• For OC-12c, 13 bits split between NumVpiBits and NumVciBits.
NumVpiBits cannot exceed 8 bits for OC-12c.
scrambling Enables or disables scrambling.
framing-mode Sets the framing to:
• sonet, which means the Synchronous Optical Network format;
standard format used in North America.
• sdh, which means the Synchronous Digital Hierarchy clock format;
