Virtual trunk groups. You cannot bundle physical DS1 ISDN-PRI circuits and
virtual ATM-CES circuits into the same trunk groups. Virtual circuits c an only be
assigned to all-virtual, all-ATM trunk groups. Table 9-113 lists the possible
trunk-group capac ities.
Table 9-114 shows the ATM CES capacities for b oth T1 and E1 circuits.
LEDs
The ATM circuit pack LEDs give you a visual indic ation of the condition of the
TN230x circuit pack (Table 9-115).
