Device Slots
The "slots" input identifies the DS0 channels—each DS0 channel is 64 kbps—that you would like to con-
nect. Each time slot in a T1 or E1 WAN port has 24 or 31 DS0 channels, respectively. When selecting the
slots you must select the same number of slots on the "A" and "B" side of the connection. The slots are selected
by entering a string that represents the slots. For a WAN port configured as a T1, the available slots are num-
bered from 1 - 24. For a WAN port configured as an E1, the available slots are 1 - 31. The following notation
should be used for entering the slots. Several examples are given below.
•
dash: (-) 1 - 4
•
comma: (,) 1,4,9
•
combo: 1 - 2, 3,6 - 7
For example, to connect a T1 Port using timeslots 1,2, 5, 6, 7, and 15, you can input any of the following
strings:
1,2, 5-7, 15
1 - 2, 5,6,7,15
1 - 2, 5 - 6, 7, 15
