Delay Characteristics — Average delay through the
Multiserver is two character times, plus the
transmission delay through the Multiserver
system. Although transmission delay is normally
very low, terminal users operating with an
echoplex system will experience this delay twice;
that is, once inbound to the computer and once
on echo outbound to the terminal. This delay is
not normally noticeable with speeds of 1200 bps
and above, but may be noticeable with speeds of
300 bps or less.
