LEDs
Virtual D-Chels
ATM-TRK (Circuit Emulation Service Circuit Pack)
Non-facility associated signaling is not supported under ATM-CES, so you must reserve one
port in each signaling group for use as a D chel. Use chel 24 when emulating a T-1 ISDN facility,
anD-Chel 16 when emulating an E-1 facility. The D-Chel can be any physical port from 9 to 32.
Virtual circuits
The TN230x can support a varied number of virtual circuits, depending on the switch and the
administration of the circuit pack.
Virtual trunk groups
You cot bundle physical DS1 ISDN-PRI circuits and virtual ATM-CES circuits into the same
trunk groups. Virtual circuits can only be assigned to all-virtual, all-ATM trunk groups.
The ATM circuit pack LEDs give you a visual indication of the condition of the TN230x circuit
pack (Table 52: ATM-TRK LED interpretation).
