IPORTN - Port configuration buffer (zpconf_type)

This array contains the configuration bytes for each port on the Mux card. The Port statements in the Port-Definitionsection of the TTGEN configuration file are used to define the initial values of this array. Each element of the array is associated with a single port on the Mux card. Each element can be dynamically configured by calling the zport routine. The layout is similar to the data portion of the $PORT backplane transaction command for the 2/8-channel ACC cards and is as shown in Table 3-19.

The layout for the 4-channel E1/T1 ACC card is as follows:
