5.16.3 Cross-Connect Model

The Cross-connect model allows you to access two T1/E1 links for each of four WAN cards,
for a total of eight T1/E1 links. All WAN card connections to other WAN cards are
accomplished through the cross-connect option on the System Main Screen, and must be
individually specified. User cards on systems equipped with a CPU XCON card are assigned
to WAN time slots.

5.17 Circuit Names

A cross-connect circuit in the IMACS is formed when assigning one resource to another using
one or more time timeslots. Resources are User, Server and WAN ports.
When a resource is formed when assigning a user or server port to a WAN, a circuit is formed
and given a name according to the type of circuit and type of resources assigned Table 5-8 lists
the default circuit name assignments.
