Configuring Support for PBX Signalling Protocols
Configuring Q.SIG PRI Signalling Support
MC-423
Cisco IOS Multiservice Applications Configuration Guide
Step 3
Router(config-if)# isdn switch-type
[primary-qsig-slave | primary-qsig-master]
If you did not configure the global ISDN switch type
for Q.SIG support in Step 1, configures the interface
ISDN switch type to serve either as the primary
Q.SIG slave or the primary Q.SIG master.
The same conditions that apply to this command in
global configuration mode also apply to this
command in interface configuration mode.
Note This interface command overrides the global
isdn switch-type command setting for this
interface.
Step 4
Router(config-if)# isdn overlap-receiving value
Activates overlap signalling to send to the destination
PBX.
Step 5
Router(config-if)# isdn network-failure-cause
[1-127]
Specifies the cause code to pass to the PBX when a
call cannot be placed or completed because of
internal network failures.
Step 6
Router(config-if)# isdn bchan-number-order
{ascending | descending}
(Optional) Configures the ISDN PRI interface to
make the outgoing call selection in ascending or
descending order.
The default is descending order, in which the first call
from the Cisco MC3810 uses channel 23 (T1) or
channel 31 (E1). The second call then uses channel 22
(T1) or channel 30 (E1), and so on in descending
order.
If you select ascending order and the PRI group starts
with 1, the first call uses channel 1, the second call
uses channel 2, and so on in ascending order. If the
PRI group starts with a different time slot, the
ascending order starts with the lowest time slot.
Step 7
Router(config)# controller {T1 | E1} 1
Enters controller configuration mode. Q.SIG is only
supported on controller 1.
