Organisations are looking to enhance their preparedness against disruptive events by eliminating single points of failure within their voice and data networks. While they can control the resilience within their own networks, organisations are still dependent upon external networks, such as the PSTN, for the delivery of incoming calls. A failure to deliver incoming calls can impact the revenue and reputation of the business, and organisations are therefore keen to protect themselves against this.
One such potential exposure lies in the Local Exchange. Traditionally, a customers’ DDI range is associated to a series of ISDN channels within a serving local exchange. For resilience purposes, a failure within the local exchange creates a single point of failure for incoming calls and customers are keen to understand how to protect against this rare occurrence.
