[ih] Internet/Wireless Principle of Levelness

[Andrew G. Malis via Internet-history]

Geoff,

No problem. However, during my stint at Verizon, we certainly weren't
scared to mix and max infrastructure from multiple vendors where it made
sense to us. We had a huge interoperability lab where we
satisfied ourselves that it would work in the field before deploying, of
course. Multi-vendor interoperability was often an RFP requirement.

Cheers,
Andy
