A、A. Establishing a signaling channel between two signaling entities in an ATM network B、B. Provide reliable connection for signaling between two IP signaling nodes C、C. Provide routing for IP signaling messages in an IP signaling network
A、Each fiber has half of its SONET capacity reserved for protection. B、Two fibers in the span carry working traffic, while the other two fibers in the span are reserved for protection. C、The signal is sent simultaneously in both directions around the ring. The receiver determines which fiber to listen to based on signal quality. D、The signal is sent simultaneously in both directions around the ring. The transmitter determines which fiber has the working bit set for the receiver to acknowledge.
A、A unique radar signal consisting of a blip code radiating outward from a SART's position along its line of bearing B、A unique two tone "warbling" signal heard on VHF-FM ch-70 C、A unique two tone alarm signal heard upon the automatic unmuting of the 2182 kHz radiotelephone automatic watch receiver D、The SART signal appears as a target which comes and goes; the effect of heavy swells on the SART
A、One blast at one-minute intervals B、One blast at two-minute intervals C、Two blasts at one-minute intervals D、One prolonged and two short blasts at two-minute intervals
A、Use an EXP rewrite table. B、Use a DSCP rewrite table. C、Statically assign a CoS value to an LDP-signaled LSP. D、Statically assign a CoS value to an RSVP-signaled LSP.
