Channel Hunting
Should be used if your PRI is limited e.g.:
• If only channels 1 through 18 are digital, and the rest are analogue. Use Low = 1, High = 18.
• If you have a PRI with only 12 channels. Set Max channel to 12.
Max Channels
Indicates the maximum number of B-channels the system is allowed to use for each of the PRI-interfaces. For E1
(ETSI/Euro ISDN), the maximum number of channels is 30. For T1 (National ISDN and AT&T Custom), the
maximum number of channels is 23.
Low Channel
Indicates the lowest numbered E1/T1 B-channel the system is allowed to use for each PRI-line when selecting
channels for outgoing calls.
High Channel
Indicates the highest numbered E1/T1 B-channel the system is allowed to use for each PRI-line when selecting
channels for outgoing calls.
Search
Specifies where the system will start searching for available B-channels for each PRI-line. If ‘Search’ is set to
‘High’, the system will start to search for available B-channels at the highest numbered B-channel. If ‘Search’ is
set to ‘Low’, the system will start searching for available B-channels at the lowest numbered B-channel.
