IP Addressing
H
For a fractional T1 network when a data port is not configured (in the case of
voice only), a single DDL can be used to connect to a remote site.
NOTE:
When dealing with IP addressing, your Information Systems (IS) department
needs to be involved since they typically dictate the IP addressing scheme
used in an organization.
