Synchronous-Serial Connection
Synchronous
-Serial
-Serial
A connection type utilizing the RVP protocol, encapsulated over HDLC, to send voice
packets over the network (using traditional network devices: TA, CSU/DSU, FRAD)
using a synchronous-serial bit stream via the WAN port of the unit. A synchronous
connection relies on a master clock (an oscillator generated signal) to identify the
starting point of each digital bit (ons & offs or “ones” and “zeroes”) being sent. Voice
packets are spaced by time.
