Staff such as platform assistance personnel use the network to contact central locations for information and assistance in case of emergency or other issues. Telecommunication service providers are discontinuing leased line services used by Tetra networks to backhaul radio traffic to central sites.

The customer wants to continue using their existing Motorola equipment.
