Networking Features
Some networking features currently exist on more than one ISDN interface
on the Meridian 1 system. These features are listed in Table 82. The columns
list the services and the rows list the interfaces.
Networking features that do not appear in Table 82 are only supported on one
ISDN interface and are, therefore, rejected by all JTTC gateways when the
service is requested. This is the case for all MCDN features that are not
supported over the JTTC interface.
