3.11.2 Cross-Connect Model

The Cross-connect model allows you to access one T1 links for each of two WAN ports, for a total of four T1 links. All WAN port connections to other WAN ports are accomplished through the cross-connect option on the System Main Screen, and must be individually specified.

3.12 Circuit Names

A cross-connect circuit in the IMACS-200 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 3-3lists the default circuit name assignments.

	Table 3-3. Circuit Names
user_circuit	user port (FXS, to WAN)
net_circuit	WAN port to WAN port
usr_circuit	DS0 port to WAN port

Note: Not all circuits formed in the IMACS-200 system have a direct relationship with a slot and unit. These types of circuits are not maintained by the CNA. Circuits made manually from the Cross Connect screen are not be affected by other resources. Examples of this type of circuit are WAN-to-WAN and user circuits.

3.12.1 Display and Change Circuit Names

Circuits can be displayed on the Cross Connect screen by pressing the "x" key from the main screen as shown below.
