Table 2

FTM channel/service types and signaling options.

channel/service type	One-way	Two-way
Continuous wavelength; (𝜆 service)	Hardly an option	Strongly advised
Constant bit-rate; (line service)	Possible	Advised
Adjustable bit-rate; (dynamic line)	Possible	Advised
Assured variable bit-rate; (assured mean)	Possible	Advised
Available bit-rate; (virtual channel)	Best choice	Limited
Assured single burst; (possibly huge)	Hardly an option	Strongly advised
Plain single burst/packet; (rather small)	Best choice	Limited
