With dynamic integrated service, phones get the priority to ensure high quality voice traffic, but when the phones are not in use, the bandwidth is returned to the data side in real time. As an example, with a full dynamic integrated DS1, 1540 k (t1 bandwidth) is assigned to the data side. If one phone is being used, then subtract 64 K (varies) from the 1540 k, if two phones are being used, subtract 128 k, and so on. When the user hangs up the phone that bandwidth is automatically returned to the data side. With dynamic integrated, you will always have 1.54 mbps (megabits per second) when phones are not in use.
One integrated DS1 line, depending on availability in your area, can bundle any combination of the following applications: local telephone service, long distance, incoming toll free, internet, and/or VoIP. Integrated DS1 is very popular with small and medium sized businesses that do not want to pay for separate T1 circuits for each of these applications. Other advantages of integrated DS1 can include: one provider, one easy to read bill and one point of contact for all of the above mentioned services, flexibility in keeping your existing phone numbers, much lower costs than if the above mentioned applications are purchased individually, and the flexibility to evolve as your business grows.
