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.
NOTE:
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.
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.
