Virtual Network Services (VNS) provides ISDN features to customers when
no ISDN Primary Rate Interface (PRI) or ISDN Signaling Link (ISL) Bearer
Channels are available between two Meridian 1 switches. (Refer to the VNS
feature description module in this NTP for detailed information on VNS).
You must configure VNS DNs (VDNs) as part of the numbering plan. The
VNS VDN expansion feature sets a new limit on the number of VDNs at
4000. VDNs are configured on Overlay 79.
The VDNs are defined in sets of blocks. Each block may contain any number
of contiguous VDNs, as long as the total number does not exceed 4000.
Within a block, it is possible to define a range of VDNs as well as individual
VDNs.
