Transparent ISDN Substitution

The client is a nationwide broadcaster in the Nordics that requires a high quality voice and data network for outside events, remote studios and international broadcasts. The broadcast equipment uses ISDN interfaces and requires ISDN synchronisation to prevent slippages or dropouts. The service is typically used for commentating at sporting, music, exhibitions and other events. A reliable, high quality service is vital – poor quality or dropouts result in complaints and loss of revenue. This dependable ISDN service has been used for many years and the broadcaster needs to retain high levels of reliability and quality. Broadcast equipment is currently connected to an ISDN line and traffic is backhauled to central sites over PRI or BRI. The customer wants to continue using their existing equipment over an IP network.
