Virtual DIDs Definition Continued.
Local DIDs have allowed PRI customers (businesses) to have many more local phone numbers than the actual number of phone lines they were paying for. As an example, a business that utilizes a local voice PRI for their telephone service has access to and is paying for 23 usable local voice lines. With local DIDs, for a few dollars more, this company could actually have 100, 200 or more local phone numbers that would be routed through their 23 voice lines. With local DIDs a company that has 100 employees, but only needs 23 voice lines to meet their needs, can actually give the appearance that each of the hundred employees actually have their own phone lines. In reality, each employee has their own local phone number but is sharing the 23 voice lines with the other 99 employees. Each of the 100 DIDs are coordinated through one of the 23 voice lines by a PBX. Of course this system will only facilitate 23 simultaneous calls. This scenario is common in the business world because industry averages for employees to be on the line at the same time is about 20%. With virtual DIDs, this concept can now be generalized to other geographic locations, including other countries. As an example, a company located in Seattle, that is utilizing SIP T1 voice service, can now have virtual DIDs (local phone numbers) in Dallas, Chicago, Miami, London and Paris. For each of these cities, the phone number being dialed will be local to that city, but will actually ring into the Seattle location. This scenario provides a least two major advantages. First, other than the approximate $25 monthly charge for each virtual DID, there is no per call charge to either the caller, or the receiver of the call. Second, if desired, the virtual DID in the example above, allows the company in Seattle to appear to have a local presence in Dallas, Chicago, Miami, London and Paris.

Is MPLS Causing Frame Relay to be Obsolete?
Writen by: Dennis Green
MPLS (multiprotocol label switching), is only one of many factors that are resulting in a diminishment of demand for frame relay. Other factors include the lower cost of clear channel T1, increased demand for; VOIP (Voice over Internet Protocol), video conferencing, class of service (CoS), and a tendency toward converged services on one large pipe. At one time, and for many years, frame relay was considered the state-of-the-art broadband technology. This time has now passed. Many substantial businesses continue to rely on frame for their bandwidth and networking needs, but in most cases, this has more to do with procrastination and a lack of understanding about just how easy, and cost effective it would be to switch to a fully managed, any-to-any location network based on MPLS technology. In the not to distant future, virtually all companies will switch from frame, to MPLS based networks. To make this change now is virtually free. Installation is commonly free, the routers, and configuration of routers is often free, the cost of MPLS bandwidth is usually far lower than bandwidth provided with frame relay, and the speed of bandwidth provided with MPLS is often far higher than the much smaller circuits utilized with frame for the same cost. MPLS networks are often completely managed by telecom providers, thus lowering customer costs for networking staff and reducing the workload of often overworked IT personnel. MPLS has far more abilities than frame. For example, with MPLS, many applications can be provided over one circuit simultaneously. This eliminates the need for individual circuits for each application. With MPLS, the need for a multitude of permanent virtual circuits (PVCs) needed to connect various network locations is eliminated. MPLS based networks provide any-to-any network location connectivity without the need for a myriad of PVCs required with frame. MPLS easily facilitates routine data transfer, VOIP, and video conferencing simultaneously with application prioritization. This prioritization, accomplished with CoS, prevents routine data transfer from interfering with higher priority applications such as VoIP and video conferencing utilizing the same circuit.
