, service quality can be noticably better in certain areas.
• Birmingham Telecom voice recording solutions can connect directly into ISDN 2e lines to record all incoming and outgoing calls in high quality and maximum clarity.

• Digital Line high speed connections for clear voice transmission and fast data transfer (data is only really used now for legacy systems)
• Fast Call Set-up - virtually instantaneous call connection, improving efficiency
• Digital Path - allowing transmission of voice, data, and text
• Public dialed service-pay as you use, multi-site high speed communications at less cost than a private line
• Supplementary Services - enhancement to existing ISDN service
• PSTN call rates (nationally) - expediting cost monitoring
• Circuit switch capacity - to any ISDN and PSTN site, offering maximum flexibility

ISDN 30e

ISDN 30e requires an order quantity of a minimum of eight lines.  For offices of this size and above, ISDN 30e is really the only viable option for a professional business that relies on communications to succeed.  ISDN30e lines are high-performance lines which can be used to run both voice and data services for modern businesses.

Major benefits include :-

• Connections are almost instant
• Voice communications with other ISDN users are crystal clear
• You can send and receive calls to all telephone subscribers, whether they use digital or analogue equipment.
• Data transfer is fast and error free
• There is a wide range of compatible equipment, giving you access to the latest digital technology
• You can provide your staff with individual DDI numbers
• Each ISDN30 connection provides between 8 and 30 independent 64k channels. You can combine these for bandwidth-hungry applications such as high-quality video conferencing or transferring large data files.
• ISDN is ideal for wide-area networks linking two or more office
