Electronic Tandem Network
If your company requires a medium-to-large network spanning a large geographic area, nationwide or even
worldwide, Electronic Tandem Network is the answer. An Electronic Tandem Network is a wide-area
private network that tandems calls through one or more switches to route the calls to their destinations.
An Electronic Tandem Network 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 Electronic Tandem Network locations are connected via
analog or digital tie trunks. For example, a DS1 interface can act as a high-speed (1.544 Mbps) digital
backbone for voice and data communications between Electronic Tandem Network locations.
An Electronic Tandem Network can be configured hierarchically. An Electronic Tandem Network can
connect individual switches; it can also connect other private networks (such as Main/Satellite/Tributary
networks) together.
Within an Electronic Tandem Network, 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
Electronic Tandem Network, a user dials a feature access code for the Automatic Alternate Routing feature
plus the 7-digit number, for a total of eight digits.
