Support for AT&T’s Software Defined Network (SDN) was first offered with
MERLIN LEGEND in Release 2.0. Release 4.2 introduced support for VNET,
MCI’s version of SDN.

Sprint offers VPN Premiere; this virtual network is not supported by

MERLIN LEGEND.
With Release 6.0 and later systems, UDP routing via 3-, 4- or 5-digit dialing offers
SDN customers simplified dialing. An SDN dialing plan identifies all network
locations with a dialing plan of up to 10 digits. Users at all locations in the private
network can be identified with 3- or 4-digits (unique). This uniqueness criteria may
require some users whose last 3- or 4- digits are identical to change their
numbers.

numbers.
For example, if each MERLIN LEGEND in the private network is configured with a
4-digit dial plan, the routing patterns can be set up to prepend the digits needed to
support an SDN 7- or 10-digit dialing plan. To support the 7- digit dial plan, four
digits must be prepended; to support the 10-digit dial plan, six digits must be
prepended. This configuration must be coordinated with the SDN/VNET provider.
