Rather than using a DLCI configured for
fragmentation
on the
network side of a passthrough application, you may select a
transparent
configuration. In this case, the attached device (FRAD)
needs to be configured to a shorter segment size thus reducing voice
delays across the network A good general rule is to use one octet per
kilobit of channel speed. So for 256 Kbps channel rate, a segment size
of 256 octets is suggested. The maximum channel frame size is 2048
octets.
