Specify channel hunting
The hunting mode defines how the available
time slots are filled. The cyclic modes use a
’round-robin’ implementation. The ’up’ and
’down’ modes define whether the time slots are
filled at the lowest or highest available slot, i.e.
’up’ means that always the lowest available slot
is used, ‘down’ uses always the highest
available slot.
Step 5 node (prt-isdn)[ slot/port ]#channel-
numbering etsi
or
node (prt-isdn)[ slot/port ]#channel-
numbering pss1-old
Specify channel numbering
Some older Q-SIG variants make use of a
channel numbering scheme that differs from the
standard ETSI method. In most cases the ETSI
numbering applies. Unless the connected ISDN
devices and configured protocols require a
different scheme, make sure the numbering is
set to ETSI.
Example
Configure PRI port 1/0 as clock master. From the Local Exchange timeslots 1 through 20 are
available and the total number of concurrent calls shall be limited to 10. Use down-cyclic channel
hunting.
172.16.40.71(cfg)# port isdn 1 0
172.16.40.71(prt-isdn)[1/0]# clock-mode master
172.16.40.71(prt-isdn)[1/0]# channel-range 1 20
172.16.40.71(prt-isdn)[1/0]# max-channels 10
172.16.40.71(prt-isdn)[1/0]# channel-hunting down-cyclic
28.8 Example
Assume the scenario as illustrated in Figure 28-4:
Figure PBX connected to ISDN port 1/1
Configure the ISDN port 1/1 to work as a Q-SIG master port but clock-slave and allow a maximum
of eight parallel B-channel connections.
