Case Study: An Online Pharmacy builds Redundancy into their network

Background:

An online pharmacy had outages with their provider and wanted to change carriers. They asked us to design a fully redundant system with the new provider that would allow inbound calls from customers to be received in case of T1 failure.

Problem:

If their phones went down, they were unable to service their customers.

Solution:

The new design: 

  1. Dual redundancy with T1 circuits brought in from two different central offices.
  2. Automatic switchover from a downed circuit to the others in case of an outage at any one circuit.
  3. Direct Trunk Overflow: In the event all circuits are down, all inbound calls are automatically forwarded (from the carrier’s switch) to copper back-up lines. These copper lines were ordered from a different local phone company in case the primary provider has a major outage.
  4. If everything is down, the customer can send all calls to cellular phones.
  5. If cellular phones are busy, customers may leave a voice mail.

Net result: The pharmacy was able to receive customer phone calls after a back-hoe dug up the telecom conduit in the street.
