Electronic Tandem Network 10 Networking

An important DEFINITY ONE networking feature is Main/Satellite Extended Trunk Access. Extended Trunk Access allows dialed digits that are undefined at a satellite or tributary switch to be routed over a trunk group to a main switch for interpretation.

This flexibility means changes to the network numbering plan do not have to be propagated to all switches. Extended Trunk Access improves your control and reduces administration costs by making trunk networks considerably easier to maintain.

Electronic Tandem Network

If your company requires a medium-to-large network spanning a large geographic area, nationwide or even worldwide, Electronic Tandem Network (ETN) is the answer. An ETN is a wide-area private network that tandems calls through one or more switches to route the calls to their destinations.

An ETN consists of tandem switches, inter-tandem tie trunks that interconnect them, access or bypass trunks from tandem switches to main switches, and the software and equipment to support call routing over the trunking facilities. Different ETN locations are connected via analog or digital tie trunks. For example, a DS1 interface can act as

ahigh-speed (1.544 Mbps) digital backbone for voice and data communications between ETN locations.

An ETN can be configured hierarchically. An ETN can connect individual switches; it can also connect other private networks (such as Main/Satellite/Tributary networks) together.

Within an ETN, each location is identified by a unique private network location code, similar to the public network office codes that exist within an area code. When accessing the ETN, a user dials a feature access code for the Automatic Alternate Routing feature plus the 7-digit number, for a total of eight digits.
